These have been around for a little while in the guise of Ocean Revolution branded pliers, they were pretty pricey - somewhere around the $120US mark I think?
Anyway I was wandering the local tackle store (australia wide franchise that sell some very ordinairy poppers) and came across the same plier branded as Black Magic. Picked them up for $90 after discount, listed at $99. Expensive but seemed ok compared to getting a pair from the states. I first saw them on a trip with Mick - they really are great compared to the Owners I currently use. Aluminium construction, replaceable tungsten cutting blade (easily cuts braid) large and smaller split ring pliers, replaceable jaw - pretty nifty really.
Only gripe would be the casting on the jaw is a little bit pockholed, on the unfinished surface - hopefully the cast integrity os ok though, time will tell.
