This is it opened with the blade up. There is a texture on the G-10 that I've never seen or felt, it provides a lot of grip, deeper grooves than the Peel Ply that Spyderco typically uses. The blade came from the factory at near a 40 degree angle on the edge, I think it came 40 degree as ode to the fixed blade it was designed to be like, I reprofiled it to 30 degree yesterday.
Opened, blade down. Not easy to balance this way, it fell a few times. The notch you're talking about is a bottle opener. The bottle opener doubles as a Wave opener. This knife has some hidden uses. The jimping is said to double as wire strippers. I think the notch under the blade can be used to bend or break wire. It has a big clip, rides pretty low in the pocket but the clip makes it fairly obvious. The clip is actually going up against pretty smooth titanium and it doesn't have too much grip. It is possible that it can slide out of your pocket. To support the lock, because of Lionsteel, it comes a screw that makes it so the lock will not disengage. The lock is very strong and I'm not really sure why anyone would use the screw.
It has a glass breaker on the end and comes with a flat screw to replace the glass breaker if you don't want it.
Has a pretty thick layer of titanium for the lock bar and a very skeletonized layer of what I think is titanium to support the G-10, I like how the skeletonized side is. I'll talk about that in the next picture.
This is a picture of how the G-10 scale is supported. It's one big hole in the liner, which can bend some, but I think the G-10 side is supposed to bend some, so I like how this feels.
