Mark Knapp 1911 Combat Survivor Knife

The Mark Knapp 1911 Combat Survivor Knife is a custom-built bowie design based on a slimmed-down 1911 grip frame.


As found on

Hi All, I wanted to show you a project I’ve been working on for a couple of years now. I wanted to do something really cool to celebrate the hundred year anniversary of the Colt 1911 pistol. I decided to build a survival/ combat Bowie on a slimmed down 1911 grip frame and use the magazine for a compartment to house some survival gear.

The first 10 are being donated to the NRA for fund raising auctions. The one pictured here is going to the National Banquet in Pittsburgh the other nine will be at banquets around Alaska.

The blade is 154 CM, 8 inches long, 1 1/2 inches wide and 3/16 inches thick. The overall length is 13 inches.

This one has premium blue mammoth ivory, and some extra special survival stuff in the mag.

I had some partners on this project. Caspian arms made the grip frames available to me at a reasonable price, Ken Jantz at Jantz Knife Supply made the blades for me to my specifications and donated ten for the NRA knives, and my friend Scott Hamann at Metal Magic in Kenai Alaska. was also very instrumental in the building of these knives. The magazine from the knife is functional in a .45 (gives you one more round if you need it) and the knife accepts a fully loaded mag for your .45 if you want to do that. Read more about this custom knife by clicking here.

Inside the magazine in the handle is:
The door of the compartment is a diamond hone
a Leatherman Micro
a magnesium and flint fire starter
a needle for sewing
a length of synthetic sinew for snares, fishing, sewing, a bow string etc.
fish hooks
it has capacity for a .45 round and a flashlight is on the lanyard.

  • ok, quick question, i see alot about this knife, so what is the price for what finish, what sheath does it come with (hopefully a kydex sheath and NOT nylon) can i get some kind of idea what this will run?

    I know Mark and how much he has put into this project. All 1911 owners should support this endeavor of a truly unique and functional knife.

    lone wolf already make a knife based on the 1911 grip, this is above and beyond what they’ve created though, love the idea of a magazine compartment. Now you just need to mass produce them!

    SWEEEEET!!!!!!!!!!!! Sad that noone has thought of this b4! Excellent commorative for the 100th of the 1911! A suggestion would be to do custom tactical versions with say Bill Wilson, Les Baer, Nighthawk Tactical, & Kimber. Just an idea. can definately see one of theses bad boys with custom Cocobol, G-10, or Micarta handles, especially with the Wilson or nighthawk logo’s! Two questions; Is the blade & handle forged from a solid piece & how much?

    And I thought the “crowbar with a sniper scope” was a silly idea; here we have the magazine-fed combat knife!
    This is an interesting innovation, and as a lover of the 1911, I couldn’t be more impressed with the design behind this knife.
