I have never seen mass-produced saws that overcome this by side-grinding hardwood. It is straight and skin is beautiful. Although it is written as Vertical grinding, it is not as comfortable as horizontal grinding. Vertically grounded exclusive blades are safer. We would like to release a special grinding blade for hard wood.
It can be cut loosely lightly with the pitch equivalent to the ninth dimension to the blade thickness equivalent to the eighth dimension, the replacement blade is also inexpensive and used as the main saw. However, compared with double-edged saws, vertical grinding of hardwood is somewhat tiresome (sideways ground is no problem).
