Jake -- I have three quick solutions off the top of my head:
1) $180 solution - buy a Chris Reeve Professional Soldier. Already pointy, but expensive. S30V, not quite as tough? A little thicker though, and full thickness close to the tip. Nice stonewashed finish, saves us the trouble of removing coating if desired. Shackle wrench interior leaves lots of room for nice paracord wrap.
2) $60 solution - buy a Buck/Mayo neck knife. Pointier than Bk11, but S30V, so not as tough. Not as easy to wrap? Cheaper sheath.
3) $36 solution - buy another BK11, grind it to resemble BK9 tip. Basically, clip with swedge. Hmmm, might have to try that. Or grind just the clip.
Dang you, now you've got me thinking about it, and being the spendthrift that I am, I'll probably eventually end up with all three solutions. Arghh!
Seriously though, thanks for getting us thinking about it. Maybe Ethan's already working on the BK11/BK7 neck knife version, with a 4" handle and 4" blade. Hmmmmm...
