Just finished up what I would call a hunting/camping knife so I started to temper it but realized it had a small warp on just the edge, and if I grind it out I’ll lose at least a few millimeters off the edge, which is already lower than I want it to be...is there any risk or permanent effects of heat treating twice, even after a first temper? So far I heat treated and tempered it but now it kind of has to be hammered straight again
