Doc Canada started my search into rope twisting when I was recuperating at hone for 6 months! As I was wheelchair bound I could not harvest any supplies, so in true survivalist fashion I used what I could reach- the hair left on my brush. It grossed out many people here, but did teach a coup rid things outside the skill- skills Canberra practiced anywhere (I still twist together Starbucks straw wrappers to keep practice. No matter where you are or the limitations within you should be able to manipulate the environment around you; I knew long ago survival skills hit people in their sensitive/cultured side- even among other survivalists! And best of all I have many many yards of VERY strong twine that I carry around with me, and it's nicely arranged lengthwise already! Further to this, I have used my hair in the field for quick lashing/tying off of small things, or to prove that the twine I can make is tougher and smaller than many purchased twine.
With hair I double twist by hand each twist as the hair is too fine, however I have used the leg roll technique on other materials that are a bit more fibrous. This fall I will probably see how hollyhocks work out- I forgot to last year until it was too late.
I really like the looks of the knife- congrats to the winner.
