I am in the process of making a sword cane. The blade is 440C and is 24" long 1/2" wide and 1/8" thick steel. It will have both edges sharp the full length and with a deep hollow ground on both sides. I am using a 2" wheel to do the grind. I assume I need to end up with a fairly flexible blade with edge retention being not as important as it would be in a hunting knife. The secret I am thinking will be in the tempering of the blade. Can anyone give me some pointers.
Thanks

so....let me get this right...

24" long 1/2" wide and 1/8" thick steel ?

Harden at 1900F degrees and only about 15 minutes at temperature – then plate quench and cryo . Hardness out of cryo will be about 61. Temper (twice for 2 hours) at 275F for RHC60 – 325F for RHC59 – and 375F for an excellent RHC57-58.

uh, will that be a 2" diameter wheel? the blade is really only 1/2" wide? that will be some epic grinding! are you bringing it to the ckg show?
