Japanese craftsmen call the shoulder of a tenon "dozuki".
Although a good dozuki saw can be used for any fine work, it is particularly useful for dovetails and tenons where accuracy and a smooth cut are so important. The 0.011" thick blade with 25 tpi cuts quickly and leaves a clean, crisp 0.016" kerf in both hardwoods and softwoods.
The teeth have little set but, because of the patented cutting rakers, they still cut quickly. The solid brass back gives the saw rigidity and enough weight to allow the user to concentrate on the line, not cutting pressure.
Ideally balanced for fine work; it is 21" long with a 9" blade. A replacement blade that includes the brass back is available. For anyone who enjoys woodworking, this saw will quickly become indispensable.
