Will this tool work for stainless steel frets?

Yes. It will just take more elbow grease on your end, and wear out the tool faster

Will it work on low narrow frets on mandolins

Hello Richard, Depending on how narrow your mandolin frets are, this may not be the ideal file for that application. Do you know how wide the frets actually are? The sweet spot for the narrow side of this file is around .080" to .095" + or so. The good news is we have a smaller version of this file in the works.

How long should it last? I've used my 2.0 on about 25-50 necks and it seems dull.

25 to 50 necks? Then It paid for itself eons ago. I've only done 2 necks so far. If it's like my other files then it should last a lifetime. That is, if you keep it clean at all times with a brass brush and chalk. And store it in a dry place. Hope I get 50 necks out it. I'll be doin a stainless fret job soon. True test on that one,

Is it faster to use expedited shipping? Does it come with tracking number?

Yes, if you order the "Seller fulfilled" version (will say Ships from FretGuru / Sold by FretGuru, NOT "Ships from Amazon") and select Expedited, I can personally package it now and get it out the door today (Saturday). You'll get the tracking number. Thanks! Bernie / FretGuru
