Hey all, we here at True Shot Academy are examining folding knives today. These versatile cutting tools have evolved from simple utility items into sophisticated everyday carry options combining convenience, functionality, and sometimes remarkable engineering. Unlike fixed blade knives, folding knives incorporate pivoting mechanisms that allow the blade to store safely in the handle, creating a compact package that fits comfortably in pockets or on belts. From basic slip joints to advanced bearing pivots, these portable cutting tools serve countless roles in everyday life. Let’s explore the defining characteristics, locking mechanisms, blade profiles, materials, manufacturers, notable models, and practical applications that make folding knives essential tools for many users.
Defining Characteristics and Locking Mechanisms
Folding knives differ from fixed blades through their incorporated pivot systems allowing the blade to rotate into the handle for safe storage. This pivot represents both the defining characteristic and potential weak point of folding designs. Modern engineering has created numerous locking mechanisms to secure the blade in its open position, each with distinct advantages:
Liner Lock: A tensioned metal liner inside the handle frame springs inward when the blade opens, preventing the blade from closing until the liner is manually pushed aside. This widely-used mechanism offers good strength-to-weight characteristics with relatively simple construction. Knives from CRKT, Spyderco, and numerous other manufacturers employ this common locking system.
Frame Lock: Similar to the liner lock but integrating the locking bar as part of the handle frame itself, typically providing greater strength. Chris Reeve popularized this design with his Sebenza, while brands like Zero Tolerance extensively employ frame locks in their premium tactical offerings.
Axis Lock: Benchmade’s proprietary mechanism uses a spring-tensioned bar that moves horizontally to engage a ramp on the blade tang. This ambidextrous design offers excellent strength and one-handed operation. The Mini Griptilian and Bugout represent flagship models featuring this mechanism.
Compression Lock: Spyderco’s proprietary lock functions similarly to a liner lock but positions the locking component on the spine rather than beside the blade. This creates additional strength by changing the force distribution while allowing safe one-handed closing. Their Para Military 2 showcases this innovative design.
Button Lock: Employs a spring-loaded button that engages a notch in the blade tang. This mechanism allows completely one-handed operation and appears in knives from Protech, Hogue, and several other manufacturers. Protech’s Malibu has popularized this mechanism in manual folding knives.
Back Lock: One of the oldest mechanisms, featuring a rocker bar along the spine that drops into a notch on the blade tang. Buck Knives’ 110 Folding Hunter made this classic design famous, with modern versions appearing across numerous manufacturers’ lineups.
Slip Joint: Not technically a lock but a tensioned bar that holds the blade open through spring pressure. This non-locking design appears in traditional pocket knives and modern “modern traditional” designs. Case Knives specializes in these traditional patterns.
Opening mechanisms vary from traditional nail nicks requiring two-handed operation to thumb studs, blade holes, and flipper tabs designed for convenient one-handed deployment. High-end models often incorporate bearings or washers at the pivot to reduce friction and improve deployment smoothness.
Common Blade Profiles
Folding knives incorporate the same variety of blade profiles found in fixed blades, each optimized for specific cutting tasks:
Drop Point: Features a convex curve from the spine to the tip, creating a strong point with excellent control. This versatile profile excels at general cutting tasks while maintaining good piercing capability, making it perhaps the most common design in modern folding knives. The Benchmade Griptilian and Spyderco Endura exemplify this popular profile.
Clip Point: Characterized by a concave curve or straight line that “clips” away from the spine toward the tip, creating a thinner, sharper point. This design enhances piercing ability while maintaining good slicing capability. The Buck 110 and Spyderco Military represent iconic implementations of this classic profile.
Tanto: Features an angular transition near the tip rather than a curved belly, creating a reinforced point. Cold Steel popularized this profile in folding knives, while modern interpretations appear in models like the ZT 0301 and Microtech Socom Elite. The design prioritizes tip strength for penetration through tough materials.
Wharncliffe: Presents a straight edge with a spine that curves downward to meet it at the tip. This design places the point in line with the handle for precise control and eliminates belly sweep that might cause unwanted cutting. The Spyderco Yojimbo 2 and CRKT Pilar showcase this specialized profile.
Trailing Point: The spine curves upward to create a pronounced “belly” along the edge, maximizing cutting surface. This design excels at slicing tasks but typically produces a relatively delicate tip. Hunting-oriented folders often feature this design, as do many traditional slip joint patterns.
Sheepsfoot: Presents a straight edge with a blunted spine that curves sharply downward at the end. This design prioritizes controlled cutting while minimizing accidental piercing, making it popular for rescue knives and sailing applications. The Spyderco Rescue and Benchmade Proper exemplify this safety-oriented profile.
Spear Point: Features symmetrical edges that converge to a centered point, creating excellent piercing capability. Tactical folders and defensive designs often incorporate this profile, as seen in the Microtech Ultratech and certain Gerber models.
Blade and Handle Materials
Modern folding knives utilize advanced materials to balance performance, durability, and weight considerations:
Premium Blade Steels: CPM-S30V, CPM-S35VN, CPM-S45VN, CPM-S90V, M390, 20CV, and CTS-204P deliver exceptional edge retention, corrosion resistance, and toughness. These powder metallurgy steels appear in high-end offerings from Benchmade, Spyderco, Zero Tolerance, and other premium manufacturers.
Mid-Range Blade Steels: D2, 154CM, 14C28N, VG-10, and AUS-8 balance performance with cost considerations. These materials appear widely across price points from budget-conscious to upper mid-range folders. Civivi, Kershaw, and CRKT frequently employ these versatile steels.
Budget-Friendly Steels: 8Cr13MoV, 440C, and AUS-8 deliver adequate performance at accessible price points. Manufacturers like CRKT, Kershaw, and QSP utilize these materials in their economical offerings.
Handle Materials:
