Thanks for the great feedback. A manufacturer can test a knife to death, but nothing compares to real-life testing in the field.
Handle Comments: I guess part of what you are looking for are at this post... http://www.bladeforums.com/ubb/Forum3/HTML/000518.html
But, more specifically, durability vs G10. The EOD team based out of the now closed ElToro Marine Base used an MPK to pound 5 boxes of 8D penny nails into a 2x4 using the butt of the handle. I admit, there were 2 small scratches on the handle butt when they were done. For those interested, Homer Brett has the knife.
We first started experimenting with Hytrel based on extensive meetings with DuPont. We were originally thinking glass filled ST801, but DuPont said that Hytrel would make a better fit. We also performed extensive testing on Kevlar loading including length of the Kevlar thread. DuPont helped considerably by supplying 6 x 50 pound bags of different Durometer Hytrel along with different lengths of Kevlar thread. It was left up to us to compound the mixture to the exact percentages we wanted. Graphs were completed showing strengths of the handle material (along the Y-axis) and ever increasing % of Kevlar (along the X-axis). When we achieved the "top-of-the-curve" we knew we had a material that was going to be hard to beat. During this testing, we heard that the Navy was starting to have trouble with some of the MD knives - on a couple of their knives, the handles fell off. This further convinced us that Insert Injection Molding was the ONLY way to go. I believe that the material and compound we have chosen is every bit as durable as G10, plus, it feels "warm" in the hand. You will have to pick up an MPK to understand what I mean by that - Maybe Nam, Will, Cobalt, Bob, or Cliff can explain better, it just feels warm and feels like an extention of your arm.......
We meet/exceed all of the US Navy requirements for the knife evaluations where they soaked the knife/handle in seawater, kerosene, gasoline, and other fuels, oils, and solvents, and seawater, and both knife and handle performed perfectly. They even held the blue tip of a flame from a propane bottle to the handle for something like 20 seconds. When done, we just brushed the black carbon away and the handle looked like new again. I believe that Tom Clinton has that knife. We have also tested the handle against DEET, the handle was not affected.
Anyway, I hope this helps.
