I just started carrying my Jumpmaster 2 for self defense in the evenings when I go out for walks. The town I am in use to have astronomically low numbers for crime, but lately there have been robberies and holdups. I do not want to be out late at night and be taken by surprise.
The H1 steel and razor sharp serrated edges are never going to rust or pit, due to extreme weather or sweat. Sal claims that these serrations are in the high 60's HRC, which makes them quite hard and they should cut through anything worn, Summer or Winter.
I have many knives, but the sheath on the Jumpmaster 2 works great for a quick draw. I have so many knives that require effort beyond the norm to draw. What were these designers thinking?
I was splitting time between several other knives in my collection, I love the CTS-XHP and G-10 on my Les George Galvos Daggers, and the sheath works great, but it feels like a one trick pony....small dagger. If it were the exact same design and 5.5 inches long, well, OK then, sign me up, but it comes in with just a 4 inch blade. The Jumpmaster 2 seems hand-filling, and much larger, but it has just a .5 inch longer blade. I also carried the Winkler Knives II dagger in 80CrV2...nice knife, but there is no hilt and my hand could slide down on the blade if I hit a rib or something hard in a skirmish.

"The original Jumpmaster was designed at Ft Bragg by the Jumpmasters I worked with there. It was developed for Military applications." - Sal
The original Jumpmaster knife was developed in close cooperation with the U.S. Army 82nd Airborne Division's Jumpmasters as an emergency cutting tool to free "hung" paratroopers during airborne operations. A distinguished member of Spyderco's Salt Series of knives, its 100% rustproof H1 steel blade and fully serrated SpyderEdge not only made short work of military static lines, they also offered the most impressive edge retention of any knife we’ve ever made.
The Jumpmaster 2 proudly continues that tradition, taking the extreme cutting power of a fully serrated H1 blade and packing it into an all-purpose leaf-shaped profile that offers greater point utility and eagerly tackles all cutting tasks. Like the original, the Jumpmaster 2's nitrogen-based H1 blade is hollow ground and features a full-thickness spine and a skeletonized full tang for an outstanding combination of balance, strength, and light weight. Its injection-molded, fiberglass-reinforced-nylon (FRN) scales include Bi-Directional Texturing that, together with the handle's refined, ergonomic shape, ensure a positive grip in even the most demanding circumstances. To complement its versatile, do-everything spirit, the Jumpmaster 2 comes complete with a snap-fit, custom-molded Boltaron sheath and a versatile G-Clip mount that supports a full range of carry positions.
