    Smith's 4" Diamond Combination Bench Stone features coarse and fine grit sharpening surfaces. These surfaces contain multiple layers of micron-sized monocrystalline diamonds and a unique sharpening surface with an overlapping oval hole design. This innovation speeds sharpening by collecting and holding the metal filings which ordinarily build up during the sharpening process. Each stone has a "micro-tool sharpening pad" and a sharpening groove for fish hooks or pointed tools. The soft grip rubber handle is designed to make sharpening safe and easy, and when you are finished sharpening, you can store your stones in the handle for safekeeping.

    1. Use water or Smith's non-petroleum based honing oil as your sharpening lubricant, but stone can be used dry. DO NOT use petroleum based oil on your stone as a sharpening lubricant.
    2. Place your blade on the end of the stone at the desired sharpening angle.
    3. Push the blade away from you just like you are trying to carve a thin slice off the top of the stone. Use moderate pressure; let the diamond do the work. Repeat this pushing stroke 3 or 4 times. Try to maintain the same sharpening angle with each stroke. This is the key to obtaining the sharpest cutting edge.
    4. Now sharpen the other side of the blade. Place your blade on the opposite end of your Smith's stone and repeat steps 1 and 2 this time pulling the blade toward you.


    Always dry your diamond stone surface after each use and before storing.

    Occasionally clean your stone with soapy water and a mild brush.

    The best sharpener I've used.

    • Produces High Quality Edges
    • Inexpensive
    • High Longevity
    • Nickel plating can knick with time.
    If you even halfway know how to use a sharpener, this tool makes it easy to produce razor sharp edges, even on the most stubborn to sharpen high-carbon steel. As soon as I buy a knife (I go through them quickly) I immediately do the paper sharpness test out of the box, and if it passes(which it better if I'm buying it), I'll do a quick run through on the knife with the fine side of this. Match the angle the factory gave the edge as you sharpen and your knife will be near scalpel sharp. My everyday carry knife is 13" infantry style Bowie knife with a 7" blade. The factory edge passed the paper test and was "sharp". But 15 minutes with the stone and the blade was on a different level of sharpness, one that I can physically feel in the edge itself with my fingertips from the blade's tip down. Now that's an edge I can carry on my hip with confidence! The blade will easily gut and halve smaller game with a single stroke. Large animals such as feral boars can be quartered and decapitated for trophying purposes as easily as if they were made of butter. My only critique (as others have pointed out) is that eventually the plating (nickel I believe) will likely knick as you use it because it is softer than the knife's steel. Over the years this has happened to mine, but I've personally had no issues with it affecting the edges of my blades like others have reported. For me, it has been a purely cosmetic defect. As long as the stone continues to produces edges that make flesh and bone feel like butter and bread I'll continue to use it.

    Not happy with mine

    Atlanta, Ga
    • Convenient and easy to pack away
    • made of soft metal
    • side destroyed my ed
    Mine had a tiny indentation in the side edge of the fine side. It's gotten worse over the last 2 years. Was using it a few nights ago and my blade got caught on it, destroyed the entire edge. I'm royally pissed off

    Best In Class For The Money

    My mother got me and my father one for Christmas 4-5 years ago. Its the most successful sharpener ive owned. My last name is smith so my father has been giving them away as Christmas gifts to his brothers and family the last few years. We are proud smiths lol. I mostly use it on my daily pocket knife and I used it on all my hunting knives. being a trapper and avid hunter I use it quite often during the winter months and it has been able to bring a blade back to life every time. great job

    Best Sharpener

    This shapener will give your knife a razor sharp edge in a few minutes. I use this knife sharpener on all my knifes. I had this knife sharpener for about 2 months. And it still works well and gives you that hair shaving edge. I also love that this sharpener can also sharpen fishing hooks.

    Dull To Sharp

    I've had gone though a few sharpeners interned for pocket knives to sharpeners that come with high end kitchen knives... this sharpener will get your dull knife to a slicing though paper like a razors edge. If you have the sense and feel when a knife is being sharpened then this products is for you. (Minimal burr the better the cut). You will not regret your purchase.
