Ostap Hel’s wedge is 1.70 inches long, 0.18 thick, and weighs 0.29 of an ounce — small enough to ride on a keyring without announcing itself, thick enough along the spine to pry, scrape, lift a can tab and turn a flat-blade screw. The oversized lanyard hole is the quiet decision: it takes a split ring directly, with no fiddly loop of cord in between. $27, in grey, purple or champagne.
