A sharp and properly set saw is an amazing tool and correct setting of the teeth makes a world of difference. The "set" of a saw blade refers to the amount of clearance the saw teeth have over the width of the saw blade. If the set is not even, the saw will not cut straight. The fastest, most accurate and importantly consistent method of setting is to use saw setting pliers. Somax produce two models, the gold handled one for regular 4 to 12tpi saws, and a finer blue one for 12 to 26tpi saws. The blue saw set has a much narrower plunger to take into account the smaller teeth. By unscrewing the knurled knob you can turn the scaled ring (which is the anvil onto which the teeth are pressed) until the desired pitch appears. The anvil on the both pliers is marked from 4 to 12, this is not tpi but merely a guide as to the position of the anvil. The amount of set required is easy to judge when the saw is in the jaws, simply make a note of number on the anvil for future use. Use only light pressure when setting the teeth.

Great ToolI was pleased to find a setting tool designed for finer work than my vintage Eclipse solid bronze model but I did not think it would be so much easier to use. I reset my Styles & Brown Victor brand small gents saw, that I had ruined by over zealous use of a stone to improve its run, what a difference. This saw now runs true and very, very smooth. So I turned to an old Spear & Jackson tenon saw that I had rescued from a skip brown with rust but I still could not bear to dump it and just setting the teeth made it work again and I am sure that a little work with a very fine file will improve it still more. Highly reccomended.
