Not sure, this is the most info i have found on them outside the few posts in this thread. They are not the light blue stainless that are currently available.
Pic shows up small, ill link to it when i hit 5 posts
Thanks. And yeah japan does still make a blue handle/diamond tip, but i believe these are the discontinued rocko line.
I have a link to the old brochure but cant post until 5 posts.
Saw these at a pawn shop here in japan. I found information here as to why they are not green like usual, so i thought I’d share. I thought it was pretty cool they were still in the box!
