Yea, i have built a few from old nichols files now. About 3 weeks prep time trying to get them smooth. They just wont soften up all the way. But, harden up fairly well when heat treated like 1095.This is a GREAT TUTORIAL and can be done with common tools!
I love 01, it will save a lot of time too as it is precision ground and annealed. This will help as you won't have to do a lot of preliminary prep work with the blanks. And its pretty tuff stuff that makes a nice knife!!
