Sheet metal nibblers have been around for quite some time. The technology has not changed much. Along with snips, nibblers are an essential tool in every metal worker's toolbox. Though innovations have come from adding air power or electric power, there hasn't been much in the fundamental action of how a nibbler works. Bessey may have just pushed the boundaries with their Super Nibbler. They were kind enough to send a set for evaluation. Though they're not quite ready to completely replace a conventional nibbler, they certainly do augment existing possibilities. I'll let you all decide if they're truly "super". Enjoy.
