first of all thanks again to all
this is a "small" idea that I would still develop
for the opening using the heel (do not know if it's the right term) of the blade
maybe a flipper is too bulky
if I can I would like to "frame lock" but I would do keep him the most essential and minimal as possible
a clip, maybe money brings or just to stick where you want and forget it until you need
Now that is GENIUS!!!! Nicely done! I can see that mass produced by one of the big knife company's, CRKT comes to mind first, its right in their genre!
