Title: Good for spot filing, but dulls quickly
Review: The fret crowning file was easy to use, but I found that it dulled very quickly - I could not completely crown the frets on my guitar neck with this tool. The guitar in question is an epiphone from the 90s, and had badly worn frets - but the fret wire was nothing exotic. I leveled the frets (a bit of work), then began crowning them with this tool (a lot of work). But this file was essentially worn out after 7 frets had been crowned. So I need to order a different file.I know that this file cuts in only one direction, and is not as expensive as the diamond files - consequently my expectations were calibrated for hobby-level use. But nevertheless the file should stand up to a complete set of frets before wearing down.
