Bought as I was struggling to get the core back in to the cover while splicing a new tightly sheathed polyester braid on braid rope. Initially I tried without success to push the smallest Selma fid (4mm) with core attached back into the outer cover of 8mm rope but unfortunately the fid stuck real tight due to a lack of volume in outer, instead I used this d-splicer to pull the core through the outer, still tight but with a little patience totally possibly without much effort.Matt (Jun 29 2023, 22:26 pm)
