Basically, the goal would be to discreetly pick up a single coin when I step on it on the ground and to hold onto it while I continue walking.

I already have Sandals I own that have a functional bottle opener on the bottom in the rigid arch cavity of each Sandal;

I'm thinking maybe I could get a cobbler to replace the bottle opener and attach the coin grabber device (that is 3D printed or something) on the bottom or the Sandal instead.

What do you think?
