This is well designed and does an excellent job of rounding and polishing fret tops.

After 50 years of playing guitars, a couple of years ago at age 60 I started a small setup, maintenance, repair business. 60 year old hands (well mine anyway) don't enjoy the death grip that fret polishing normally requires. This is a genuinely useful tool for me - has cut the time and strain required for great fret polishes. It's expensive, but for me, definitely worth it.

just got the plexiglass no emery paper or whatever is shown in the pictures.. any idea of what to use?
appears to be well made, have nothing to to use with it to try it out

The "Perfect Fret Finisher" for the perfect fret job! Wonderful concept and solid material!

Do you ever sand your frets? Are your fingertips aching under the strain of reaching to the edges of the frets? Do you want a Thingie to help do that thing? Then this Thingie thing is for you. I know it is for me!

Does a great job of final shaping and polishing frets like nothing I've ever used. Fits the fret wire I use most perfectly - other shapes/sizes would be great. Easy on the hands.

Solid simple and functional plus the etching on the side really help hold the sandpaper

Excellent tool for everyday use. Slightly expensive for what it is. 6061 Aluminum would justify the cost. For now it saves my fingertips, so be it.

This product is great. It hits the entire fret in a second. Just need to lay a bit of tape down to protect the wood, and away you go. What a great invention. Wish I would have had this years ago. Thanks!!

Used it for the first time yesterday, couldn't be happier. Yes, it's kinda spendy, but it saves my thumbs from getting sore, cuts down on time spent polishing, and produces better results.So, I'm happy to ante up. Thanks.
