My heart palpitated at the title, 15's my everyday fave. Then noticed it wasn't official kabar or Ethan who originated the thread. Then depression set in. (Sorry, DunkEm, wasn't your fault, I just love that blade)
Not sure if I'm adding more than has already been suggested, so I'll divide it into "reality" sprint run and "fantasy" nano-sprint run for a pseudo production knife.
"Reality"
-a stainless or semi stainless blade steel Kabar has been known to make, sv35 or D2. Stonewash finish. Very nice.
-same handle but with a set of custom liners that could be stacked to fit. (Kind of like modular pistol blackstrap idea) a unique handle color that complements the Stonewash would be nice but not required.
-a sheath that can fit the custom liner stack, I figure the custom sheath folks can accommodate people who want more.
-stainless hardware
-optional: A custom steak block by TommytheWho to hold a quantity of these for Bladite. With his Avatar logo on it.
"Fantasy"
-same as above but upgraded handle material & gatorwrapped kydex by Julio.
-A touch of decorative engraving, Fisk style.
-Jerry Fisk'd convex light saber grind. So fine, like accidental cold fusion sharp fine.... Oh yeah....
-Personal delivery by Ethan & Jerry accompanied by the Swedish Bikini Team (SBT), that's as good as it gets; hold the Old Milwaukee...
-Optional: Full Beckerhead gathering at delivery to celebrate this at a ranch in Texas that runs helicopter hog hunting, full rock and roll (with SBT hosting)
Is that too much to hope for?
