Why is sharpen not correct? If it is sharped then it will cut piece instantly and will not jamming.

Saw set is the slightly increased thickness of the blade at the cutting edge. This is necessary because if the blade were a constant thickness throughout, the saw would soon bind in the wood being cut due to the friction bearing against the sides of the saw. To overcome this problem, the blade is made slightly wider at the cutting edge by bending every other tooth outward away from the center of the blade. This bending is accomplish with a saw set, a specialized tool made just for this purpose. The increased thickness of the blade at the cutting edge causes the saw to cut a wider kerf than the saw is thick, allowing the saw to cut quickly and efficiently through the work.

Thank you.
