Nicholson Files

[BOB HILL]

I tried the chalk trick for a while. In our humid climate, the chalk holds moisture and would cause rust if left on the file.

Yes, I don't chalk files either.  I tried it a few times (because the books said to) and it gave no benefit.  Flattened copper or brass (suppositories) are great for cleaning.  Vinegar for re-sharpening.

Since learning the vinegar trick, I buy most all "worn out dirty" USA Nicholsons I find. And I don't see any funkelnagelneu files in my future (save the Pferds I get for saw chains, because they "migrate" from my truck).

Fresh file on clean steel is a good thing!

I recently purchased a Nicholson patternmakers file with Brazil on it. I have used these files for years and this one stamped Brasí is just as good as my others stamped USA.

Methinks there was a comment from a tool sharpening fellow repeated on here in some thread not long ago, to the effect that they'd improved since first going to SA production.  I suppose the trick would to be not get any of the "earlier runs" - however long they lasted.  May have been a rasp thread.

Jim Kibler mentions in one of his videos that he is using Bahco files for draw filing.  I had never heard of them. Lee Valley sells them and considering the longevity I'm seeing they are reasonably priced.  I ordered three and have used one extensively and it is still going strong.  It is starting to show a little modest shine but cuts aggressively and cleanly.

I used chalk for a bit but could never discern any advantage to it.  Sharply tapping one of the front corners of the file frequently on the vise to clear chips is the best way I have found to clean the file surface to prevent galling of the workpiece from an errant chip.

I've never really had any issues with Nicholson's.  The American #49 and #50 also dulled after heavy use too especially on black walnut.  Thin shelled walnut I've found to be more forgiving on files, rasps and abrasive papers.

I've also had good longevity with Grobet files.

Should have also mentioned that not touching your file surface or work piece surface is a sure way to give you better file/work piece interaction with out the human grease that is always present on your hands.
