I've been using this chisel for a few weeks now and I couldn't be happier with it. My analysis of this product showed that it's incredibly strong and durable and the diamond tip is perfect for carving and cutting through tough materials. Ive used it on everything from wood to metal and it works effortlessly on all of them. The only downside I can see is that it's a bit on the pricey side, but it's definitely worth the investment..
