I have gotten asked in the past for knives made from files. I finally got around to buying a mixed lot of old files. The first one I worked was an old Lennox file marked "for stainless". I heated to non magnetic, quenced in my version of "Goddards Goop" tempered at 400f. It wouldn't get sharp. I dropped it on its tip, it left a divot with the very end of the tip being left in the concrete. Thinking I made a mistake I annealed it and repeated the process this time quenching in oil and tempered at 375F with the same results. It acts like 1070, what edge it takes it looses with little effort. I forged a blade from a large Lennox file that wasn't marked "for stainless", it took a better edge but I haven't finished testing it yet. I've had good results from Nicolson files, they make excellent knives. I just took one I made from a Simmonds out of temper, it warped so I'll have to take it back down and redo it. Anyway, has any of you guy ever had experiance with Lennox files? If so, what results compaired with Nicolson?
