Yes, the thick nylon thread I was referring to is not the clear angling sort. It is made up of many smaller strands twisted together to get a thicker thread. It can be compressed.  
 
I guess the point is that regardless of material used to wrap the peksi, the wrapping must provide some tolerance -- i.e. a snug fit, but the hilt can be twisted without too much effort.
