Spyderco Jumpmaster, Black FRN Handle, Serrated Fixed Blade Knife
A Major in the U.S. Armys 82nd Airborne Division contacted Spyderco sourcing a better knife for their Jumpmasters. More than a few of their crew already carry Spydercos and were familiar with our serrations and manufacturing quality standards.
When jumping out of a plane, airborne servicemen are attached to a static line, jumping one per second with a Jumpmaster insuring they get out and are clear of the plane and next jumper. If someone doesnt clear because of equipment failure or just poor luck, the Jumpmaster is ready with a reliable cutting tool. Once clear of the aircraft jumpers still need a reliable and quick-cutting blade in case they need to cut themselves free.
The Armys 82nd Airborne set out what they wanted in a knife and Spyderco complied by making the Spyderco Jumpmaster fixed blade. Their wish list included a rust-proof hollow-ground H-1 blade with a Sheepfoot (Rescue) profile. The blade comes fully serrated to quickly cut through ropes, lines, webbing or fabric. To keep the knife firmly in hand yet light and easily maneuverable, the handle is made of fiberglass reinforced nylon (FRN) that is Bi-Directionally Textured® for a secure grip. The tang of the blade is skeletonized reducing the weight even more.
The knife carries solidly in an injection molded polymer sheath thats curved, designed to carry against the body or calf without flaring or hard spots. Nylon straps on the sheath offer multiple attachment options and a lanyard hole in both the blade and handle are for additional back-up attachment.

Quick! List the most respected and innovative knife companies you can think of. If you know anything about knives, Spyderco is somewhere near the top. Spyderco Inc. makes some of the most unique and downright bizarre knife designs you'll see on the market, but from the number of passionate fans discussing, debating, and learning everything they can about Spyderco knives, it's clear that the company has done something right.
From the Glesser Family and the Spyderco Crew:
Since starting Spyderco we've been told our knives are different, peculiar, even out there. All true. Thinking beyond established knife industry barriers allowed us to introduce new and radical innovations to the knife culture including: One-hand opening, serrations on a folder and a clip to attach a knife to a pocket.
We didn't go into business to rake in a mountain of dough we're here for more selfish reasons- indulging our passion for creating knives. Spyderco is definitely out of the norm in the knife industry in our dedication to researching and developing fresh, improved and better performing materials all with function and reliability being key.
Someone once said to Sal Glesser, Spyderco's owner, "You must design in the dark because your knives look so strange." True again. Our recognizable appearance is a result of designing ergonomic functional tools rather than applying lipstick and nylons to a pocketknife. We may look curious, homely, whatever, but we'll never be called unusable or undependable.
Making knives that consistently deliver reliable high-performance requires an ongoing commitment to testing. In our million-dollar testing facility we examine edge retention with a CATRA machine, look for rust development with Q-FOG, check the force needed to open and close a knife. We also repeatedly test for stress, wear, optimal heat-treating and actively search for higher quality, performance enhancing steels and materials.
As a customer you probably don't think about this, or much care, but it allows us to put forth a promise. When you purchase a Spyderco you are buying a high-quality reliable cutting tool designed and manufactured for peak performance and ergonomic comfort. Those Who Know Carry Spyderco.
