erickongThe Kraken looks great for butterflying shrimp. The shucker I would avoid though. 10% of oysters will be a pain to open and if you accidentally slip, the bottle opener will not be friendly. Referring to the shucking video I suggest always wearing a glove on the hand holding the oyster even without the bottle opener I've seen pros get a nice gash while opening. That oyster looks like it has been worked a bit already as well. The joint shows definite wear on it.
