Tested my new bottle cap buckler the second night set in. A dry pebble rolling off the pallet stack gave me my target. I dropped into an iron stance, thrust my left forearm up, and let the stone slam dead-center into the fluted metal. Clack. Solid ring. The impact barely stung my wrist, and the rubber strap didn't slide an inch. To finish the drill, I drove my right sai straight into a fallen dry acorn husk, pinning it to the soil. Shield holds, blade bites. My night watch is fully operational.
