Craft this one where you stand: no bench is involved, only the metal blade, a few frags and a stack of wood. The blade is the whole question. Until a Level 2 bench makes blades from frags and scrap, each one is a barrel drop, and the salvaged sword is waiting for the same drop.
Let the kayak decide. If a coastal run is on tonight's plan, the blade becomes a paddle, which also swings well enough on the beach. If not, the sword gets it and the paddle waits.
Paddles get lost with the boat or looted off a body, so a group that lives on the water learns the blade blueprint early and keeps a spare paddle where the kayak goes in.
