Yeah on that file business .FWIW the very best hunting knife I ever owned was made from a repurposed file that came from Solgen Germany .It would hold an edge like a razor .My dear old dad lost it some place on the side of a mountain in Colorado.
An oven with a "soak heat " is probabley the best method of annealing but there are others .One is to flame it up to about 1400 degrees in a forge then toss it in a bucket of powdered lime .It will still be hot to the touch after about two days .
Then again it depends on the file .Some are so brittle just dropping them will break them .Some like a black smiths hoof rasp you could probabaly use for a hammer .
Often times you can find heavy old files at flea markets etc for next to nothing .
