Guess everyone has THF's knives?

A LS buddy of mine was camping Sozu, and there was no one around during the pop... how nice that everyone who wants Thief's Knife on Bismarck already has one! Did 4 Kirins last night, got 2 Shining Cloths, 3 Osodes, 2 Kirin's Poles, D Body and N Body. 0/4 on W Legs... stupid manticore.
