The Whetstone 2-Sided Sharpening Stone is made from professional grade corundum and will sharpen everything from a razor blade to a cleaver and even a machete, should you happen to have a machete lying about that needs sharpening. This is the simplest type of sharpener it’s true but the company have obviously put a great deal of thought into the product.
Japanese water stones – both natural and synthetic – are known for their superior sharpening performance, not only for Japanese tools, but also on their Western equivalents. The loosely bonded abrasive grit is washed out very quickly, as it blunts during the sharpening process; this exposes new, sharp, particles that can get to work on the blade. Water stones are lubricated only with water! Never use oil!
Sharpening is really two processes: Grinding and honing. Grinding is simply the removal of metal. Honing is a precision abrasion process in which a relatively small amount of material is removed from the surface by the means of abrasive stones. Once you have the right shape, usually using a more aggressive grit, you then switch to a finer grit to hone the edge.
The Fallkniven DC3 Diamond/Ceramic Whetstone Sharpener will make a believer out of anyone willing to invest a bit of time in the process. A big advantage of this stone is that it can be taken anywhere, used anywhere, without any form of lubrication and will produce an amazing sharp edge on whatever needs sharpening. Timeless Old World tech that still dazzles.
High Grit Stones: These are also known as finishing stones with the number range going up to 8000, and give you a super refined edge.  They work great with Western knives as they cutting edge resembles a “U” as opposed to a “V”. If you are using your knife to cut meat, then you can happily stop at 4000 or 6000 grit. If you are only using it for vegetables or fruit go all the way to the 8000.
Your immediate goal is to raise a burr on the side of knife opposite to the side you are sharpening and depending on the steel, the grit of stone and how you are doing, it will be either a very quick process or it will seem like it takes an eternity. Patience here will reward you, believe me. The sharpening process is incomplete with no burr creation on your first stone. (Yes, it is possible to stop at that magic moment without the burr forming but we are not there yet, we don’t even need to go there, ever, I am just mentioning it so those gifted sharpeners will be happy) . Think of the burr as the debris that is making the knife dull being forced down the blade towards the edge and over to the other side of the by your sharpening prowess. You form the burr, that knife will get sharp, no burr, you just need to look at your work. A Loupe is handy here, an inexpensive magnifying device with a light that allows you to see the edge very well, if you are not forming a burr, you are not reaching the edge. (Having a loupe also makes you look cool and scientific, like a Sharpologist).
For this type of hand held manual sharpener the 463 does an extraordinary job thanks mostly to the diamond abrasive wheels. You get an edge that’s both razor sharp and burr-free, as if you spent an hour working the edge on an oil stone. If people make a mistake with the 463 it’s that they assume more pressure is needed than actually is. Keep in mind though that it really shines on serrated and straight edged, double bevel Asian-style knives.
Push the point you want to sharpen with your fingers. While keeping the angle and pushing the point with your fingers, stroke the blade until it reaches the other edge of the whetstone, then pull the blade back until it reaches the edge of the whetstone. This back and forth is counted as one stroke. Repeat it for about five strokes until you can see or feel some small burrs (edge curvatures) Then move the position of your fingers to where you have not sharpened yet, and repeat this five strokes of sharpening processed from the tip to the base of the blade.
The smaller the angle between the blade and stone, the sharper the knife will be, but the less side force is needed to bend the edge over or chip it off. The angle between the blade and the stone is the edge angle – the angle from the vertical to one of the knife edges, and equals the angle at which the blade is held. The total angle from one side to the other is called the included angle – on a symmetric double-ground edge (a wedge shape), the angle from one edge to the other is thus twice the edge angle. Typical edge angles are about 20° (making the included angle 40° on a double-ground edge).[1] The edge angle for very sharp knives can be as little as 10 degrees (for a 20° included angle). Knives that require a tough edge (such as those that chop) may sharpen at 25° or more.
It is sometimes too confusing on understanding the right sharpener that right to our tools. Then using the chart above you can consider on what is the right stone. Green, red, yellow and blue line they consist of the most familiar and affordable models of sharpening stone to purchase. You can see the performance of each stone in the chart. Silicon Carbide, Aluminum Oxide, and Arkansas they are typically used with the oil (Oil Stones). Waterstones (Synthetic Waterstones) are generally made of Aluminum Oxide too, then people also use oil in place of water with their Waterstone or use water on their Silicon Carbide sharpening stone in place of oil. In this group, Waterstones is the most preferred because of its easy for sharpening edges in shorter time.
I enjoy these stones so much that the feedback is not a deterrent at all for me, I don’t even think about it. The results are always nothing but top notch, they deliver exactly what I want, some of the sharpest knives I have ever produced were sharpened on Shapton Glass stones. They may be thinner but they last a very long time, they are easy to maintain as well,
Sharpening stones have been around since the dawn of civilization for a very good reason: they work. Yes, they’re more labor intensive than most electric sharpeners but they also allow you an unprecedented level of control. Once you get used to something like the Fallkniven DC3 Diamond/Ceramic Whetstone Sharpener you may never take out your electric sharpener again.
The stones from Shapton are probably the hardest of all Japanese sharpening stones. They will remain flat for a long time. They are therefore the best choice if you are looking for a relatively coarse stone that cuts quickly without having to be dressed repeatedly. The finer-grained stones also work very well. But Shapton stones do not provide the mirror finish you can achieve with softer stones.
The DuoSharp Plus stones are nicely sized at 8” long by 2 5/8” wide and have two grits on each stone to maximize value. The Plus in the name refers to an area of continuous grit in the otherwise interrupted grit surface of the stone. This area is for sharpening edges with fine points that might be difficult on the interrupted surface. A coarse/fine DuoSharp Plus stone is a good single stone to start a sharpening toolkit.
Whichever method you choose, be it a waterstone (also known as a whetstone), or a pull-through (either V-shaped or ceramic wheels) it's important to regularly hone your knife with a honing steel, which we'll also cover below. You'll be pleased to hear that you won't have to reach for the stones too regularly – once every two or three months should suffice. 
Beginning on the right side of the knife, move from tip to heel and heel to tip, then flip the knife and repeat. For the left side, it’s opposite—start at the top of the stone to reach the heel area completely. So, you will move from heel to tip and then tip to heel. Remember to apply and release pressure as you did earlier, exactly the same as in Step 2, but with light, refining pressure.
Next we sharpen the opposite side of the blade. Just as you did before, sharpen the knife keeping an angle of 10' to 15'. Push the point you want to sharpen with your first, second and third fingers. While keeping the angle and pushing the point with your fingers, stroke the blade until it reaches the other edge of the whetstone. Then pull the blade back until it reaches the edge of the whetstone. This back and forth is counted as one stroke. Repeat it for about five strokes until you can see or feel some small burrs (edge curvatures).. Then move the position of your fingers to where you have not sharpened yet, and repeat this five strokes of sharpening processed from the tip to the base of the blade. When your whetstone becomes dry, occational watering during  sharpening process will also help and improve smooth sharpening.

