I had a friend come by today and asked me to put a new handle on his knife its a cheap old old fillet knife. After i heated the handle and chisled it off the brand G 96 APPEARED.On the blade it says Flex fillet 2020 . What type of steel is this maybee ats34 .????????? i am having a hell of a time to try and drill pin holes as there were none from before for pin stock. ANy suggestions are appreciated. Ive drilled hardened steel but knothing like this I cant hardly put a mark on it and resharpend a centre punch after one hit . It took the tip clean off my centre punch wow. I would guess RC of in the 60 s plus. The blade flex s unbelievable.My friend says it hold s a edge like no other knife he has had. please help me to figure out how to drill these holes. I dont want to take the temper out and i did try some mild heat. kellyw
