This saw is a standard. I have one and it works just fine for most dovetails work. It is easy to control and doesn't cost too much.
These small saws provide control for cutting dovetails, small joints, cutoffs, and other shop tasks.
Straight Backsaw Stained European beech handle, 8-1/16" Sheffield steel blade has 17 TPI, 1-3/4" depth of cut and .040 kerf. UK.
