San Diego, CA–May 22, 2025–It is a rare moment when a product, a designer, and a legacy blend into one perfect moment. Robert Young Pelton has been working and living in the bush, war zones, and dangerous places since he was ten. He designed his first knife in 2008, and 17 years and over two dozen patents later, he is still perfecting the Hostile Environment Survival Tool—a proven design that is beautiful, ergonomic, dependable, and functional. In that obsession lies an ancient concept of elegance, form, and function, designed to be used roughly and to age with grace. This is a perfection of that vision
The DPx Gear HEST/F 4.0 Ti is design integrity, manufacturing precision and finish sculpted from the world’s finest metals. Aerospace-grade 6Al4V titanium alloy and Magnacut martensitic stainless steel are formed by powder metallurgy, then precisely machined and hand-crafted in Northern Italy out of American materials.
There is another design ethos. Hard work must make the DPx HEST/F 4.0 Ti more beautiful as it begins to patina and adapt to your use and personality. Every scratch, nick, and polishing from everyday carry speaks to your taste in heirloom-quality products. Your watch, your car, your pen, and how you live becomes a collection of fine things and great moments—moments where the joy of using a perfectly designed tool makes you smile. That sense of satisfaction is exactly why RYP designs and makes products.
RYP confirms,
“The DPx Gear HEST/F 4.0 Ti has perfect balance. Lightweight enough to disappear in your pocket, yet robust enough to endure combat, survival, or daily use without failure.”
The direct byproduct of RYP’s lifetime of using and abusing his own designs in the harshest, most dangerous environments. From Ukraine to Chad and back.
The DPx Gear HEST/F features a host of patented features: custom-designed 7/64” hex screws, 440 stainless lock bar, our rapid opening notch, wire stripping jimping for fail-safe grip, tungsten carbide glass breaker, the hex drive socket, and deep reversible pocket carry And a lifetime warranty. All distilled from the hard-earned needs of users in unforgiving environments.

Learn about the legendary man, Billy Waugh and see the knife he inspired: The RYP and Bill Harsey Designed, Billy Waugh DEMO Folder.
RYP first met Billy when he was writing his book Licensed to Kill, Hired Guns in The War on Terror. Driving his cop Harley across the country during the winter, Billy graciously took out time from his wedding day to meet at the local Waffle House.
The two men - one an author, and one an operator, both veterans of numerous hot spots often at the same time - hit it off immediately. They have been fast friends ever since.
