John Brockway, toolmaker and videographer (Linda Hendrickson's husband) shows how he makes gripfids from hollow knitting needles.

The gripfid is the invention of the late British knotting expert, Stuart Grainger. John first shows a gripfid that Stuart fabricated from brass tubing. This method is explained in Stuart's book, "Knotted Fabrics".

John then shows a variation of the gripfid made by William French. This led John to try making gripfids from hollow knitting needles. The advantage of this method is that the point -- the most difficult part -- is already made.

John then goes step-by-step through the process of making the gripfid, which includes cutting, grinding, filing, and sanding.

The gripfid is an ideal tool for ply-splitting, a technique that fiber artists are beginning to explore as a way to make jewelry, baskets, rugs, and other two- and three-dimensional objects. Ply-splitting starts with plied cords. All ply-split objects are created by pulling cords *through* other cords (not just over and under as with other interlacement techniques). The gripfid is used to split the plies of one or more cords. Then the end of another cord is placed in the channel, and as the gripfid is pulled back through the split cords, it grips the splitting cord and pulls it through.

John makes tools for ply-splitting and tablet weaving. For more information about his tools and these two fiber art techniques, visit Linda Hendrickson's website.
