Announcing the newest addition to my Spyderco Calypso family ... a black FRN PE, ZDP-189 Calypso Jr! I just got the knife from MSCantrell an hour ago. The knife is beautiful. I really like the aesthetics of the laminate line on the blade. Some people have complained about the irregular, wavy line, but I think it adds to the knife - like the pattern in a Damascus steel. I was surprised at just how "grippy" the fish-scale pattern on the handle is. The grip it provides is every bit as good as G-10 (though I think I still prefer G-10). I think the slightly wider handle is actually better than that on the Caly3! Unfortunately, like the Caly3, the forward finger choil is shallow, unlike the deep choil on the UKPK. I suspect that this is simply a constraint of the locking mechanism and can't be helped. My only real gripe with the Caly Jr is the awful clip. Maybe I shouldn't say this, as it is, at least, ambidextrous, but I guess that I've gotten spoiled by the wonderful tip-up wire clip on the Caly3 and UKPK. It's too bad that the knife can't support tip-up carry. I've yet to use the blade enough to really give an opinion on the ZDP, but I think this knife will secure a spot in my EDC rotation, especially since it is lighter (1.9 oz) than either the UKPK (2.4 oz) or the Caly3 (3.0 oz).
