I wouldn't hold your breath on trying to get one, very rare and they command collector prices. Someone was looking for one on the BST and got an offer to sell, but the price was likely in the stratosphere (as would be expected).
Koki is a pretty helpful guy too, he might be able to tell you whether or not he'll ever restock them. FWIW I noticed JKD got some Hattori cowry-x hunting knives in october...
Unfortunately, it is nowhere! Team Hattori, told me that this is the last and will no longer be anyone to sell!I was looking for it about 1.5 years, appealed even to the Japanese-they wrote me that its impossible to get!We have in Russia, but the price is in the stratosphere(3000$)!Try to take who ever used!
