But how do you know you start with a straight blade? And you do not inadvertently “straighten” a curve or warp with the shims? Not sure that it matters because the only thing you need is it to be anally retentative eyeball straight and you seem to have that in place already
Depending on how thick the linerlock is i would temper to 400f so that it fails plastically not brittle, but i think more important would be to use the lower austenitization temps and make stress risers very very gradual... but this is purely from a theoretical point of view and not an...
Tip from the useless grinder who loves fine tips... leave a 1/4” wide tip at the tip, above the spine and a teeny bit longer finishthe bevels then shape the tip... very slowly and cool grinding
Matherton forge is my go too place for any carbon toolsteel i use... hypefreeblades too, is a bit quiet now and i still struggle to make the theory into practice or interpret results i will be sure to post my questions here... there be lots...
I recently read Verhoeven’s pdf and he reported on a method of grange of normalizing at 900 degc or 1650f for 15minand quench and then three cycles of 790 degc for 4min and quench in oil... then take to austenitizing temp 830 degc and quench... it gave me decent grain i think and hardness...
i cut with it, i sharpen to a ridiculously low edge angle 7-10dps and then do kitchen work or whatever with a test knife, then I see how it degrades... for everyday / outdoors knives i take a heat treat sample grind it and put a very fine edge and whittle / cut hardwoods and see how the edge...
Any steel will do for a flexi like this, use something that comes in sheets not rollsand is about 0.1” or less... a good heat treat on any steel will be good...
I prefer elmax above Rc61 for all purposes... Rc 62+ feels subjectively better to me for the kitchen but if you overdo it then the damage is more... which is normal... the huge big BUT is that the wear resistance at 61+ is so high it is quite a bear to grind cold enough and thin enough for...
Hi i found this forum recently and looking for good solid heat treat info... trying to areange everything i read into a manageble order in my head, it has been a process...
