Yeah, i figured that. Has to be a frame lock with ass. opening. Rainbow is kinda similar in looks, I guess.
Do Leeks have a small flipper?
I'm not sure what the coating/anodizing on the Pink Leek is, but I know from ownership that the Rainbow Leek's finish is very tough. The one I had was the most expensive knife I'd owned for many years (previously owning cheaper Kershaws or CRKTs), and I used the hell out of it before giving it to a friend. The finish held up way better than the edge did, with lots of resharpening to the soft 440A blade wearing it quite a bit..
The other cool thing about the rainbow coated knives is that every single one is unique. The process involved makes a similar coloring, but no two are identical.
Except for the type of lock and handle/liner materials, all the Leeks have identical blades (except the Random Leek of course), and identically shaped handles.
The flipper isn't huge, but it isn't difficult to engage either. I never accidentally engaged the flipper when putting my hand into my pocket for other things (pen, cellphone), nor did I ever wish it was larger.
If you're looking for a non-threatening looking knife, or perhaps one to be carried by the fairer sex, I'd go with the rainbow coated one. Tougher finish, and stronger lock.
