- Fid
A fid is a conical tool made of wood or bone. It is used to work with
rope andcanvas inmarlinespike seamanship . A fid differs from amarlinspike in material and purpose. A marlinespike is used in working with wire rope, may be used to open shackles, and is made of metal. A fid is used to hold open knots and holes in canvas. A fid is used to open the "lays", or strands of rope, synthetic or natural, forsplicing said line.A "fid" is also a unit of measurement equaling approximately 21 or 22 times the rope's diameter. The fid is further divided into a "short" fid and a "long" fid. A short fid is 1/3 the length of the full fid and a long fid is 2/3 the length of the full fid.
This chart shows examples of short, long, and full fid lengths for ropes of almost all diameters.
