Some of the needles are kind of strange looking, flat with a split on one end. The sinew is flat also so I think they are meant to be used together.

Uplander those needles you're speaking of are for lacing and IMO next to worthless :barf: even though that's all that was available for a good many years.
When you raise up the end you will see a couple of tiny prongs on one side. You put the lace into the needle and then press it flat until the prongs pierce the lacing and you're ready to lace your project. These needles were notorious about the lacing pulling straight out and away from the lace.

Tandy has had a newer needle out for years now that works 210% better although it's been so long that I have forgotten what they are called!:foot:
It is a piece of round brass with a small hole that has been threaded a short ways inside and a tapered blunt point on the other.
You cut your lacing to a thin sharp point and then simply screw the needle onto the lace and you're ready to go!!!!:thumbup:
You can pull quite of lot of lacing through the project without any of the troubles the old needles gave and almost always have to unscrew the last three inches or so of the lace out of the needle so you can install a new piece.

I don't know about now but they used too come in two sizes, a small and a large for the wider and heavier lacing.
I've had my two since the mid '70's and they still are like brand new!:thumbup:
I've misplaced them a time or two and had to dig around through all my crap to find them but you won't wear them out doing hobby work, I guarantee!:thumbup:
Also Andy is spot on when he says to use the dull needles. Most leatherworking needles are blunts anyway since the holes are already there to sew through. The best stitch to use is the double needle stitch, You use one piece of thread, pretty long, maybe six foot, and put a needle on each end. You start by pulling one needle through the first hole and drawing up the thread until it's even. Then go through the next hole with the left needle and do the same with the right needle and pull taught. Then simply do the same until the thread is used up, cut a new piece of thread and repeat.
What you get is a sewn seam with two threads running through each hole making the double needle stitch the strongest leather sewing stitch out there!
