I love the Case Mini Blackhorn, but they use 420HC. It'd be wonderful if they did a run in CV.
There are a couple knives that I've been pretty impressed with. One is the Sanrenmu 681 or 6040. These knives are identical to each other, don't know why they use two different model numbers. 8cr13mov blade with high hollow grind and a nice clip point. While similar in size to the Gerber, they are quite refined, a lockback with liners, frn handles, a removable pocket clip, and thumb studs. It squeezes a lot of blade in a small closed package and even has a stop pin that prevents blade slap when closed. It really is a fantastic knife worth several times its price.
An outside possibility , constructed very similarly to the Gerber, is the Klein Tools 44002 lockback. Linerless molded frn handle with rubbery inserts, with spear point AUS-8 blade and reversable/removable thumb stud, no pocket clips. Made in Japan. Don't know who makes it, though it does have a great resemblance to a Moki model that didn't seem to have much availability in the US. This knife is a little larger than the Gerber.
