It did its job but it took me a long time to re-crown my leveled frets. Maybe the diamond files are better but they are very expensive.

Perfect for my use.

Works as expected. Leaves a little chatter that is easily polished off with sand paper and steel wool.

I bought the 4490 double edge files for my solid body guitar project. The frets were already installed just needed leveling and crowning after neck set. I used the wooden radius block and the files. I should have bought the fretting kit because it was just a little more than the radius blocks/files. Anyway they were easy to use and got excellent results was able to get 3/64 action with very little rattle.

OK for the Money but top marks to Stewmac.

I first bought the narrow/medium file and it works fine if you clean it after every few strokes. I then bought the medium/wide jumbo fret file and the med jumbo side chattered like crazy and was a nightmare to use. I had a little winge to Stewmac about it and 3 days later there was a brand new complimentary one in the mail box! Expedited shipping USA to New Zealand. Perfect! New one works well. Thanks Stewmac; top score for customer service.
