I bought these to make picture frames. No sharp plastic edges. The springs are stronger than I expected, but that's a plus. It came with extra/interchangeable guards. They have a horizontally sliding head that allows you to hold two parts of different sizes. Haven't tried them yet but the price was worth buying to try them. I hope they prove more durable than they seem.
