How to cut sorbothane?


I recently read a glowing review of Herbie's Big Fat Discs, which are 5/16" thick by 1 5/16" diameter sorbothane discs. So, I did some research and I found a huge variety of sorbothane sheets available at McMaster-Carr. I bought a 12"x12" by 1/4" sheet of 40 durometer sorbothane for $29.

Does anyone have a clever and easy method for cutting discs out of this sheet other than scissors? I was thinking of a sharpened cookie cutter type thing as a tool which could be hammered down on the sorbothane, effectively cuttting a disc...

BTW, I can get 8 discs out of this $29 12"x12" sheet (with useful scrap left over), and 8 Herbie's Big Fat Discs would cost just under $90.

If you're handy at all you might visit Home Depot and buy a piece of pipe
of the appropriate diameter and then grind the end so that it has a sharp
edge. Or you could buy a cookie cutter and sharpen its edge.

Both options I had considered.

Ironically, once I've gone to HD, purchased the pipe, sharpened the
edge, I'd probably have been better off buying some pre-cut sorbothane
discs on E-Bay! :)

Probably, I'll cut 1 1/2" squares. No need for discs as far as I can tell. I'm
going to place them between the upper and lower cabinets of my VR4
loudspeakers, so they won't be seen anyway.
It's not easy.

I tried a model knife and sciccors, but they came out a little rough.
I'd be tempted to try a cookie cutter, a piece of wood and a woodworking G clamp, and leave it clamped overnight to see if it cuts through.

I have no idea if it would work, though.

If it does work you could make them in the shape of gingerbread men !

I wonder if gingerbread men would sound better than X-mas trees?
Sharp edge of a tin can? Seems also there is a leather working tool that cuts circles. Is Tandy leathercraft still in business?
