クワガタ

Never thought I'd get excited about a canister puncturer, but the claw-shaped head on this thing is genius—it hooks right onto the valve and vents the leftover gas out in seconds, saving me from tossing half-full fuel cans.

I was a bit skeptical about the beetle shape, but the claw really grabs those canister valves tightly without slipping. Finally emptied three half-used fuel cans in under a minute each.

The claw head fit perfectly onto every canister I tried, no slipping or struggling. Took maybe five seconds per puncture to drain the fuel completely.
