The edges are well designed for a variety of body parts and there are no sharp edges to the metal and zero chance of cutting yourself or others. It scrapes the muscle without tearing up the skin. It's got a decent heft to it and doesn't bend even under the hardest normal pressure and so it should last a lifetime or more. I'll lose it or have it stolen before I have to order another one.The carrying case is functional but nothing that will take abuse. Use it to store it, not carry it in your pocket.The price is about what I expected. Pretty expensive for the actual materials that go into it but it's in line with other similar scrapers and for a generally superior design.The best part of it is that the product works. I recommend watching some YouTube videos to give you an idea how muscle scraping works and be sure to drag the unit toward the handle rather than push it like a knife. I've only had it a few weeks now but it has seriously helped in some surgical recovery and breaking up a few adhesions.
