    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.

    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.

    Simple And Portable.

    I have a dual grit 6" stone that I use for everything in my house-kitchen knives, tools, and pocket knives. However, when camping it just adds too much weight to my bag and I worry about damaging it during the more rigorous trips. This 4" stone is perfect for that. It is compact, lightweight, and versatile. I use it just like my larger stone with a little bit of water. As other folks have stated it isn't ideal for larger blades but you can make it work.
