Oakum comes from various parts of the oak tree including its leaves, bark and heartwood. Oakum is scraped off a bundle of oak sticks which then has fibers woven into it to produce rope or thread for whatever purpose you would like. The name itself derives from ancient words meaning “to plait together”. This type of cordage was used by sailors who had no other means for stitching their rigging because they were not allowed in port with unsewn ropes at sea.

Oakum is a type of fibre that is used to make ropes or cables. It is made by shredding old hemp fibres and then using them to bind together strands of new hemp fibres. The process can be done in two ways: either by soaking the shredded hemp in water until it swells up, or by boiling the shredded hemp for several hours.
