Pi Knives has introduced an interesting folder design they call the aX – dobolock. Debuting, and winning an award, at the 2011 Blade Show last month, the knife opens toward the palm. Er, it folds along a different axis. Uhm, maybe it’d be better if you just watched the video.
Interesting? Sure. Useful? Hard to say. I can see where the lock would be very positive and secure. I can also see how a lock failure would direct the blade to the side, instead of delivering the cutting edge into the hand. What’s your opinion?
