Amos digs in his pocket and pulls out his balisong knife. A quick flick of practised fingers and it's open: he shows this to Kamina and shrugs. The blade is roughly five inches, and honestly only useful in close quarters. Amos is very fond of butterfly knives, but he knows their limitations very well. He has a handgun in his packpack, but using a gun in an enclosed place like a tunnel is a damn fine way to lose his hearing...and attract more insects.

"S'all I got. Sorry." It's still better than nothing his supposes.

He flips the handles again, closing the knife, and pockets it before heading down the left-hand turn, moving at a smart pace.
