The kind of tech we love: compact, reliable, durable, attractive and cheap. Purists may feel that other sharpeners will produce a more perfect result but for 99% of the human race this sharpener will be everything the doctor ordered. Your blades stay sharp for a good long time thanks to the 2-stage sharpening process and if you’re a left handed chef you’ll love the fact that it works just as effectively for you as for anyone else.
Therefore, the first step to choosing a whetstone is to determine your intended purpose and then choose your whetstone accordingly. For instance, when sharpening tools that do not require a fine edge, you should choose a relatively soft, coarse, stone such as a Norton Crystolon water stone. However, for sharpening tools that do require a fine edge, a somewhat harder Norton India oil stone would be a good choice. But, for sharpening hunting knives where an exceptionally fine edge is required, a Novaculite or Coticule oil stone would be the best but, most expensive, choice. So, the process of choosing the correct whetstone for any given purpose is to first determine how fast you would like for the stone to cut and how fine an edge you need, and then choose either a soft, coarse, stone or, a hard, fine, stone of the appropriate type and grit.
Knife sharpeners work by stripping away metal to form new bevels, ideally at an angle that closely matches the original. But you don’t need to obsess over getting the angle exactly right. For most kitchen knives, consistency trumps precision, says David Marks, a professional knife sharpener and owner of Stoddard’s, a Boston cutlery store and sharpening service: “As long as you keep the same angle throughout the process, it doesn’t matter if you’re off by a couple of degrees from the original angle.” Since consistency is key, many knife sharpeners incorporate some means of setting the angle for you.
I recently placed my first order after finding you on the web while looking for grinding wheels. I am a customer for life. Here's why. My first order was a simple white grinding wheel for a "normal joe's shop". When I received the wrong wheel (150 grit instead of the ordered 100 grit) I called and without hesitation or the 3rd degree another wheel was sent off. No questioning of my integrity, intelligence or honor. Simply "I am sorry, we'll send the correct wheel off immediately..." The right thing was done by a neat guy. I was treated like an adult. Unbelievable in this day and age...proper...and priceless. Price, performance, responsiveness and customer service par excel-lance. 6-Stars! All my sharpening orders, albeit small shop orders, will now be with you. Promote you I will.
Although this is somewhat counterintuitive, soft, heavy steel is often more resilient to nicks and dulling than harder steel. Carbon steel, known for the high level of attention and care it demands, actually holds a better edge and is more easily sharpened than its stainless counterpart. On the other hand, while harder alloys require less daily honing, some high-hardness steel can become brittle and prone to chipping. For example, it's important to use only smooth honing rods on harder Japanese-style knives to prevent micro-serrations that diminish the edge and lifespan of the blade.
The Work Sharp WSKTS-KO Knife and Tool Sharpener is a handheld device, which is optimized to handle various sharpening jobs. It comes with a belt sander, which spins around following a triangular configuration. It has a set of angles on either side, which can be adjusted from 15 to 30 degrees, depending on your sharpening needs. Unlike other electric knife sharpeners, which tend to overheat during high speeds, the speed of this one is adjustable.

This is a good quality stone for a beginner looking to learn about hand sharpening knives and blades. It holds up well, especially for the price point. New sharpeners are prone to gouging and scratching stones, pushing too hard, etc, and this stone handles the abuse nicely. The no slip base is very effective at cementing the stone in place, which is a critical safety feature.

We bought this for our parents as a little random gift to have at their home. I suggest using it for your cheaper everyday knives. It sharpens really well! The only drawback is that my husband noticed that eventually it bent some a few of the cheapo knives. The knives were cheap, but this sharpener ended up damaging them (but still got them to be sharper). If you don't really care for the little dings and changes to a small portion of your knife, as we don't with our cheap ones, it's still worth using! I suggest to only use them on your more inexpensive knives because I'm not sure how I'd feel using them on more expensive knives, because you really don't want to damage those in case it does the same thing to them!
The 8,000 grit Kitayama is definitely a popular 8K stone, it is my favourite, and the feedback has much to do with that. It is silky smooth and feels creamy when you use it. When reaching refinement levels of 6k and above, polished bevels/edge are inevitable, and often sought after. The level of polish from this particular stone is very beautiful, assuming that you have done some refinement prior to this but it is a wonderful 8,000 grit stone.
Actually, the company contacted me to make sure I received the stones and that I was happy with them. Excellent service. The stones are great! I'm pretty much a novice so the clear instructions that came with the stones and the eBook instructions were wonderful. The eBook had quality pictures demonstrating the use of the stones and the written instructions were clear and to the point. Within minutes of opening the box I had the stones figured out and sharpening my AF survival knife, my pocket knife and a couple of my wife's kitchen knives...which included a very expensive chef's knife. Very satisfied with this product and highly recommend it.
Finally a sharpener that gets my kitchen blade REALLY sharp. I've bought countless blade sharpeners and this is by far the absolute best I've ever used.(and NO I am NOT paid by the company, just an amateur chef who loves a really sharp knife) This little beast is small for easy storage and the suction cup {so far} really grips any clean flat surface and doesn't slip at all once the lever has been pulled down. It only took me 3 slow pulls to get a deadly thin edge. I have already used it to cut potatoes, onions, and my personal favorite, tomatoes and each time it was like cutting through warm butter...love...love...LOVE this product and will definitely be buying more....just hope they don't screw it up and change things like most companies end up doing?!?! Hahaha
Now it's time to polish. This is when you'll swap over from the coarse grit to the finer grit (make sure this side is wet, too). I found the knife still had a bit of grime on it, so I gave it a wipe clean beforehand. The motion is exactly the same as with sharpening, but you can apply slightly less pressure, and limit to roughly 30 strokes on each side. 
It is believed that Vikings suspended these knife sharpening tools from their belt. However, it is not exactly clear, even to scholars, how the Vikings wore these pendants. We laced ours with a versatile, adjustable high-quality leather cord and packed it in a USA-made muslin pouch so you get to choose how to wear it or carry it. Wear it around the neck for the most Ragnariest looking necklace you’ve ever seen, cinch it all the way down so that it can be hitched to your belt or clipped onto your pack, or simply pocket it while still contained in the hand-stamped muslin pouch.

For absolute dull knives, the first stage has to be through the coarse slot that works on a diamond wheel system. Diamond is one of the hardest substances on the face of the earth and ideal for sharpening. By pulling even the dullest of knives through this slot, the diamond wheel sees to it that an angle is formed on both sides a knife’s bevel edge.


These are unquestionably great starter stones. After all the sharpening done over the course of a couple days, they're still perfectly flat, showing little to no signs of wearing down. Mind you I did watch tons of how-to videos online before undergoing the endeavor, so I knew how to try to make the stone wear evenly. But, my 15 year old nephew who was working on the Ontario, as I told him he could have it, if he wanted to fix it up, didn't watch all those videos and I didn't see any uneven wear on his stone after working it about a half hour either.
