Help Please! I am making a bowie (1/8" thick sawblade steel) with an upswept flat grind blade and it has a pretty dramatic point. I have made a couple of test blades and feel that the HT and temper are about right (only a slight wave when cutting a nail in half and breaks at about 45 degrees). I can heat treat and temper it with no problems, but it is still too brittle and breaks easily. How can I anneal this area without ruining the HT and temper?
