The Weird Reason What Cast Saw Does To Your Skin
16Ever wondered why that cast saw makes your skin feel weird? Watch this video to find out the strange reason behind the sensation!
Here’s what happens if you accidentally come into contact with a cast saw. Cast saw blades are incredibly fast and sharp, easily cutting through tough materials like plaster casts and even wood. But have you ever wondered why they don’t cut human skin? The secret lies in the blade’s movement—it doesn’t spin like a typical saw. Instead, it oscillates back and forth within a tiny range, about three millimeters. Because human skin is flexible and soft, it moves with the blade's oscillations rather than resisting, which prevents cuts. This makes cast saws both highly effective and safe for removing casts without injuring the skin underneath.
