Okay the presentation in the video is pretty hard to take. Music is too loud, the guy is downright obnoxious.
These pneumatic Wolverine claws that go both in and out... and spark if you run them against each other. Those are really cool.
Sure they're bulkier than the real Wolverine's claws and... you know... they're don't go under the skin... and they aren't made of a fictional indestructible metal. But I think we can give a pass on those details because they are entirely functional as designed.
Good god though man... calm down. Meditate or something.
