Knives really aren't good self defence tools. Without training they are as dangerous to the wielder as to the attacker. Even with training running away is usually a better tactic.

Depending on jurisdiction carrying a knife as a (defensive or offensive) weapon may be illegal. There may also be restrictions on length, foldability, automaticity and concealability to carry a knife as a tool for no particular reason.

Are you aware of their local restrictions? If you let us know we can better advise.

I'm almost 100% in agreement with this review, especially on what a useless fucker the scorpion lock is if you actually want to transition between locked and unlocked states.

The only bit I differ on is that the AD-15 is not the widest closed knife I own, but only because I have a Cold Steel 5-max.

Shrug what China is doing to the US, the US did to the UK, and we did to, well lots of places.

Just the way of the world.

D2/K110 doesn't have the corrosion resistance I prefer (and 440C doesn't do to well either as a barely stainless steel). A week in my work trouser pocket is enough to get rust specks on D2.

I'm a big fan of ganzo's work, but their low end blade steel is an issue for me. It doesn't need a supersteel but a better budget to mid range steel option would really make their line-up more desirable. For £10-£15 more I'd snap this up in 14C28N or 154CM.

Maybe a CJRB Pyrite mini? The blade is just over 2" but otherwise suits your requirements.

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.

Partly it's legal, UK law no longer distinguishes between automatic and assisted opening.

When you get one that wasn't declared by the (usually chinese) retailer and remove the spring, to avoid being arrested for owning a flick knife, the detent is usually so weak due to reliance on the spring that you risk arrest for owning a gravity knife.

They are also really unpleasant in action, sometimes dangerous. I once ordered a cheap knife to see if I liked the wave style opener. Turned out when it arrived that it was also an assisted opener - the wave would catch your pocket and the spring would launch the knife towards your armpit. I actually destroyed that one as a service to humanity.

I was absolutely sold on needing one of these, until you mentioned the spring assist.

I too would appreciate a familiar object for scale.
