I've got some 6mm rubber and need to cut a 10mm round hole in it... it's a replacement footstrap for a kiddie loct bike seat.
Can anyone suggest a way of cutting the holes at all? I'm stumped. Any attempt to do it with a knife will no doubt end in jagged edges that will tear.
Heat a bolt of the right size hold in mole grips and melt through?
10mm steel tube, sharpen the end - give it a good whack.
Use the proper tool. A hole punch, like this:

If you don't want to buy any tools just drill a 10mm hole in it.
What gravity-slave said. (But, use one with 10mm written next to it, in pink).
a bit of steel tube of the right size, a vice and a bit of wood.
Sandwich rubber between wood and tube in vice, close vise, pushing tube through rubber cutting nice neat hole. JD.

Have you been talking to Mrs Darcy?
sharpen a 10 mm pipe.
size isn't everything
... she definitely said that, inbetween all the crying
2 pieces of wood, vice and a 10mm drill.
Sandwich the rubber between the 2 pieces of wood in the vice, cranked up nice and tight.
Drill through the wood/rubber/wood (in the right place, obvs), bobs your mother's.
if it's rubber, fold it in half and use a knife, clamp it to make sure it doesn't move when cutting

Of course it is. Are you sure 10mm is big enough for him/her/you to breath through?
A sharp finger nail or oil-based lubricant?
Glock 23 ?
From my tyre slashing days* - dip a sharp knife in diesel and you'll get a very clean cut.
Presumably a thin vegetable oil would do the same job.
I'd imagine an oiled punch would do the job perfectly.

The correct answer is lightly-lubed 10mm [b]hollow[/b] punch. Lay rubber on broad flat wood before driving the punch.
Sharpened tubing seem perfectly reasonable suggestions if not fussed about buying a punch.
Use a proper hole punch, it's no different to making a hole in a leather belt - although my hole punch will probably only go up to about 8mm or so
If you don't have the right kit pop to a cobbler, I'm sure they'll be able to do it for you
