How do I cut my climbing rope?

Is the sheath of your rope starting to slip or do you want to cut it into several lengths? Here are our recommendations for cutting your rope.

Indoor and Outdoor Climbing

If you cut the rope due to wear such as sheath slippage at the ends for example, make sure the rest of the rope is intact and cut the rope at least 10 centimeters from the damaged area.

Preferably, use a hot knife to obtain a neat, clean cut.

If you don't have a hot knife, you can use a knife like the SPATHA and a lighter.

 

Mark where you want to make the cut using athletic tape. Cut the rope. If you used a knife, use the lighter to slightly burn the end of the rope in order to help prevent the rope from fraying.

Warning, if your rope has a middle mark, check that it is still accurate.

Check the accuracy of the middle mark by following the procedure below.

 

 

If the difference in length of L is more than 60 cm (UIAA requirement), then cut the other end of the rope.

When cutting a rope, you must mark each end with the proper end-markings.

At a minimum, you must mark the diameter, the new length, and the rope's identifier on each new rope. Use the dedicated tags to do this or mark the tape used for the cut.
