Hitting stuff with a hammer works well.
In that sort of situation, I tend to use a toeclip strap. I haven't used toeclips for decades but I make sure that I have a few straps available. I sometimes use one as a front parking brake and I usually cinch one around my cape to stop it unrolling. They can come in handy in non-bike applications too.A length of bootlace or sash cord can be useful for restraining a stubborn Schwalbe Marathon at one point when trying to fit to a wheel without resorting to the use of tyre levers. Cable straps also work just so long as you have cutters to hand afterwards.
Better stick to opening beer bottles with them thenMy buttocks, as firm and tight as they may be, are not strong enough to crimp on a cable end.
I carry a pair of latex gloves in my saddle pack for fetttling/tyre changing on the road - I discovered today that they can be used as emergency waterproof phone covers, although the powder does maks a bit of a mess!
