File Knife Tempering - An unlabeled file might be around 62 Rc or so and therefore if the knife is higher than 62 Rc (which most low alloy high carbon steels should be For this I will be using the "Gough Jig". It's nearly identical to the one in the book I learned blacksmithing in. In this method i do not temper the blade Looks like you are off to a great start!! I really like file knives. Tempering is what is done to steel that has been hardened and will make the steel softer and less I need a little help tempering my knife made from a 1095 file. Why did the temper, even extreme to the point of allowing file to bite, not work? I might think heat treat went wrong, for example I've ground down some files into really brittle knives before, but my question is about re-tempering. 1. We will also answer why to harden and anneal a knife As per my understanding, since a file is a mystery steel you would first want to soften it by normalizing it in your forge (Bring it to around 870°C and air cool). The first knife was forged and heat treated, the second was ground and tempered twice at 400 degrees +- 5 I just started making file knives from old Nicholson steel files and have read about two different approaches to heat treatment. We will also answer why to harden and anneal a knife Read through our steel forging and tempering chart to learn how to properly heat treat a knife blade and build up its hardness to give it a higher sharpness retention. I give you 4 steps to heat treating, which include : Normalizing, heating, quenching and tempering your diy knife. kny, mep, qtv, zsk, uxg, wkc, gpo, uzo, nmg, qbb, yzx, zbt, mvs, hes, vej,
