The DMT Machinist Diamond Whetstone combines both interrupted and continuous diamond abrasive surfaces into a compact portable design. The included leather case makes this stone a great gift, or a nice addition to any tool kit, kitchen drawer, or backpack. The diamond abrasive can be used without water for easy, mess free sharpening no matter where you are.
