Reason Why A Cast Saw Doesn’t Cut You!

Have you ever wondered why a cast saw won’t cut you, but cuts a cast easily? It might look like it could cause a lot of damage, but a cast saw is designed with a sharp blade that rapidly moves back and forth over a very small angle to cut material. This is different to a normal saw, which has a rotating blade. A cast saw needs something hard and resistance to cut. If it comes into contact with something soft like skin, there is not enough resistance and the saw will not be able to cut through.
