The arkansas edge has staying power that the crox edge doesn't. Same with a good jnat, it's as easy to shave with as a crox edge, less harsh and with a good linen, it never needs to go back.

Crox is like a chiropractor. You feel better for a little bit, but you're going back to it too often if you start to rely on it.

The trans/black ark edge is more like a...... vasectomy? Extremely useful and works for a long time!
