Topic tags/keywords: fret saw blade

Hi folks, I’m researching fret saws for cutting out dovetail waste and had a question: my dovetail saw leaves a very fine kerf, 0.010”. What thickness blade for a fret saw blade would you recommend? Or is that kerf too thin to get a good blade through the cut to reach the baseline without damaging the blade too easily?

It doesn’t matter a lot. You may scratch the kerfs getting
the fret saw in there, but it won’t be enough to mess
up the fit. Thin blades, front to back, break easier. At
some point you have to go pinless and use a jeweler’s
saw but then there are a lot of teeth and the process
gets slowed down.

You may want to email or call a vendor like I have the LN thin kerf dovetail, and they let me know if the blade in question would work. Or you could check with someone like They might be able to help. I know that Ben’s sells a Pégas ultra thin blade 0.0076 thickness which might work. (no affiliation to either location). Pégas is often recommend for use with the Knew Concepts saw. Is your saw a Japanese saw?

Thanks folks. LRR – yeah, it’s the new Lee Valley super fine dozuki. I’ll send those vendors an email to see what they recommend, thanks again.
