I’ve seen quite a few Foley Belsaw machines but another brand that occasionally pops up during searches is Burr manufacturing. The retoother is a solid machine and I had always wanted one and I recently learned they made a saw filer. I couldn’t believe it, I was asking around for an Acme saw filer and a handsaw friend had a Burr one with a reoother and bars. This filer came out before the Acme one I think and was sold by the same company. Or at least Acme, Burr, and Bemaco were all owned by the same company at one point.
If you’ve seen videos of an acme, the vise moves back and forth and you control the file arm. On the Burr the vise stays stationary and the filer part moves on a track on the back. Very heavy, very sturdy and I’m extremely lucky to have it.
