For work, I use a set of Gotoh's nut slotting files. It's the 10-piece set (original recipe) with sharp handles meant for a file holder which I've never obtained. My problem is wear issues. My .013 and .016 are dead smooth, so I might as well be slotting with dental floss. A few questions regarding nut slotting files:
Are all created equal? Are they all just tool steel with an abrasive edge? From my searching, most people jump to Allparts and say avoid Stewmac? Any validity? Is there a consensus on good ones?
Does anyone notice their files wearing down faster from Graphtech nuts? It's almost all we use for nuts, with a rare bit of corian thrown in. Do the lucky people who use bone have wear problems?
I read that some people put a tooth on feeler gauges, but after trying to re-tooth my .013 file today with a dremel, I found the results dismal.
Am I just crazy(nuts...?) here? Do they, like every other abrasion-loving tool wear out, or do some just have the same ones they've had since they got their training wheels/files? If so, what is the usual life on a set?
Any knowledge would be great.
