I was particularly looking for something fixed, something small, something with a single edge and something that was easy to grip that would prevent my hand from slipping down onto the blade. MI knife laws are all kinds of not straightforward. Even after reading a write up that was meant to simplify them, the laws still aren't clear. So I looked for something that played it extra safe: small, single edged. I'm still not certain if the fixed part is questionable, but I want something ready to go, not one that requires an extra step.
I looked at ringed ended knives but they were just far too daggery looking to fit MI laws.
