I followed the instructions from Geoffrey Budworth's 'The Complete Book of Decorative Knots', to tie this modified 4 lead 5 bight T handle turks head knot on the handle of a walking cane. I've seen a few examples done on a ship's wheel/spoke and on a hammer.
I also used a new lacing needle when tying this turks head knot. My friend Manny made me a couple of them from hollow knitting needles. They're larger, but not threaded like the Perma Lok needles. After cutting them down to size, Manny formed a lip at the open end of the needles, so that they do a good job of holding on to the paracord after it's inserted.
For tying the turks head knot, I used some orange paracord that I bought during a visit to the Grand Opening party of the new Going Gear store in Smyrna, Georgia. Among all the neat gadgets, gear, flashlights, and gizmos, they also carry some 550 paracord that has 8 inner strands compared to the usual 7 strand core 550 paracord. I think the extra strand gives the paracord a bit more of a solid feel to it. The inner strands of paracord can be useful for those that want to remove and use them for other tasks if the need arises.
There's a tutorial for tying a T-shape turks head knot on the KHWW.net website.
