Mann Lake has a new product: Uncapping Punch.

It looks like a short paint roller with lots of little spikes on it. Has anybody used anything like this?

I've harvested for only one year so far, and used a pair of non-powered uncapping knives (heated in water). I need something better I've read varying reviews of uncapping planes and electric knives, but haven't seen the roller punch before...

Thanks!
