I bought just the short one... mostly because the longer one was out of stock. But no need, the shorter one worked fine for the entire fretboard on a new build project.

The dry heat from this winter caused one of my acoustic guitar necks to shrink a enough to cause the frets to feel sharp when playing. I was going to take it to a shop and discovered the fret beveling file. It cost less then taking it to the shop and I have it for future uses. It is virtually impossible to damage your guitar so I recommend it to anyone who has this problem and wants to save money.

Like most reviewers, I find this tool terrific for getting a uniform, smooth bevel on the fret ends. But I'm surprised no-one has mentioned its tendency to trap the tiny fret filings in the machined surface of the plastic block which then make fine scratches in the top surface of the fret as the tool is moved back and forth if they are not cleaned off regularly. The scratches can be removed by polishing, but next time I'll try protecting the fret surface with tape before filing.

The bevel edge file puts a nice uniform bevel on the frets and because the angle is set you just have to worry about filing upto the fretboard. The height of the file is set so that it doesn't mark the rest of the guitar. Watch for the file riding over the edge and marking the top of the frets.

The fret beveling file makes getting the right angle on fret ends a snap. It used to take over an hour to get it right with a hand file. Now I can bevel the edges of my fretboards in less than five minutes and be ready to move on. This item saves a lot of time and aggravation.

Great tool but hellishly expensive for what it is. But beats having to refret when you realise your strings keep slipping off the guitar because the angle was too shallow!

Nice, simple tool, well executed. Nice and easy to get consistent results.

This does what it is supposed to. I only wish the file was set at a slightly steeper angle.

A useful tool.

Very easy to use with excellent results. I like it!
