Basic Sheath Questions: Finishes, Sewing, Glueing

[Drac]

Hi guys,

I have read that the preferred thread for sheath making is 7 stands. I have found a shoe repair store that will order it for me @$30 a roll, about 4" in diameter. I was wondering if this was a good price? If so, how do I prep it? Should I just wax it like linen?

While buying some supplies I was taking to the storeowner and he was commenting on a couple of things. When I asked for an edge slicker he said that the slickers didn't come in a size big enough. He said to use a polished wood rod. Anyone have a better way? He also said that neatsfoot oil would cause a break down the fibers as the color it gives is from burning the fibers

Last question is how long should a good sheath last with being carried for hunting/camping? And what could I recommend for proper care to help extend the sheaths life?

Thanks for your time,
Jim
