It takes time to sharpen a knife correctly. I spent about 30 minutes on an already fairly sharp knife. I then spent two more sessions of about 10 to 15 minutes each. I took it a bit further with a 6000 grit stone and this puts a nice polish on it. Instead of cutting through an onion, it glides or slips through it. It was truly shocking to me to use a really sharp knife. It may take a bit of time to get it right the first time, since this was my first time with a water stone, but it was well worth the effort. I have been trying to figure out the best way to get a really sharp knife.
The more you use the sharpening stone; the edges of each particle within the stone tend to become slightly rounded over time. When you notice that it is taking much longer to hone blades and edges, it means you need to replace the stone with a new one. Sharpening stones come with decks that make it convenient to keep the tool in balance on the stone.
Let's begin by sharpening the knife from the front side. Western knives are not evenly double-beveled. The ratio for sharpening them is 80% on the front side and 20% on the back side of the blade. (The angle of the blade to the sharpening stone surface is about 10 degrees.) All knives are sharpened from the cutting edge to the spine of the blade. You hold the handle with your right hand, push down on the side of the blade with the fingers of your left hand, and sharpen by moving the blade toward the center of the stone.
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.
It's okay, but wish I purchased a different stone. The stone is too soft, therefore knife slowly cuts away the stone causing it to be unlevel. I am completely unable to keep it level, thus for me the stone became worthless. Feel the stone is cheaply made; I'd suggest buying a slightly more expensive whetstone. At end I had to trashed this stone and buy a new stone.
I would say they are worth the money. Go for it. I took a blunted Pampered Chef kitchen knife from completely dull to razor sharp in about an hour (of bumbling and repairing mistakes LOL) heavy grinding. If you have a severely damaged blade, grab one of those cheesey two sided stones from Harbor Freight to do your heavy grinding. From there these stones will work very well.
A single stone of 120 grit and a combination stone of 1000 and 3000 grits come along with a stone holder all for a price of less than many other individual stones. The stones are 6 7/8" long and 2 1/8" wide. A flattening stone of some kind would be needed, but with economical options available in those, the overall price of this kit would still be low. This entry level set is a good budget minded option.
This knife sharpener features precision-ground tungsten-carbide sharpener on bars which can automatically adjust to provide different blade angles. And just by changing hand positions, you can easily fine-sharp or hone the knife as often as you like. With regular honing, you will maintain a sharp edge without removing metal and extending the lifetime of the blade.
This set of two Norton combination waterstones provides four grits and also includes a flattening stone as an added value. The 220, 1000, 4000 and 8000 grit sides will handle everything from aggressive shaping to final polishing. They are 8" long by 3" wide, big enough to handle most knives and tools easily. Our most popular waterstone kit, this has everything you need to both sharpen with waterstones and maintain the stones themselves. A great starter set.
