We use an old paper cutter (the big heavy kind without safety guard) I got
at a garage sale ($3 bucks) we put a razor edge on it and can make 1.5 inch
straight cuts in most innertube all day long.  Each cylinder gets three
bands. When the gear is washed off the bands get washed too. When they get
old and cruddy -- throw them out and put new ones on. Keep a mess of them
in your gear box too someone always shows up with surgical tubing and needs
to be corrected, better to just give them three bands then to try to
explain the rational -- they get the point pretty quickly.
