Zach Thull is a career machinist, manufacturing executive, product developer, and co-founder of Dauntless Manufacturing. His background spans Department of Defense work, firearms and defense manufacturing, precision machining, CAD, facility management, OEM development, and the design and production of American-made knives and tools.
Professional Background
Thull entered machining while still a young adult, developing his trade through technical education and practical shop work. He later worked as a Department of Defense civilian, including assignments connected with the Explosive Ordnance Disposal Technology Division at Indian Head and Naval Air Station Patuxent River. That work placed him in demanding technical environments where manufacturing accuracy, repeatability, documentation, and reliable function were operational requirements rather than marketing claims.
After leaving government work, Thull spent approximately seven or eight years in the private firearms industry. His experience included firearms design, testing, production, engineering implementation, and the management of facilities supporting firearms and defense manufacturing. Dauntless Manufacturing’s official biography credits him with two patents related to defense designs.
Dauntless Manufacturing
Thull co-founded Dauntless Manufacturing with fellow career machinist Chris Moss in 2017. The company began in a garage in central North Carolina with a used CNC mill and a plan built around three potential lines of work: manufacturing consulting and reshoring support, research-and-development assistance for firearms and defense companies, and internally developed products.
The company’s first branded product grew from a collaboration with knife designer Matt Helm. Dauntless licensed Helm’s Persian design and initially planned a small production run. Strong demand led to continued production and helped redirect the business toward knives. Thull and Moss continued working full time in the firearms industry while building Dauntless, with Thull transitioning entirely to the company around 2020 or 2021.
Dauntless now manufactures its products in-house in central North Carolina. Its work includes fixed-blade knives for everyday carry, outdoor use, hunting, hard-use utility, and specialized applications, along with sheaths, accessories, collaborative designs, and OEM production.
Manufacturing and Business Responsibilities
Thull’s role combines technical manufacturing knowledge with responsibility for the business systems surrounding production. He leads business development and customer relations while also managing shipping, purchasing, and process development. His CAD work supports OEM projects and helps translate concepts from customers and collaborating designers into manufacturable products.
This position requires balancing design intent with material selection, machining limitations, production cost, heat treatment, finishing, sheath compatibility, quality control, and repeatability. Thull also contributes directly to knife design, applying an engineering and manufacturing perspective to geometry, ergonomics, durability, and intended use.
Product Development and Collaboration
Collaboration is a central part of the Dauntless product model. The company has produced designs with makers and subject-matter experts including Matt Helm, while Thull and Moss have also developed their own knives. Thull describes his personal design language as comparatively geometric and brutalist, emphasizing usable forms and clear functional intent.
The company’s catalog reflects both historical references and modern requirements. Some designs reinterpret established blade patterns using contemporary steels, manufacturing methods, handle materials, and carry systems; others are purpose-built around everyday utility, field use, hunting, or personal-defense considerations. Thull’s work involves deciding which features should be retained from a historical pattern and which should change to serve the modern user.
Areas of Expertise
Thull’s principal areas of expertise include precision machining, CNC manufacturing, design for manufacture, CAD, firearms and defense production, process development, facility management, OEM knife manufacturing, material and component selection, product testing, purchasing, business development, and customer relations.
His long-term backpacking experience also provides practical context for evaluating cutting tools used outdoors. Rather than viewing a knife only as a manufactured object, he can consider how dimensions, weight, edge geometry, handle design, sheath placement, corrosion resistance, and maintenance affect sustained field use.
Primary & Secondary Involvement
Thull appeared with Matt Landfair on P&S ModCast 425 — Dauntless Manufacturing, released April 10, 2025. The conversation examined Dauntless products, knife design, materials, production methods, the backgrounds of its founders, its early collaboration with Matt Helm, and the development of a small manufacturing venture into an established knife company.
The episode also addressed the relationship between design and application: selecting steels and handle materials, adapting historical blade forms, working with outside designers, building products in-house, and explaining why a particular knife exists beyond its appearance. Thull’s contribution to the Extended Primary & Secondary Network connects the user’s requirements with the less-visible engineering, manufacturing, and business decisions required to produce reliable tools.
Professional Significance
Thull’s career links government and firearms-industry manufacturing with small-business ownership and domestic knife production. He brings the perspective of someone who has worked both inside large technical organizations and in a company where design, machining, purchasing, fulfillment, marketing, and customer support remain closely connected. That breadth helps explain not just how a product is conceived, but how it is made repeatably and supported after it reaches the user.
