I usually just use 2 pair of pliers to remove the roller ( just kidding  )  I want one,I have an adjustable free standing one. But i really like the little bradux tool that nips under the roller with two tapered jaws that lift it off. You can get under a scope with it to see in detail how the job is going. There is some technique involved to stop you chopping the staff, doesn't particularly matter if the staff is already broken but it naffs up the tool's jaws if you crunch the staff, and the jaws need to be in good shape to prevent damaging the roller. But well worth a try if you've never used one and you can find one that hasn't been misused or buy a one new. The trick is to keep one of your fingers between the two arms to soften the squeeze, with a little practice its a handy little to. I will now prepare myself for an onslaught of negative feedback on it

I'd like one of those for my staking set. 

I bought a cheap roller remover, thinking I could just file the jaws down so that it worked well. It didn't, so I ended up buying the Bergeon version, which does work well. Though, as @Neverenoughwatches points out, you do have to be careful not to damage the roller of staff. Rollers are very soft and easily bent whilst trying to remove or refit.

I'm sure i tried the same with some cheap ones, its nigh impossible to get in to sharpen them , best bet is to buy new and look after them.
