Use a bearing seperator/puller if you wish to salvage the crank arm. It will do the least amount of damage, if any.
You'll have problems getting that behind many cranks. I've seen people use a universal 2/3 leg puller, but the problem with those is stopping the hooks from slipping off. You could maybe cut a C-shaped piece of steel plate to slip over the axle, and use a puller on that.

Yea, the three jaw pullers are difficult to use on cranks unless the rear of the crank arm is cut square, instead of being rounded. I don't know any off hand that aren't rounded. The bearing puller actually works a bit better, and in many cases actually fit more easily behind a crank. They make different sizes. They require less room behind the crank arm than a three arm puller does.
