The Splicing Wand is the invention from master splicer, Brion Toss. It is basically a long tube containing a hidden snare. You slide the tool into the rope, snare the end you want to tuck, and slide the tool out. There's a specially-shaped tip on the tube, to keep you from snagging yarns along the way, an ingenious mechanism in the handle, to hold the tube in place while you work. You can clamp the tool in a vise if you want, leaving both hands free to deal with the rope, there's no taping or un-taping, no fid lengths to decipher,and very little physical effort needed to tuck.
For professionals it's the tool of choice, and is one of our own go-to tools for splicing here at Treegear.
For ropes between 5/16"-1/2" (8mm-13mm)
