Would recommend this one for sure. It's probably bigger than what most people are used to carrying, but I wouldn't consider it "over-sized". I think the blade is 3.5"

I have an allegedly genuine one of these. It's really not all that large, it is a bit on the heavy side though.

It has 2 real problems.

1. The clip is the usual cold steel pile of shit.
2. The lock is very awkward to use and not very interesting. Half the time your palm stops the lock from opening to engage, and the blade rebounds. Then should you get the knife open, it takes a lot of force to pull the lock open - and your finger may get caught under it. This is a two handed closer if you like your blood on the inside.

I have no idea how the same chap came up with the shark lock and whatever the fuck this scorpion lock is.
