I'm looking for a heavy duty corner rounder. One that will CLEANLY cut through chipboard, mat board, acrylic etc.

I've searched around and came up with WRM Corner Chomper and the Zutter Round It All. I like that the Chomper comes with 2 for the price of 1, but that would be a bonus-not a decision maker. I'd rather have the 1 that cuts thick stuff cleanly and maybe even on the 1st try

Have you tried either of them? Which do you think is better? Pros? Cons? Comments? Suggestions?!

Thanks - and happy Friday Eve!!
