Got one just like it in a grommet kit. Like the grommets for installing in a tarp or any number of things in order to put a ring, tie down, snap (as in leather) etc. This is the hole punch that you start with.
Yes it is, I absolutely love it. Several of us on the keypicking forum gave our ideas when Sparrows was designing the mats, and they were nice enough to send us each a free one!
