Thank,s PJ and Dixie. I did NOT fully anneal them I tempered them back in my oven. I also hollow grind the handle portion of file to lighten and balance the knife.
I spend a LOT of time making the handle,s comfy, as i,ve found that i knife that doesn,t feel good in my hand doesn,t get used much.
I get most of my files from pawnshops. I need to find some new shops/source,s tho as i,ve bought out most of the one,s close to me.
