I kicked up another thread that mentioned it was a Kershaw with a gut hook, and he was using the hook to cut the twine. I only found one folding model with a hook, and it looks like the user's fingers would be wrapped around the lockback release bar if holding the knife upside down.

I grew up with slip joints, and still treat lockbacks with the same respect. For me it's the same as never using/trusting the safety on a firearm.


Socialism is a philosophy of failure, the creed of ignorance, and the gospel of envy, its inherent virtue is the equal sharing of misery.
