The story of Curtiss Custom Knives is not one of overnight success or a single defining moment. It is the product of decades of mechanical experience, personal resilience, and a deeply held belief in building with purpose. At the center of this story is David Curtiss, a craftsman whose journey into knifemaking is as honest and straightforward as the tools he creates.

Raised in Columbia, Tennessee, Curtiss displayed mechanical aptitude from a young age. He was never particularly interested in classroom education, but he was always fascinated by how things worked. This natural inclination led him to enlist in the United States Navy at 18, where he would serve for twelve years. His naval career began in aviation maintenance and later transitioned to work as a Seabee construction mechanic. His service took him around the world and offered him invaluable experience in repair, fabrication, and operating in high-pressure environments.

After leaving the Navy, Curtiss returned home and explored a variety of jobs before opening a four-wheel-drive and off-road fabrication shop in Middle Tennessee. As a longtime Jeep enthusiast, he immersed himself in rock crawling competitions and the broader off-road community. These years deepened his fabrication expertise and introduced him to heavy-duty materials, real-world testing, and the kind of demanding tolerances that would later define his knife work.

After relocating to the Midwest, he accepted a position at an RV component manufacturer in Elkhart, Indiana. Though he initially intended to work in a hands-on role, he was placed in a management position and tasked with launching a second-shift production program. Over two years, he oversaw more than 120 employees and gained extensive experience with CNC machines, manufacturing workflows, and large-scale operations.

Ultimately, differences with company leadership led him to resign. He made a personal decision at that point to return to self-employment with a new focus. He purchased a water jet cutting machine and launched Great Lakes Waterjet from his garage. Working out of a three-car garage, he dedicated two-thirds of the space to the business. Without the benefit of modern social media platforms, he marketed his services through online forums, word of mouth, and small-scale outreach.

Roughly a year and a half into the venture, a job came in requesting knife blanks cut from 1095 carbon steel. At the time, Curtiss was unfamiliar with blade steels and knife design in general, but he took the job, sourced the material through Admiral Steel in Chicago, and completed the work. One of the blanks had a miscut and was left over. Curious, he posted a photo of it on a knife forum to see if there might be other makers interested in outsourcing their knife blank cutting.

The online post quickly caught the attention of the knife-making community. Among those who noticed was custom knife maker Dan Gray, the original designer of the blade profile. Recognizing his work, Gray confronted Curtiss, unaware that the parts had been subcontracted. Though it began as a misunderstanding, it evolved into a candid and constructive conversation. Curtiss walked away with a crash course in knife community etiquette and a deeper understanding of intellectual property and design ethics. That pivotal exchange marked his transformation from outsider to respected contributor in the knife-making world.

Following that experience, his business rapidly expanded. He became a trusted supplier of water jet-cut components for knifemakers around the globe. At the peak of that work, Curtiss was producing parts for more than 500 individual makers, ranging from hobbyists to full-time professionals. While the work was fulfilling, the desire to create something of his own grew steadily stronger.

Eventually, he began designing knives himself. He chose a challenging entry point, a frame lock flipper with a bearing pivot. From the start, his approach emphasized mechanical precision, strong lock geometry, and ergonomic integrity. He made mistakes, scrapped parts, and restarted builds until the process and product met his standards. When he completed his first knife, he posted a photo online, and within hours, it had sold to a collector in California for $500.

Among Curtiss’s most recognized designs is the F3, introduced in 2011. Built around the same principles that guided his earliest experiments, durability, utility, and precision, the F3 quickly became a cornerstone of his lineup. Its construction reflects Curtiss’s commitment to building hard-use tools that remain reliable over time. With only minor refinements throughout the years, the F3 continues to be loved by users who value dependable performance and purposeful design.

In 2021, Curtiss moved his operation from the garage into a dedicated 3,600 square foot facility just across the Michigan state line. Outfitted with industrial-scale CNC equipment, including a Haas milling machine, his new shop gave him the space and tooling to further refine his builds. While the added capacity initially led him to explore the idea of scaling up to small-batch production, he ultimately returned to his roots in one-off custom manufacturing. The shift reaffirmed his belief in quality over volume.

All components of a Curtiss knife, excluding pivot hardware and screws, are made entirely in-house. Even heat treatment is performed on-site. Maintaining complete control over the process ensures that every knife meets Curtiss’s high standards. He inspects and finishes each piece himself. Over the years, he has considered bringing pivot and screw production in-house, but the capital investment and logistics have made it a long-term consideration rather than an immediate objective.

Curtiss has rarely had employees. Aside from a local apprentice who helped during summers and school breaks, his only long-term collaborator was Matt Christensen. Christensen, now the founder of Christensen Knife Works, worked with Curtiss for over a year, commuting daily from Illinois. Curtiss saw Christensen’s potential early on and encouraged him to pursue his own business. Today, the two remain friends and respected peers in the industry.

His current shop remains primarily a solo operation. The workflow is efficient but deliberately paced. Curtiss emphasizes that building a high-quality knife requires time, attention, and care, none of which can be rushed in the name of productivity.

Although Curtiss has concentrated much of his work on folding knives, his portfolio also includes slip joints and a limited selection of fixed blades. Among these, slip joints hold a special appeal. Their mechanical intricacy and timeless design continue to offer a rewarding challenge, drawing interest from both seasoned makers and dedicated collectors. While the broader market has leaned increasingly toward tactical and everyday carry folders, Curtiss remains deeply connected to the craftsmanship and heritage found in traditional patterns. If freed from the demands of commercial production, he envisions spending more time creating slip joints purely for the satisfaction of the process.

In addition to custom work, Curtiss has participated in limited production collaborations. Most notably, his Nano design was licensed to Boker for a production run, allowing a wider audience to experience the design at a more accessible price point. While he has kept most of his work in-house, he remains open to future partnerships that align with his standards for quality and consistency.

Curtiss has exhibited at numerous knife shows over the years, including Blade Show in Atlanta. While the scale of these events has grown dramatically, with thousands of tables and attendees from around the world, he finds that smaller shows often offer more meaningful interaction. One of his favorite events is the Spirit of the Blade show in Troy, Ohio. He participated in the inaugural event and helped promote it through his own channels. Collectors traveled from as far as Florida and Wisconsin to attend, and the atmosphere allowed for real, one-on-one conversations with customers.

Other shows he has supported include the East Coast Custom Knife Show in Fort Lauderdale, the Badger Knife Show in Janesville, Wisconsin, and local events in Nashville, Tennessee. Curtiss prefers shows where makers and collectors can connect without being overwhelmed by crowds. In his view, smaller gatherings still reflect the community-driven spirit that first drew him to knifemaking.

Throughout his career, Curtiss has taken pride in mentoring others. Whether offering CAD help, cutting parts for new makers, or simply answering questions, he has always believed in giving back to the community that helped shape his own career. He credits much of his success to those who offered support when he was starting out and sees it as a responsibility to continue that cycle.

Now approaching his 59th birthday, Curtiss has no plans to retire. His work remains a daily pursuit, not out of obligation, but out of passion. He continues to design, build, and refine his knives one at a time, ensuring that each one that leaves his bench is the result of personal attention and decades of experience.

Curtiss Custom Knives is more than a brand. It is the embodiment of a craftsman’s philosophy. Built with intent, tested through use, and refined by the maker’s own hands, each knife reflects the journey that brought it into being. For David Curtiss, the work is far from finished. As long as the shop lights are on and the tools are within reach, the next knife is already taking shape.