The stick – With a stick sharpener hold the sharpener in front of you (facing away from you) with one hand and the handle in the other hand. Hold the base of the knife against the base of the tip at a slight angle and then push the blade along the stick pulling it across the stick at the same time. The tip of the blade should cross the end of the stick. To sharpen the other side of the blade place it under the stick and repeat the process making sure to reverse the angle at which you are holding the knife against the stick.

This is a good size stone and has the two different grits needed for knife sharpening. No instructions were included, but there are many websites with written and video instructions, so this is not an issue for most people. A fair amount of dust is generated during the sharpening process, so protect the work surface and wash the knife after sharpening is completed.
Now move the blade – with a little pressure – in regular movements up and down along the sharpening stone. Always maintain the angle between the blade and stone. You will notice a burr become visible after five or so movements. Mentally divide the blade into three sections if the knife has a large blade. Always start with the tip and work back towards the bolster.

I've only used it to touch up the edge on an ESEE RB3 and a pocket folder so far, but it has done very nicely for those tasks. I found that using the rounded edge works best for me in order to be able to run the length of the blade without hitting the leather lanyard. I'll hopefully try it out soon on fish hooks, too. A worthy and handy accessory, and cool looking necklace, to boot!

Ease of use – Most people in search of a mechanical sharpener want one because they don’t want to be bothered with trying to achieve a perfect edge themselves using a stick or sharpening stone. They want predictable, first class results every time. In that case it’s important that the electric powered device is easy to use, achieves results quickly and with little effort and is designed with user safety in mind. Keep in mind too that it’s easy to apply too much pressure when using a mechanical sharpener and when that happens you’re likely to see unsatisfactory results. In addition there are subtle differences between mechanical devices designed for Asian-style knives and those designed for Western-style knives. This has to do with the sharpening angle discussed above. Don’t get an Asian sharpener if you don’t need precise control over your cuts.

This is great combination but you don’t need them all to get started. As your budget allows, start with one stone and although I like to start with a coarse stone, the 400 Chosera is a little coarse to start the learning process with and you would need another stone in a higher grit to finish. So if you want to start with one water stone, and that is perfectly okay, select the 1,000 grit stone, it will deliver an edge that will startle you, with practice of course. Also, just having a water stone in your possession is going to motivate you, trust me.

