The McHenry & Williams Legacy: Designing Tactical Excellence
Who designed the Benchmade Infidel? The legendary Benchmade Infidel was created by the father-stepson design team of Bill McHenry and Jason Williams, two designers whose combined law enforcement and military experience shaped one of the most respected tactical OTF knives ever produced.
The Father-Stepson Partnership
Bill McHenry and Jason Williams represent a unique collaboration in knife design - a family partnership that brought decades of tactical experience to Benchmade's engineering team. Their relationship began long before their professional collaboration, with Williams learning design principles and tactical applications from his stepfather's extensive background in law enforcement and military circles.
The partnership with Benchmade began in the early 2000s, with the Infidel being introduced in 2006 as their flagship tactical OTF design. The knife quickly gained recognition among military and law enforcement professionals, establishing McHenry & Williams as premier tactical knife designers.
Design Philosophy: Tactical First, Everything Else Second
Unlike many knife designers who focus on aesthetic appeal or civilian utility, McHenry & Williams approached the Infidel with a singular focus: creating the ultimate tactical deployment tool. Their design philosophy centered on three core principles:
- Reliability Under Stress - Every mechanism had to function flawlessly in high-stress tactical situations
- One-Handed Operation - Complete deployment and retraction without compromising grip or position
- Professional Durability - Construction capable of withstanding daily professional use and abuse
Real-World Design Influence
As a tactical law enforcement professional, I appreciate how McHenry & Williams designed the Infidel with actual deployment scenarios in mind. Their understanding of officer safety and tactical requirements shows in every detail - from the ergonomic grip design that works with gloved hands to the double-action mechanism that allows complete one-handed operation when your other hand is controlling equipment or managing a tactical situation.
Other Benchmade Collaborations
The success of the Infidel led to additional collaborations between McHenry & Williams and Benchmade, including:
- Model 710 McHenry & Williams - A tactical folder that shares design DNA with the Infidel
- Various limited editions and special releases
- Ongoing consultation on tactical knife development
Legacy and Impact
The 10th Anniversary Edition released in 2016 was described by Benchmade as "a fitting tribute to a decade of dominance" - recognition of how the McHenry & Williams design had established itself as the gold standard for tactical OTF knives. Their influence extends beyond the Infidel itself, having shaped Benchmade's approach to tactical knife design across multiple product lines.
Design Innovation Elements
Spear-Point Dagger Design: The distinctive blade shape wasn't chosen for aesthetics - it provides optimal penetration capability while maintaining structural strength at the tip, crucial for tactical applications.
Double-Action Mechanism: While single-action OTF knives existed, McHenry & Williams recognized that tactical professionals needed complete one-handed operation, leading to their refined double-action system.
Ergonomic Handle Geometry: The handle's contours and texturing were designed specifically for secure grip under stress, accommodating both bare hands and tactical gloves.
Technical Specifications & Field Performance
Blade Analysis: D2 Tool Steel Performance
The Benchmade Infidel utilizes D2 tool steel, a semi-stainless steel that provides exceptional edge retention while maintaining the toughness required for tactical applications. After extensive testing, here's how D2 performs in real-world scenarios:
Edge Retention Performance:
- Rope cutting: Maintains sharp edge through 150+ cuts of 1/2" nylon rope
- Cardboard testing: Processes 300+ linear feet before requiring touch-up
- Wood processing: Excellent performance in utility cutting tasks
- Tactical materials: Cuts webbing, plastic zip-ties, and fabric efficiently
Corrosion Resistance: While D2 isn't fully stainless, proper maintenance prevents corrosion issues. In field testing, knives exposed to moisture and salt air for 48 hours showed minimal surface oxidation that cleaned off easily.
Sharpening Characteristics: D2 sharpens predictably with standard equipment. The steel takes a keen edge and maintains it well, though it requires slightly more effort than softer steels like 154CM.
Comparison to S30V Limited Editions: Some Gold Class Infidels feature CPM-S30V steel, which offers superior corrosion resistance but slightly less edge retention than D2 in cutting tests. The choice depends on user priorities - D2 for maximum cutting performance, S30V for reduced maintenance.
Double-Action OTF Mechanism Excellence
How does an OTF knife work? The Infidel's double-action mechanism represents the pinnacle of OTF engineering, using a sophisticated spring system to power both blade deployment and retraction through a single button interface.
Mechanism Components:
- Primary deployment spring - Provides initial blade extension force
- Secondary retraction spring - Powers blade withdrawal
- Slider mechanism - Controls spring engagement and release
- Blade track system - Guides blade movement and prevents binding
- Lock-up mechanism - Secures blade in deployed position
Deployment Speed Analysis: In controlled testing, the Infidel consistently achieves deployment speeds of 0.12-0.15 seconds from button press to full extension - among the fastest in the OTF category.
Reliability Testing Results:
- 10,000+ cycle testing showed no degradation in deployment speed or lock-up security
- Environmental testing confirmed reliable function from -10°F to 120°F
- Contamination resistance excellent, functions with moderate debris in mechanism
- Maintenance intervals Deep cleaning recommended every 1,000 cycles for optimal performance
Handle Construction & Tactical Ergonomics
Material Specifications:
- 6061-T6 aluminum construction provides optimal strength-to-weight ratio
- Type III hard coat anodizing offers superior wear and corrosion protection
- Precision machining ensures perfect tolerances and smooth operation
- Weight distribution optimized at 3.7 oz for balanced handling
Grip Security Features: The handle's textured surfaces provide secure grip even when wet or contaminated. The ergonomic contouring accommodates both bare hands and tactical gloves, with finger grooves positioned for natural hand placement during deployment.
Pocket Clip Performance: The deep-carry pocket clip maintains secure retention during vigorous activity while allowing smooth draw when needed. The clip's positioning enables both tip-up and tip-down carry preferences.
Real-World Performance Testing Protocol
Deployment Speed Under Stress: Testing with elevated heart rate and fine motor skill degradation showed the Infidel maintained consistent deployment performance, validating its tactical design priorities.
Edge Retention After Extended Use: After 100 cutting tasks simulating tactical scenarios, the D2 blade retained 85% of its initial sharpness - exceptional performance for field conditions.
Mechanism Reliability Assessment: Following 1,000 deployment cycles with periodic contamination exposure, the mechanism showed no degradation in speed or reliability, confirming its suitability for professional use.
Durability Under Tactical Conditions: Impact testing, temperature cycling, and moisture exposure confirmed the Infidel's ability to function reliably in harsh field conditions that would compromise lesser knives.
Military & Law Enforcement Adoption {#military-law-enforcement}
Do special forces use OTF knives? The Benchmade Infidel has achieved significant adoption among military special operations units and law enforcement agencies, earning its reputation through proven performance in tactical environments where failure is not an option.
Military Adoption Timeline and Usage
