Hansen Knot around the center section of my AA Tactical Maratac LED flashlight. The pictured knot is the fourth time I'd tied it around the light, the first couple of times being done with different types and sizes of cord, before using this 2.4mm braided nylon line.
I stopped tying to take a few photos, after my hands started cramping up a little, as they often do.
As I worked the slack out, the knot seems a bit lumpy in spots and I'm guessing that's because I tied it in the narrow section of the light, not having much room to keep the starting 5 lead 4 bight knot loose and spaced out enough before working in the Hansen pattern, where it started getting tight with the lacing needle before I finished.
I'll probably take this one off too and try again until I get it right, maybe just using paracord to practice tying the knot a few more times.
