Double-Sided Diamond Bench Stone (Medium/Fine) Key Features: - Medium Grit (280) Green Side - Fine Grit (600) Blue Side - Non-slip Base - 100% Uninterrupted Diamond Coating - Screw Holes in base for bench mounting The full edge-to-edge uninterrupted diamond surfaces on the benchstones make for quicker, more efficient sharpening, at a high value. The green, Medium side (280 grit) will quickly recondition your blades, removing substantial amounts of material from your blade to re-define its edge. The blue Fine side (600 grit) will produce and maintain a micro-serrated working edge, polishing away the marks from lower grit stones. The 600 grit stone produces a working edge that is adequate for nearly any task, especially cardboard cutting. A perfect addition to any craftsman’s workshop, the diamond abrasives on the benchstones are excellent for repairing and maintaining a large range of tools from dull and damaged kitchen knives, to well maintained woodworking chisels. InstructionsUSING YOUR DOUBLE SIDED DIAMOND BENCHSTONE Step 1- Select the proper sided of the stone for your edge. Medium- To maintain an undamaged, dull edgeFine- To hone/polish a finished edge or for daily manitainanceStep 2- Set the Benchstone base on a stable, flat surface with the stone you have selected facing up. Note- Lubrication of any kind is not recommended while sharpening on any of the three stones. DO NOT USE HONING OIL ON THE DIAMOND STONE. Step 3- Observe the bevel angle on the blade you intend to sharpen. Then, bring the edge to the stone matching your sharpening angle to the bevel angle. Step 4- Using light pressure, push the edge of the blade across the stone in one motion, much like trying to slice a thin layer off the top of the stone. Maintaining a consistent angle is essential for the best results. Step 5- Repeat process 3-4 times on one side of the blade then switch to the other side and repeat. Step 6- Repeat this process until edge is sharp then progress to finer stones and repeat. Step 7- Clean your stones. Clean the Diamond stone with a damp rag after each use. Suggestions 1. Use a series of stones for the best results. For an undamaged edge start with the Medium Diamond Stone 2. Start with your selected stone. Use 3-4 strokes on one side of the blade. Repeat process on the other side of the blade. Repeat this whole process, switching between sides, about 3-4 times. 3. Then use only 2 strokes per side. Repeat this process 2-3 times. 4. Then 1 stroke per side. Repeat this process 1-2 times. 5. Move on to a finer stone. Be Smart, Be Safe and Stay an Edge Above the Rest! CAUTION: Knife sharpening is an inherently dangerous activity.
