I've had a box of these for quite a while and I'm always finding new uses for them.  They are real handy to hold stop blocks on your radial arm saw fence, drill press fence and table saw miter gauge fence.  I hold projects  together during "dry assembly" and while tracing parts for  reproduction.  You can clip a note or plan on anything the jaw will  stradle.  Did I mention gluing?  They're just a little too tight to use for  a nose clamp when you're working around Ralph after he had those beans for  lunch, but you should use a respirator, anyway.
