Petitjean Thread Splitter
The Petitjean Thread Splitter is a specialized fly tying tool designed for splitting tying thread, developed by renowned Danish fly tyer and designer Marc Petitjean. It allows fly tyers to easily and precisely separate twisted or multi-strand threads for creating dubbing loops and applying advanced material handling techniques.
The tool is especially useful for the split thread dubbing technique, where the thread is separated and dubbing material is inserted between the strands. This method allows the creation of strong, evenly distributed, and highly versatile fly bodies for nymphs, wet flies, and streamers.
The fine precision tip is designed to easily enter between thread fibers without damaging them. Its compact construction makes it convenient for use both on the main fly tying bench and in mobile tying kits.
