Ok guys, this is it. Bill, The exposed tang os a good Idea for 1/2 inch. It will have a lanyard hole for those who want to use the 2 finger chop grip. It should be slightly harder than dead soft, Bill, sort of like the spine of the blade I would say. The slabs will Wood or horn. If the Kami's feel that the horn may be too brittle for screws, then wood it is. Like I said earlier I have no experience with buffalo horn so cannot say. The Kami's should know from working with it so much. Bill maybe you can ask them which is better, and that's what we will go with. Either way is fine with me.
Tom, I don't want buttcaps, because it's another thing to worry about comming off or loose. A solid exposed tang is much stronger.
I hope this satisfies everyone, because this is the final. We will now leave it to the Kamis.
