No, it's a spliced joint rather than using ferrules. The sections are taped or wrapped together. It's fairly common on bamboo spey rods. Lighter, transfers energy better, and can't be torqued off.Two of the sections are cut/shaved through the rod from one side to the other. Is this just to show the composition of the inside of the rod?
Thanks Tim and redietz! Those had me scratching my head, never saw those before.Jojer, on the main page Carlin shows a cross section showing how the rod is made. On the Spey page he is showing a rod made with spliced Ferrules.
Spliced ferrules are sometimes used on Bamboo spey rods as some feel a spliced ferrule is better than a metal ferrule in that application.
Spliced ferrules are usually held together with a high quality vinyl or electrical tape like 3M makes.
