I've never messed with a lever lock before, so I wanted to take it apart.

I assume the teeth on the levers are an anti-picking measure. Looks like they'd be pretty damn effective.

4 levers for one key, 6 for the other.

Looks like someone ground the lug off the bolt so it only requires one key. I see the drive lug for the toothed levers is also notched, making our lives even tougher.
