Thanks guys. I have fun with them still and there are so many things to do yet.
The design itself is an interesting progresion in its development. The handle started out with a flat top, flat bottom oval sides. Then they went to round top, flat bottom, then round top round bottom,. Somewhere along the line I played with the length of the bottom back portion what fits against the palm of the hand, so you will find some that are shorter and slightly more rounded on the end of the handle, then there are some that are a little pointer, then you will find those that have less or more sweep to that portion of the handle. All of it from field useage which is why it slowly developed. You will find just a few drop point ones, I think there are three full tang interals out there, 2 full tangs with guards not intergal, a couple with no guard but bolsters. Frame handles such as shown in this thread, a few have no rear bolsters, some with. All rear bolsters ones are engraved, there are no plain ones of that. There are just a few of them out there with no "thumb notches" thats cause I got distracted and forgot to do it before heat treating. For the most part they are concealed tang with the tang on all of them running at least 3/8 inch from the back of the handle.
Thats just information some of you might want.
