seat foam cutting tool you may already own

Ok after riding Les bike while I was up there I have been planning on cutting
my seat down and contouring it and I remembered back in the day (the 80"s) when
I did uphostery I used an electric knife I got at a yard sale to cut foam

Good old ebay 16.00 delivered to the house

in less than a minute cut out up an old seat foam from a moped
works better than I remember lol for tou guys building your own seats this is a must have
after you make your seat you can still carve a roast or turkey at the holidays









Will be pulling my seat off in the morning and taking it with me
cant decide whether ti stay with smmoth viny or try a design

And very easy way to shape it:
