Blades for my Jointer/Planer/etc?
The steels we use won’t stand the heat generated by power tools. This includes lathe tools (which really are power tools – think about it.) Hardness retention while at high temperature is why there are high-speed steels but we don’t need that quality in hand tools so why pay more for what we don’t need? There are plenty of high quality planer and jointer knives and turning tools out there. Use the force.
