Wilbur ★ Posted February 12, 2020 Share #1 Posted February 12, 2020 I want to change the grind on a cutting knife to single sided bevel. Will that screw up the temper of the edge? Link to comment Share on other sites More sharing options...
donkpow Posted February 12, 2020 Share #2 Posted February 12, 2020 Generally, only if you allow heat to build or be retained in the blank. Some blanks have a core that is different than the outside of the blade. If the blade is already ground, you may be able to see if there is a core of metal that is different than the outside. 2 Link to comment Share on other sites More sharing options...

It is unlikely that blade has a core different than the outside due to the nature of the blade's construction, assuming the blade is not a 'fake' Damascus steel blade. To create that look, the blade is folded multiple times during construction. Is that your skiving knife? 2 Link to comment Share on other sites More sharing options...
donkpow Posted February 12, 2020 Share #6 Posted February 12, 2020 Get out a loupe and see if the pattern is because the blade is folded or just etched. 1 Link to comment Share on other sites More sharing options...
donkpow Posted February 12, 2020 Share #7 Posted February 12, 2020 Heat could ruin the appearance of that blade. 1 Link to comment Share on other sites More sharing options...

Actually, no, I use a Japanese skiving knife but I want to convert this to a skiving knife. Link to comment Share on other sites More sharing options...
donkpow Posted February 12, 2020 Share #9 Posted February 12, 2020 I wouldn't have trouble changing the edge, especially since it will be a working knife. If you could do it all cold that would work easily. File + stones. The folded type blade includes steel with two different carbon contents. This allows the blade to be strong and tough. Unfortunately, the high carbon steel will burn with heat applied. I say avoid power tools. The old Samurai blades are masterpieces of construction techniques and art. If you like this type of thing. 1 Link to comment Share on other sites More sharing options...
