Clamp-style sharpening tools use a clamp with several holes with predefined angles. The stone is mounted on a rod and is pulled through these holes, so that the angle remains consistent. Another system is the crock stick setup, where two sticks are put into a plastic or wooden base to form a V shape. When the knife is pulled up the V, the angle is held so long as the blade is held perpendicular to the base. Several cutlery manufacturers now offer electric knife sharpeners with multiple stages with at least one grinding stage. These electric sharpeners are typically used in the kitchen but have the ability to sharpen blades such as pocket or tactical knives. The main benefit of using an electric sharpener is speed with many models that can complete the sharpening process in one to two minutes. The disadvantage is that the sharpening angle is fixed so some specialized knives, like a Japanese style Santoku, may need additional attention to sharpen to the ideal angle.
If you wish, further polish or even strop the edge to the desired sharpness. This makes the edge better suited for "push cutting" (cutting directly into materials, pushing straight down without sliding the blade across the object) but generally impairs slicing ability: without the "microscopic serrations" left by grinding with a stone, the blade tends to not bite into things like tomato skins.
The humble sharpener tends to elicit more divergent opinions than just about any other type of kitchen tech. Everyone, it turns out, has their own take on which type of sharpener works best and why and most serious chefs aren’t shy about voicing their opinion. As you can imagine then there are a number of things most chefs – both professional and amateur – look for in a sharpener in order to ensure they get the one that’s right for them. These considerations include:
Finally, when you learn how to sharpen a pocket knife becomes reality, you'll ultimately see the difference in your blade. Every sportsman and kitchen guru should learn how to sharpen a pocket-knife the proper way without "nicking it" or "shaving the edges" off too much you end up with a short and stout blade. Consequently, selecting the proper pocket-knife sharpener is important so learning the in's and out's of how to sharpen a pocket-knife before and after using it is all in the practice as well as in the sharpener itself.
Chefs will do this every day, and there's no reason you shouldn't too. Before cooking, or after you've done the washing up, honing your knife will help keep it in good condition. "When you're using a honing steel, you're not actually removing any metal at all, just re-straightening that edge, to get it back in line," says Authbert. Remember that you'll still need to sharpen it every two or three months.

It will also do a bang-up job on your hunting, pocket, boning knife and more. As mentioned it does require just a bit of getting used to in order to achieve optimal results but nothing too involved. A simple, effective, no-frills sharpener.
first time buying a sharping stone. i bought this because i wanted to sharpen kitchen knives. you have to practice to get good at it, use a knife you don't care about because you might mess it up. there is some conflicting instructions online on how to use, water or no water. read as much as you can about using stones and practice, practice , practice. look up videos on youtube and internet. i had fun using it, BUY IF YOU WANT TO LEARN here is some stuff i found, they all sound like professionals http://video.about.com/culinaryarts/Sharpen-Knives-With-a-Whetston.htm?rd=1 http://culinaryarts.about.com/od/knivescutlery/ht/whetstone.htm this is a video that says don't use water http://video.about.com/culinaryarts/Sharpen-Knives-With-a-Whetston.htm?rd=1 this is a youtube video that i watched that uses water. *informative http://www.youtube.com/watch?v=KFIg9Cm-nJg
A shinkansen is a Japanese-style pull-through sharpener named after the famous bullet train. It features two sets of ceramic wheels set at the right angle for sharpening a Japanese blade, which takes out the guesswork of the waterstone. Simply hold the handle with your left hand, then saw back and forth gently through the coarser wheel to sharpen, before switching to the finer wheel to polish.
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).
Now to finish: Again with P1 pressure, trailing strokes only, this time lift the blade off the stone as you finish pushing it over the stone away from you, bring it back and repeat this 5 times, on each side. The burr should be gone and your knife will be sharp, remember, manage your expectations but if you have followed this, that knife is going to be sharper than when you started and this is just the beginning. Now you can test your knife for sharpness trying to cut some telephone book paper.
We tend to recommend natural Japanese water stones only to experienced users who are thoroughly familiar with the synthetic Japanese sharpening stones. Natural stones are not to everybody’s taste and there are inevitably many uncertainties with regard to their grit grade, which cannot be determined exactly, their hardness and their suitability for certain types of steel.
The speed and polishing ability of waterstones attract many sharpeners. Waterstones sharpen quickly and are available in fine polishing grits not found in other stone types. The ability to flatten the stones is a necessity when sharpening with waterstones, so a starting set should include a flattening stone of some kind. Our article, How to Flatten a Waterstone, has more information about keeping waterstones flat.
I can personally verify that this will get your knives very sharp. I will spare you all the gory details, but the picture is of the instructions the ER sent me home with after stopping the bleeding and patching me up. I have to say, that’s not what I had in mind regarding “Thanksgiving tips”. So: not only will knives slide easily through spinach, but they will go through finger and fingernail like a hot knife through butter after being sharpened by this whetstone. Very clean, straight cut. Impressive, really. Just take it slow and don’t be a moron like me.
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). 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.
Put the pointed, narrow end of the sharpener up against the open end of the gut hook. The narrow, pointed end of the sharpener should face in toward the thickness of the blade, away from the edge of the gut hook. Match the angle of the sharpener to the original edge angle. This will maintain the correct sharpening angle and prevent you from getting cut by the blade tip. Hold the same angle when sharpening each side of the gut hook.
As you see in the pictures, it is always very important to keep same angle of about 10' to 15', which is about two coins height between the blade and the whetstone. Gently 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.
