Wojtek, I've just had bad luck trying to "cut" through such plastic plus the hard high carbon steel blades are brittle and can break with lateral pressure, still have the scar
Agreed. But each cutting with a such sharp tool requires our attention. Most of incidents occur because of incorrect holding of either the cutting tool or item we try to cut. Or just because of wrong operating with a tool.
Sorry. Been doing it all from my smart phone.
OK...
