Must get it from my father too. He did everything from biochemistry to rebuilding carburators to building houses and now making fine furniture. Also an engineer, i built several 1911s, ars and precision rifles, fixed a bunch of problems with my smith and wesson 500. And did a few things on my saaThe one thing i will not do is mess around inside my 84 colt python.

Reading some of the above reminds me of an old timer that I worked with and taught me many things. He used to say.....it’s more important to know what you don’t know, than to talk about what you do know. It also reminds me of Inspector Harry Callahan....a man’s got to know his limitations !
You are correct that a lot of the current files a case hardened.
Currently the claim is the Nicholson files are still made of 1095 same as a lot of the automotive leaf springs. 1095 has been the mainstay for spring steel and or files forever. For files the heat treatment is full hard.
At one time Nicholson also used W1 steel. I only owned a couple of files that I believed to be made W1. They are the best files I have owned. For springs making 1095 or 1075 is a better choice.
Not sure when Nicholson went exclusively to 1095 but I do know with both Nicholson and Simonds files the quality of the material has been going downhill since the 80's. I still have and use files from that era and before. They seem to last almost forever with proper care. Today's premium files not so much. There is a significant difference in performance with both Nicholson and Simonds since they moved production offshore. It may still be 1095 but it's not the same quality as the older product. That is not uncommon with foreign steels. Newer post 2010 Nicholsons are made in Mexico or Brazil and are not close to the quality of the older US made Nicholsons.
Currently a lot of the cheaper files are case hardened and not suitable for making things like springs, knives or much else. Even on the more premium files likes Simonds they switched to case hardened steels at least for some of their files. For me that moves them out of the premium category.
On a side note, there are numerous companies that resharpen files. Most use an acid etch but some use an abrasive blast. You can do the acid etch at home using vinegar with a 24-hour soak. Vinegar soaks work well to restore dull files but once chipped or worn to the point you see flats on the crest of the teeth not so much. Proper use of chalk or soapstone and a file card greatly increase a files useful lifespan.
Currently Grobets brand files seems to be the best available. I have heard good things about Pferd brand, but I have never used them.
The last Nicholsons that I purchased were NOS US made long angle lathe files. I prefer them for draw filing.

Thanks for the info. I have several boxes of used files that came from a saw mill. Have not bought a file in the last 20 years. Did notice that if a file is used on steel it does not want to cut brass. I probably wear out most of the ones I have by using them on the lathe.
