Nifty edge protector I read about but forgot

I can't remember where I heard it, maybe it was in a forum post here.  Someone described putting a 22cm screw on a biner as a reserve for making a v-thread and they wrapped the screw in something that doubled as an edge protector.  That sounded like a neat idea and I'd like to try it but I forget where I read it and what the details are.  Any ideas?  It might have just been a piece of hose but I feel like it was a bit cleverer than that.

Since I'm sure I'll get someone asking "why?" and telling me me I shouldn't bother or something, this weekend I lead a party of three, after belaying the second I wanted to get photos of the 3rd so I fixed the free rope and lowered myself to get an angle, then jugged back up. When I got back up my rope had a pretty fucked up section to it.  I really should have used a protector.  I would like to add a small light protector to my kit when I'm leading a party of 3 like that.

Running the rope THROUGH the screw would certainly help.

I know Dave Searle posted about it here.

Looks like it's something called the Spiroll?

If that's what your thinking about?

Yes! That was exactly it! Thank you. His abalakov kit is nifty. Want to copy it.
