After reading Popular Woodworking Magazine review of the saw, I was confused about their model having detents in the adjusting swivel for both 0, and 45 degrees. I see one external detent holding the zero position on mine below but there does not appear to be any visible detents in any other position. I do sense a tactile click within the swivel mechanism when i turn the front barrel clockwise (facing saw handle aimed away from me). I dont sense the same click when I turn the other direction (which happens to be the direction I would want to use most of the time when removing waste from dovetails). It might be that the mechanism relies on friction alone to hold the blade in this position, I don't know:
Thanks Lee for your response below. So, it turns out that friction alone is enough to keep the blade tensioned in the slanted position.
Anyway the saw is a joy to use and very light weight; surprising how light compared to the cheap Bahco steel coping saw I'd been using. The cam tensioner is also a joy to use. I found the cuts I made in 3/8" poplar very clean.
I was going to do a side-by-side comparison of how the two things cut out waste between some practice dovetails, but In my ham-fisted zeal, I managed to snap the fret saw blade. I think I know why: First I was using a very thin razor saw for my dovetails which leaves a skinny kerf to begin with. Then, I wiggled the fret saw blade into the kerf, rotated the saw and THEN tried to start. I really should have started the sawing motion AS i was rotating the saw when operating in such a fine kerf..beginner mistake, i think.
