Michael Sherril's own words:
I have used shure form tools on clay since the first time I saw them at the hardware store, but it did not take me long to realize that the handle did not function well with clay. It would easily clog and then frustrate the user. So, my answer was to design my own handle.
The shredder handle is the production version of one that I have used for over ten years. It is one of the most useful and handy tools in my box. I hope you love it as much as I love mine.
