First of all, thank you for serving.
Secondly, it's good to hear the rest of you made it out intact. Steel and undershorts can be replaced... I hope you gave 'em hell.
Call Eddie Killian and tell him your story. Ask for whatever K5 hawk is lying around and shippable. Any one of his axes will work well for you. If you aren't at an APO address though, expect to not get far. Several people have used similar stories to try to rip off good people here. Just want to give you a heads up about that situation so you're aware of it when you talk to the makers. A lot of makers/manufacturers are very sensitive to that kind of story. Also note that the K5 sheathmechanic sheaths are jumpable.
SOAB, I can't find Eddie's #, someone please post it here.
Alternatively call Justin Gingrich at 706-315-9127 (Justin@rangerknives.com)and he can make you a custom from scratch. He'll be at Blade this week, so keep trying next week if he doesn't pick up this weekend. Or check out the RD series and RD Hawk here

Check out the Crash Axe on the Swamp Rat forum. Give Eric/Garth/Jerry a call at (419) 923-6471 and tell them your story. Again, if you are at an APO address they will try to hook you up.
A call to the Strider guys may net you both axe and knife in short order. (760) 471-8275
For a replacement knife, look at another Strider, or Simonich knives, or the Chris Reeves Neil Roberts or Green Beret knives. Alternatively, you can get a Busse Satin Jack Tac or Hell Razor and pick up an appropriate sized Spec-Ops sheath for it at any PX in Iraq or Afghanistan.
