Our take on the Double-Sided White Corundum Sharpening Stone

This is a two-grit water stone: a coarse side for dull or damaged edges and a fine side for finishing and removing burrs. It sits in a thin, flexible non-slip base that keeps it steady on a counter. It suits home cooks and DIY users who want one stone for kitchen knives, scissors and hand tools. Against diamond plates it wears faster and needs soaking, but it is simpler and more forgiving for beginners.

About the Double-Sided White Corundum Sharpening Stone

This is a double-sided sharpening stone made of white corundum. One side is coarse and the other is fine. It sits in a non-slip silicone base that keeps it in place while you sharpen.

Use the coarse side first to repair badly dulled edges. Then use the fine side with lighter pressure to remove burrs and smooth the edge. The fine surface helps avoid damaging the cutting edge. It works on kitchen knives, household knives, sports knives, pocket knives, scissors, hand tools, woodworking tools and carving tools.

Soak the stone in water for 5 to 15 minutes and place it on a stable surface. Hold the knife at an angle of 10 to 30 degrees and use light pressure, moving the edge across the stone from front to back. After use, wipe the tool with a damp cloth, rinse the stone with water and dry it. A soft brush can clean the stone's surface.

Questions and answers

What grit are the two sides?
The stone is labeled only as coarse and fine, with grit numbers printed on the side. The coarse side handles dull or damaged edges; the fine side finishes and deburrs.
Do I need to soak it before sharpening?
Yes. Soak it in water for 5 to 15 minutes, then set it on a stable surface. Keep it wet while you work.
What angle should I hold the knife at?
Hold the blade at roughly 10 to 30 degrees to the stone and use light pressure, edge trailing from front to back. Use the coarse side first on dull knives, then the fine side.
Will it sharpen scissors and tools, not just knives?
Yes. It is meant for kitchen and pocket knives, scissors, hand tools, woodworking tools and carving tools.
Does it stay put while sharpening?
The flexible non-slip base is there to keep the stone in place on a stable platform during use.
How often should I use the coarse side?
Use coarse grinding mainly for badly dulled edges. The instructions suggest re-sharpening with the coarse side about every six months, depending on use.
