Today’s tactical fixed blade knives still resemble the first Bronze Age
daggers of 4000 years ago, especially in their handle design. Michael
Martinez, sculptor, inventor, and martial artist, didn’t start out to
redesign the fixed blade, but he explains, "In my edged weapons
training, I kept noticing how many knives didn’t feel right, didn’t have
a grip that gave both control and comfort in the four fundamental
tactical grips." Michael’s design firm, Group Design, Inc., reached out
to a team of medical specialists for the answer. Their Ultima™ achieves
22 out of 23 ideal contact points with its unique patent-pending handle.
The injection-molded black Zytel® scales feature over 70 triangular grip
segments, separated by sipes, or “ooze grooves" which channel away
water, mud and oil. Horizontal grooves are placed under the fingertips
for optimum feel.
Because tactical knives are inevitably used as pry bars, Michael’s team
created a butt pry tip as an extension of the blade tang, with a rounded
The Ultima is available with a 6.75" or 4.95" full-tang blade of 1.4116
stainless steel with a light bead-blast finish. It is available with
Razor-Sharp or Combination Razor-Sharp and Veff™ Serrated edges. The
2125KV features a black titanium nitride blade coating.
Serrated models feature our exclusive patented* Veff™ Serrated edges.
Developed by Oregon City, Oregon, knife designer Tom Veff, these
serrations are wide and angled at 60 degrees to the edge. The resulting
cutting points bite instantly and dig deep upon contact, slicing
smoothly and effortlessly. They give dramatically improved cutting
ability on rope, webbing, strapping, hoses and leather.
An injection-molded black polypropylene Ultima Trainer is also
Tactical Sheath. The Ultima’s custom black Cordura®/Zytel® sheath has an
injection-molded liner. Dual belt loops are Velcro® adjustable. For
maximum versatility, there are ample grommets with a length of 550
paracord included, an adjustable leg strap, plus a slotted sheath back
that can mount on MOLLE gear. Removable security handle straps with
snaps give access and security. A utility pocket with a Fastex™ buckle
will carry a variety of folding knives, multipurpose tools or
After 4,000 years of scientific progress, the only thing the Ultima
shares with its bronze ancestors is its role in the mission.
