Thanks for the comments everyone!
I'm making a kydex sheath w/ a Tek-Lock for it, I'll post pictures when I get it done.
Charlie:
I used different grinds because the convex grind at the tip is arguably stronger (than a hollow and a flat) for penetrating hard materials. Also, if you look at the cross-section of a bullet or the edge of an axe, it's convex for better penetration; flat grinds tend to wedge in the material and hollow grinds are not that strong. I ground the main part of the blade using a hollow grind for better slicing. I could have put a different grind on the swedge, but figured that if I used a flat grind, then I would have covered all the grinds.
In retrospect, if I were to make another one for myself, I would probably flat grind the swedge at a steeper angle and sharpen it too. However, since I have several customers from Europe and a double edged knife is illegal there -I decided on the unsharpened swedge.
