2mm cord cuts through 9mm climbing rope

You don't need a knife to cut a climbing rope. Some thin cord and friction does the job pretty well.

Very cool and eye-opening!

Any chance we can see the results of 3mm and 4mm cord?

I'm looking to use 'bank line' instead of paracord, to carry accessories while I climb. A standard paracord size is 6mm (of course there are other sizes!) I saw YOUR video about "bank line" and plan to get some. 👍

Bank line seems to come in many U.S. sizes, from 2mm-3mm being very common. 4mm bank cord is also available.

I want something lightweight to connect gear to, like a follower cord for a Tibloc, to pull it up the main climbing rope. So it's not necessary to be rated for a lot of kN or lbs. of force. But I'm don't wanna go TOO small with the bank line at risk cutting my climbing rope. I know your example is extreme. But if I choose bank line that's around 3mm, how much less likely is that to be able to slice through a 10-11mm climbing rope??? 🤔

how realistic would this be in a real scenario though?
