I imagine a compass with a pen knife blade instead of the pencil portion might work...never tried it, so I'm not sure...
Best of luck!

Jon, The tube method is great for small diameter discs, but for half centimetre or larger, the best tool is a 'compass cutter'. This is a tool with an arm projecting from the centre spindle, along which a blade attachment can be slid. This is set to the correct distance to form the circumference cut edge. Here in the UK a brand called Olfa is commonly found in model shops and also ( I was surprised too....) dressmakers' shops. One tip I can offer to avoid a pinhole in the centre of the disc, is to use paper glue to attach a base of 40 thou card to mount the centre spindle needle into. You won't need to apply much pressure to cut foil with a new blade, and the pin won't penetrate the plastic to mark the centre. Good luck, Chek
Would expect you'd need a knife with a swiveling blade - X-Acto makes one - and a circle template.
Yes - got one of these; a drop-point bow compass, with a blade attachment for the drop.
I have never had to cut a circle in foil yet, but I do use a Olfa knife for all my foil cutting. I don't know the model number but its the one with the balanced yellow tubular handle and rubber grip. The blades are the best for foil cutting, I've ever used and hold their edge much longer than an X-Acto. Believe me, when they are new, they are so sharp, they are absolutely dangerous! Mike IPMS
