Saw that doesn't cut your skin

Wait—how can a cast saw slice through hard fiberglass… but not your skin? 🪚🩹 Watch the demo that freaks everyone out at first, then makes perfect sense. The secret isn’t magic—it’s motion: the blade vibrates (oscillates) instead of spinning, so it chews through rigid materials but glides over soft, flexible skin. See the balloon test, the paper trick, and the slow-mo close-ups that show why it works. Ever had a cast removed—did it scare you or feel oddly satisfying? Tell us in the comments!
