You don't necessarily need to sharpen them, but they will clog up when you use them a lot. I would suggest you wipe them clean with a soft cloth and perhaps a little alcohol.

Hello List,
 
Do the roughened areas of broaches used for flange bushing need to be sharpened periodically? 
 
I’m in the middle of re-pinning a set of hammer flanges and it seems some of the broaches cut better than the others.  If yes, what’s the best way to sharpen them.  
 
Thanks,
 
David Weiss