While it may still feel like there is a lot to choose from, you don’t need a lot of of stones, you just a several good varieties to choose from. To summarize I will indicate below what my favourite stones are in each grit. Yes you can mix up the brands when sharpening but my recommendation is to buy a combination of 2-3 stones of the same brand and go from there.
It will be tempting to raise the angle here to get to the edge quickly, that is not the way to go. Re-paint the edge/bevel if necessary and try again. You can flip the knife prior to burr formation and work on the opposite side. Repeatedly feel for the burr with your thumb by running it very gently down the blade and over the edge, if the burr is there it will be very obvious, you need to create the burr along the entire length of the blade. Once you have done that, (you have accomplished what most people will never try) but besides that, you have to do the same to the other side of the blade.

After you have completed a few passes over the stone on both sides, you can move to the final stage. This time it is P1 pressure, just enough pressure for you to control the knife. Ensure your stone is wet and now repeat the motions but with very very light pressure. You really need to focus here and ensure you are reaching the edge of the edge and again, just a few sweeps on both sides of the knife.
Just to prove that we're not merely sharpening geeks, here's an interesting side note. The word whet pops up in some unexpected places. A small species of owl is called the saw-whet owl because the sound it makes reminded people of the sound made when sharpening a saw with a file. And the phrase "to whet your appetite" comes from the idea of your hunger growing sharper at the thought of food.
When you apply a sharp knife to the surface of a tomato, cucumber, carrot or other food item it should - if you are holding it firmly and applying minimal pressure - sink into the particular item without effort. As such all you really need to work on is your technique and making sure you keep your fingers out of the way. With a dull knife however things aren’t quite so simple. When you apply a dull blade to, say, a tomato it’s not going to slice into the skin. Instead the skin will be able to push back meaning you’ll need to apply ever more pressure to get the knife to penetrate. Increasing the pressure on the knife increases the likelihood of the knife slipping off the offending food item to one side or another. And if it slips to the side where your hand is attempting to hold the vegetable steady you could be in store for a very nasty cut. Because even a dull knife will cause injury if there’s enough force behind it.
A: People often make the mistake of assuming that just because a mechanical knife sharpener will sharpen the edge of a knife that means it will sharpen any type of cutting edge, including scissors. This is a mistake and can wind up being a costly mistake when you have to replace both your scissors and the knife sharpener. There are sharpening devices specifically designed to handle scissors. Or you can bring your scissors to a sharpening pro who will usually have the right equipment on hand to also sharpen scissors. Another thing to keep in mind about trying to use a sharpener to sharpen scissors is that by using the device in this fashion you are likely voiding the warranty. As such if you damage the device trying to sharpen scissors you’ll need to pay to have it repaired or replaced as the warranty won’t cover it. Also, certain types of high end scissors also come with a warranty. And, just as with the sharpener itself, if you try to sharpen them using a mechanical sharpener you can say goodbye to the warranty protection. The bottom line is to always use the appropriate tool for the job at hand. That way you’re assured of the best possible result and any warranty remains in effect.
if you have regular kitchen knives it will not work- first its to deep and the blade does not stick out, not dinner knives but cooking knives. of all the knives i put in it only 1 was wide enough to stick out. the device does not hold the blades. all the blades tested fell out of it, even a hunting knife, maybe its for 1 type of knife and they are selling it as the must have tool for all.. that said sell something useless for a few bucks that most cant use, they got a few bucks that most will blow off and not worry about a refund.. DONT WASTE YOUR MONEY.

Ceramic sharpening stones were the early replacement for natural stones. Unfortunately there are huge differences in the quality of ceramic stones so be wary. Some are extremely soft and dish out very quickly and at the other end of the spectrum some are so hard they tend to glaze over in a hurry. Ceramic stones need a good soaking for about 10 or more minutes to saturate the pores of the stone prior to use. As all knife steels are different we tend to find that ceramic stones tend to work better with some knives over others. There are no hard and fast rules but we like ceramic for Ao-ko and single edged knives. The Kaiden Ceramic stones are the fastest cutting Japanese stones in Australia and are recommended for advanced users.

The angle on a Buck Knife is set based upon how we feel the knife will be used. Heavy use needs a strong and blunt "V" while skinning or filleting would need a deeper but more vulnerable "V". We tend to grind to 13-16 degrees per side (see illustrations). If you match the existing edge angle and hold the knife against the stone to cut evenly across the edge grind, you will produce an edge with a similar angle.
Manufacturer contacted and sent a new one for replacement. Great customer service but replacement item was nicked on the corner. It was still usable so i didn't bother to ask for another replacement. I would recommend item to be shipped in another box instead of an over-sized yellow envelop which is not adequate protection. Item sharpen my knife pretty good though..
Now that you're holding the handle and the blade is in position, gently apply some pressure to the belly of the blade with your left hand fingers – "roughly the amount of pressure to semi depress a sponge," says Warner. Starting at the tip, glide the blade up and down the stone – around five strokes up and down is a good number. Then move to the middle – five more strokes. Finally five strokes up and down on the heel.
