Really liked these clamps, perfect for a variety of jobs. Different wood thickness. Holds things while drilling and gluing. The only problem is that the spring in them is very tight. I'm pretty strong, but still sometimes I had to use two hands. This is both bad and good. This is good because it means they keep the wood stuck where you want it. Bad because it can be a little awkward to open the clip just enough to use it. Now they stay in my tool box.
