I have a multiangle guide (the Tools4Boards XACT thing) that I have been pretty happy with for several years, but it is starting to wear out. I've been thinking of replacing it with a dedicated 3 degree guide.
But I'm wondering about clamping methods for files and stones. The traditional spring clamp looks awkward, like it would slip or get in the way. I see several other systems on Terry's site that clamp the file with a screw and a plate: from Toko, Kuu, and SVST.
Does anyone have good or bad things to say about these, or am I worrying needlessly about the spring clamp?
