The Tanto-1 IS listed on the website, but for some reason there isn't a picture of it. Like any of the "1" specified one piece knives it's a 9'' blade. It's not one of the hot sellers and a small amount are made each year. I have one that was made in 2000 I believe (I'd have to check the card) and I seem to recall being told that only 25 or so were made that year. Not too hard to find though. It was my first one piece and I use it quite hard. With the thick tip it's pretty hard to do any damage to the things. I have some very minor chips in the edge but that's about it. Should be gone in a few sharpenings.
I don't believe a Tanto 2 will be coming along any time soon as it wouldn't be a very hot seller either. If you want a smaller tanto, CRK made a NICA one piece to go along with the NICA sebenza and I believe it was a 5 1/2'' blade (which would be the equivalent to a Tanto 2). It looks like a scaled down version of the Tanto 1. You could probably find one between posting a wanted ad here and keeping your eye on Ebay.
Hope that helped ya!
