C&F Design 3-in-1 Nail Knot Pipe
Essential tool to tie fly line and tapered leader. Splice the tapered leader to the fly line, then use pipe included to create nail knot with small bundle to avoid entangled with top guide. When drawing a line from the top guide or hauling in a fish, it becomes much comfortable just by eliminating the interference with the guide by minimizing the bundle. Small magnet on the tip of nail knot pipe is convenient for picking up small flies from compartment box. It also can be used to temporarily hold flies when switching flies.

This nail knot pipe makes fly tying much smoother. The magnet helps me grab small flies quickly, and the knot stays secure without tangling with the guide. I use it every time I switch flies on the water.

Works well for creating a compact knot. The small magnet is handy when I’m changing flies mid-day. A little more durable would be nice, but overall it’s reliable.

I’ve used this with different fly lines and it consistently prevents tangles. The design is simple but effective. Great for anglers who value smooth line handling.
