Marlinspike
（重定向自Marlinespike）
Marlinspike (/ˈmɑːrlᵻnspaɪk/; sometimes marlin spike, marlinespike, or the archaic marlingspike/marling-spike) is a tool used in marine ropework. Shaped in the form of a polished metal cone tapered to a rounded or flattened point, they aid in such tasks as unlaying rope for splicing, untying knots, drawing marline tight using a marlinspike hitch, and as a toggle joining ropes under tension in a belaying pin splice.
