The Knotters Tool is made for the paracord and knot tying aficionado. It's a simple instrument machined from a billet of aircraft aluminum, anodized black. Patches of knurling keep it grippy and a stainless steel steel clip allows you to keep it handy. The body has a hollow core that's roughly 3.5" long and 0.32" in diameter.
This model of the Knotter's Tool has three (3) different stainless steel stitching needles in the hollow core of the body. Each measures 3.5" length with diameters of 0.11", 0.15", & 0.18" to fit your needs.
