Q: How many stones do you (Vincent) use?

A: Depends on what I’m doing to the knife and what kind of knife I’m working on. I’ll use 2-8 stones.


Q: I lost my stone fixer, what can I use in a pinch?

A: You can use another stone if the other stone is level.


Q: Budget stone fixer?

A: Our pink stone fixer.

Q: Serrated edge, how are they sharpened?

A: There are specialized tools for sharpening a serrated edge. It looks like a cylindrical file that goes through each edge.


Q: What type of honing steel is best?

A: Diamond steel for a rougher surface and to grind more of the knife’s blade. Ceramic is better for harder steels and a more delicate surface. I recommend ceramic for thinner Japan made blades.

Q: Favorite steel?

A: I like 8A steel, because the steel is easy to sharpen, making it easier to maintain.


Q: Getting rid of scratches on your knife?

A: If your knife has minor scratches, you can use a polishing compound. Deeper scratches can be polished out professionally, but the finish of the knife will be altered and the logo on knives will most likely be buffered out.
