Syb - My girlfriend (from whom I stole the thing) calls it a yarn needle, but it just looks like a big needle. Its a little smaller than the one I use to splice Amsteel, and a lot pointier. I had a lot of trouble at first too, and I think it was because I was tapering the end too much, so I've only been pulling two strands out and only about an inch up. A few times now I've done it without even tapering, and it worked pretty well.
