Homebrew PCBs

I bought a paper cutter from Office Depot for about $30, but it has a
blade that is less then 1/16 inch thick. I tried to cut some 1/16
thick FR4, but I wasn't willing to apply enough force to actually
start the cut. I was afraid it would ruin the cutter.

I just picked up another paper cutter, this time from Harbor Freight.
It was on sale for $13, regular price is about $20. This has a 6mm
thick blade, much sturdier. I had no trouble cutting some 1/16 thick
FR4 with it. It produced a straight, reasonably smooth edge.

The latter paper cutter looks similar to a cutter that I saw used in a
university's prototype PCB shop.
