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.

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?

I would try a roller cutter. M wife has one for cutting material and it cuts about anything I need it to. I think it will cut cleanly because it rolls instead of drags across the surface
