Keith,
I'm probably not the best to advise on this, as I'm a new maker, but I have done this before. Basically you need to trim the tang down to a stick tang making sure you include shoulders for a guard if your going to use one. Also, you want to make a shoulder on the spine about an 1/8 of an inch, this will allow the spine and the handle to be in line with each other, I know I'm not explaining this very well,like I can see it in mind head. If you want me to explain it better I can draw it up and send it to you, I still have not been able to figure out how to post pics on here, holler if you want more help, nice design BTW, and I love the grind. Matter of fact I just finished one very similar, not as much of an up swept blade tip, I hand forged it out 1080, finished her off with mosaic pins on Desert Iron wood, sadly the iron handles were salvaged from the very first knife I was making back in June, I wanted the Iron wood more than I wanted the pins to be placed correctly, this was a trade off, as I got to use a set of handles that cost me 25.00 that I messed up when I first started making knives back in the summer. I know I was being a cheap A$$, if it matters, I was making it for me. Let me know if you want me to draw it up for you, shouldn't take me too long to knock it out,
