I want to taper some of the rubber Be gave me, but I can't find a roll cutter, only found an X-Acto knife. If it's really sharp, would it work?

NO ! short answer, long answer, rubber will tend to stick and fold as you cut with it, the key for roller cutter is an "almost" vertical cut ...

No I will not work, I have tried it however if you really want to try with that, u shud cover the entire piece with tape so it overlaps both sides and both ends then cut, there's a video online, how to cut bands without a roller cutter- check it out.

using anything other than roller cutter will result in a kind of saw teeth edge on your rubber (caused by the blade gripping the rubber until the force cuts through) thus making chances of it failing into your eye all the more possible....

i wouldnt suggest using scissors, but a big pair would give better results than a knife...

i say long as in if you can acurately cut (in 1 snip) your bands from scissors then it in theory would work, with scissors its the multiple snips that cause problems...

you can try a guillotine for cutting paper...

i picked one up for about 4 quid (should have used it yesterday)
just make sure you choose one with rotating blade and not a fixed blade...

i cant think of any better ways of cutting rubber without a rotor cutter...

hope this helps

I agree with Arturo and Joerg. I would strongly recommend investing in a roller cutter if you can get one (they're only about $10 USD in the states, not so sure about Israel). I've tried the sharpest of knives and razors and have had bad results every time. The roller cutter really does the job - no jagged edges, no folding, it just works well. Just don't do what theDaddy187 did and you will be fine.

I scored a roller paper cutter today (I'll post pics when I get home). It's even better than just a hand-held roller cutter.

If you have access to a drill you could sharpen a big washer and turn it into a roll cutter.
Nah. Washers are, for the most part, too thick, not the right metal to hold or take a sharp enough edge. Don't bother. Sorry Piet :)

I think the correct answer would be you can, but a roller is much better. It's the micro and some not-so-micro tears that make a knife cut less durable than a smooth, sharp roller cut. A razor blade would be better than an X-acto blade as it's thinner ad more finely sharpened, but still not as good as rollering.

On a safety note, use a cutting mat. The cutting of bands on your leg can result in serious injury!:D

I was going to do it on my groin, but okay. :)

Before I got a wheel I used a razor blade with pretty good results, the trick is to cut in a tub of water to lubricate the knife blade. I clamped the rubber between two pieces nylon board so the top one was a guide and the bottom served as the mat. It worked ok till I got the right stuff which is ten times easier.
