L6 is a beautiful steel and if you have a tourch you can harden this stuff then use the same o/s torch to draw the temper down the back or the middle of a two sided blade. But L6 is a lot harder to get soft than it is to get hard and temper corectly. It will air harden to 61rc as I read ,and oil harden to around 63-65rc, read alittle about it and you'll do just fine on your own.
