I bought these and tried them on a couple of frets and they are great but I am not ready to use them. It's a set of 3 sizes (small, medium & jumbo) that are interchageable on the handle--quick and easy to switch! Just $35 shipped USA SOLD!!!! http://m.ebay.com/itm/370652537328?nav=SEARCH&sbk=1 save some $$ today DETAILS: Far more control of the cutting profile than any other file, as we'll illustrate in the photos on the left. 3 different sized (Sm, Med, Jumbo) cutting tips that can be changed in seconds, or replaced if ever needed. A special innovative dog-leg shaped handle for extra clearance when working over the guitar body. It also features a hardwood handle that is shaped with extra finger clearance in mind. No bruised knuckles here! It's just all-around more comfortable to use than any other file. Cutting tips that are razor sharp, heat treated and hardened. You should be able to get years out of these. Stainless frets are not a problem! Cutting tips featuring smooth, radiused front and outside edges. One slip with other fret files (especially some of these snaggle-toothed ones here on eBay) and your fingerboard is scarred for life!
