Design help

[balisongman07]

Ive been on this forum for a couple of years now but besides one post on the multi tool subforum, im ALWAYS on the balisong sub... but ever since i saw a Dao Flipper from Micheal Burch (Burchtree bladeworks) i've wanted a flipper, ive had one before (a CRKT M1610KZ i think was the model number, got it at walmart.) but i want a custom one made.. first im askin for help on finishing the tang of the design, i want it to have IKBS, and be a Frame lock. Heres what i have so far on the design. (ignore the already drawn tang, it was just to get a feel for it)
