Sharpening pipe wrench jaws

[Bill Houghton]

I have a range of pipe wrenches that I used on the galvanized pipe in our house.  Some of them tend to slip more than others; it's only just now occurred to me that this may mean the jaws are worn.  Can the teeth on pipe wrenches be sharpened by filing?

[Branson]

I've sharpened the teeth on a few, using a sharp saw file.  Seemed to work well.

I have found that the vallys of the teeth fill up a good stiff wire brush works well  bob w

Since I never, or hardly ever, buy new tools, all my pipe wrench jaws came to me dull.
 If they are very bad I use a thin dremel cutoff disk as if it were a tiny angle grinder disk.
 Gets you right in there.
 File to finish of course, but a file barely cuts, so if its very dull, grind first then, the file.

On all the ones I got that I bought to use I have had to file them, I take a triangle shaped file and it usually fits in the groovers perfect if you tilt it a little.
