About This Knife, extracted from the manufacturers website and furnished by the email provider to this site (not verified by me):
The MPK-Ti was designed to meet the requirements of the Navy SEAL's and has also been adopted and issued by the United States Marine Corps Recon personnel. A titanium, light weight, non magnetic, non corrosive, and multi functional knife that can be used in all environments from the tropics to the arctic.
The MPK is made from a high strength beta titanium alloy which has the disadvantage of being difficult to grind and machine, and higher in cost when compared to Ti-6Al-4V. Wear resistance, however, is superior and the alloy can be hardened to Rc 44-46 while maintaining usable ductility. At this level, edge retention is good. Furthermore, corrosion will not dull the edge.
THE HANDLE-
The MPK handle is injection molded in one piece, over a full length tang, and is textured and grooved for superior gripping. The handle is made from a high toughness Hytrel reinforced with the ballistic fiber Kevlar (Hytrel and Kevlar are registered trademarks of DU PONT). It is resistant to the effects of heat and most oils, fuels, and solvents. A metal guard and butt cap are not used. This ensures the handle is electrically insulated from the blade.
THE MPK - HOLDING AN EDGE-
The titanium alloy used for the MPK is heat treated to a range of Rc 45-47. At this hardness, resistance to abrasion is exceptional. This will be demonstrated when the edge is resharpened. Mission Knives has found that a diamond coated round sharpener works best for this purpose. The MPK will not corrode or dull under any conditions in sea water, making it ideal for a high use knife in that environment. Extended field tests have substantiated that the V-ground blade has a durable edge which is not susceptible to wear or chipping. The rounded serrations are superior for cutting a variety of materials.
THE SHEATH-
Hytrel is also the material of choice for the sheath. Kevlar is added to offer the best combination of toughness, hardness and low noise signature. The sheath is designed for a close fit to the blade, preventing movement of the knife and eliminating a potential noise source.
The sheath is designed to be worn on either side of the hip on a military utility web belt. Since the MPK will be used on various utility belts, it is also configured for ease of installation without having to disturb other items. Two pairs of tie-down slots were recently added to convert the sheath into a load bearing unit. Optional ballistic nylon carrying pouches can be strapped and secured onto the sheath by running Velcro straps through these tie-down slots.
