Haven't had a chance to use it yet, but like the looks of it and the different blades. looks like it would be good for fine detail work only, which is why i bought it.
To be truthful I'm kinda disappointed with the fret saw. I build mountain dulcimers and use medium/medium fret wire. There is not a blade with that saw that fits the tang width. But it's pretty good to clean up nuts and bridges with...
I bought this for a family member who is building a dulcimer. He said it as very useful and did the job. He sounded very pleased, and is now working on a second and third dulcimer.
I am glad to have this saw in my shop. Only one problem with it. The kerf width (.012) does not allow the installation of a fret tang (.019). I had to make other arrangements. I don't think it should be sold as a fret saw. But handy for a myriad of other uses.
This fret saw worked perfectly for cutting the fret slots in the dulcimer i just finished. The fret wire installed easily and held well in the slots. The saw is also handy for other precise work.
