I've got a kid in pilot training and I've been thinking of making him a chute knife, OTF type.
Trying to get together some ideas for gravity mechanisms and blade rails.
Any info or links to this subject would be most appreciated.
Honestly the best teacher for you might be an actual knife that you can reverse engineer. Id suggest buying a couple cheapies just to dissect and get an idea of what works. There simply isnt a lot of literature available for such designs.
