How long does a flat leather short saw usually take?

Flat-skinned saws are generally about 20 cm.

Traditional slingshots are generally stretched in the middle and long distance of 22-24cm, which can meet the stretching distance of 80cm.

The short slingshot is generally related to the individual's height and arm span. If a person's height is about 170 cm and the short pulling distance is 70-80 cm, then the length of the rubber band should be about 17 cm.

The thickness of leather depends on the diameter of steel balls used. Compared with the No.8 ball, the thickness of the leather should be 0.5-0.6, so that the shot beads will not have bad trajectory or handle. The taper of rubber band is generally 20- 12.
