I bought these to cut thick leather for knife sheaths. I'm not sure how thick the leather I'm cutting is, but it's tough saddle leather, about two cents thick. They cut very well against the skin and I chose them after looking at reviews of both more expensive and less expensive brands. I really like them, they cut well, are comfortable and seem to be durable. I haven't tried them on other materials but I believe they can cut anything but metal no matter how thin sheet copper should work.
