Our Ropes


Rope With Bite stocks two types of rope, both made from synthetic materials designed to blend visually with traditional hemp ropes: Hempex and BiteSP.
Originally designed for halyard and sheet ropes on classic tall ship sailing, synthetic hemp has a natural feel but requires no pre treatment and will soften with use.
Our ropes are hand finished with thistle knots, left with 3cm bare ends that allow for easy manipulation, and prevent any fraying even under heavy load.

Material Differences

Hempex is made from spun polypropylene with a look and feel similar to traditional hemp rope. It is easy to grip and is soft on the hands. It has excellent breaking load, good resistance to abrasion and will not rot.

BiteSP is made with extremely dense fine polyester fibers which are spun under tension resulting in extremely low elongation, so these ropes will maintain their original length even through heavy use. BiteSP is stronger, has a higher melting point, uv resistance and feels softer to the touch than hempex, comparable to cotton.

Safe Rope

However pretty and long lasting it is, if there is an issue, you should never hesitate to cut your rope. If you find yourself in a situation where the person you have tied is in danger and you cut the rope we will replace it for free. Just send us the pieces and let us know what happened through a Rope Incident Report.
