Knife Parts
The pocket knife, combines intricate design with multifunctional use through its carefully engineered parts. Each component, from the choil to the durable pocket clip, plays a pivotal role in the knife's overall performance and utility. This article showcases the anatomy of a pocket knife, highlighting the key parts such as the pivot mechanism, chamfer, and locking system. By understanding these elements, enthusiasts can make informed choices about their pocket knives, ensuring they select a tool that perfectly matches their needs and preferences. Whether for outdoor adventures, daily tasks, or as part of a collection, knowing the ins and outs of pocket knife components is essential for any knife user.
Blade And Handle
Barrel Spacer
A barrel spacer is a cylindrical or tubular-shaped component that is used to separate and maintain the spacing between the handle scales of a folding knife. Barrel spacers are often placed at various points along the back or spine of the knife, providing structural support and contributing to the overall design and functionality.
Choil
A choil is a small, unsharpened notch or recessed area located at the base of the blade, typically where the handles meet the blade. The choil serves several purposes and is found in various knife designs.
Chamfer
A chamfer refers to the beveled or angled edge that is intentionally created along the blade. This beveling is a critical aspect of knife design and affects its cutting performance, durability, and overall functionality.

Detent
The detent is a small component, often a ball or a protrusion, that interacts with the blade, creating friction and resistance at certain points in its movement.
Finger Choil
The finger choil provides a space for the user's index finger to rest comfortably when gripping the knife. It allows the user to choke up on the blade for more precise control during detailed or fine-cutting tasks.
Liner
A liner is a thin, flat piece of metal that is used in the construction of the knife’s handle. Liners serve various purposes in knife design, particularly in the construction of folding knives.
Lock
The lock is a mechanism that secures the blade in an open position, preventing it from accidentally closing during use.
Pin
Handle pins are used to secure the handle scales to the tang of the knife. They contribute to the structural integrity of the handle and help keep the knife's components securely in place.
Pivot
The pivot is a point at which the blade rotates when the knife is open or closed. The pivot is a crucial component of folding knives, as it allows the blade to move smoothly while maintaining stability and alignment.
Pivot Pin
A pivot pin is a cylindrical pin or rod that serves as the axis around which the blade rotates when the knife is opened or closed. The pivot pin is a critical component of folding knives, and it allows for the smooth movement of the blade.
Pivot Screw
A pivot screw is a screw or bolt that secures the pivot components of a folding knife. The pivot screw plays a crucial role in holding the knife's blade in place and allowing it to rotate around the pivot point.
Screw
Is a threaded fastener used to hold various components of the knife together. Screws play a crucial role in knife construction, providing a secure and adjustable means of joining different parts.
Stop Pin
A stop pin is a component that limits the movement of the blade within the handle. It serves as a physical barrier that prevents the blade from overextending or rotating beyond its intended range. The stop pin is a critical feature in the design of folding knives and contributes to their functionality and safety.
Tang
The tang is the portion of the blade that extends into or through the handle. The tang is an integral part of the knife's construction and plays a crucial role in determining the overall strength and durability of the knife.
Thumb Ramp
A thumb ramp on a knife refers to a raised area on the spine of the blade near the handle that is designed to provide a comfortable and secure platform for the user's thumb.
Thumb Stud
A thumb stud is a small, protruding knob or peg attached to the blade of a folding knife, near the base or spine. It serves as a manual opening mechanism, allowing the user to easily and quickly deploy the blade with one hand.
Washer
A washer is a thin, flat, circular component that is placed between the moving parts of a folding knife, typically between the handles and the blade.
Pivots
Blade pivots in folding knives can use various types of washers or bearings to facilitate smooth movement and reduce friction between the blade and the handle.
Bronze Washers
Bronze washers are traditional and have been widely used in folding knives. They are durable and provide a smooth action. However, they may require periodic lubrication to maintain optimal performance.
Bushings
The bushings are a cylindrical component that slides the pivot hole of the blade, allowing the blade to rotate on the center pivot point.
Caged Ball Bearings
Caged ball bearings are enclosed within a cage or retainer, which helps to maintain proper spacing and alignment between the bearings.
Channel Ball Bearings
Channel ball bearings are a milled channel within the blade that individual ball bearings rest in allowing for a smooth opening.
Teflon Washers
Teflon washers are made of a low-friction material that reduces friction between moving parts. Teflon washers are known for their smooth movement and resistance to corrosion. They are commonly used in modern folding knives.
Pocket Clips
Carabiner
A carabiner pocket clip is a versatile attachment that combines the functionality of a carabiner with a clip for convenient pocket carry. This design allows users to secure the knife to a belt loop, backpack, or other attachment points, offering easy access and portability. The carabiner feature adds an extra layer of utility, making it suitable for outdoor activities and everyday use
Deep
A deep pocket clip is an extended and often contoured metal attachment designed to allow the knife to be carried in a pocket with more of the knife concealed. This type of clip ensures a low-profile and discreet carry, keeping the majority of the knife deep within the pocket for enhanced concealment and comfort.
Milled
A milled pocket clip is a clip that has undergone a milling process, where the material is removed or carved to create a specific design or pattern. Milled pocket clips are crafted with precision and often feature intricate designs, adding a touch of aesthetics to the clip while maintaining functionality for secure pocket carry of the knife.
Standard
A standard pocket knife clip is a small, metal attachment affixed to the handle, allowing the knife to be securely fastened to the edge of a pocket. Typically made of stainless steel, it provides convenient and accessible storage while ensuring the knife remains readily available for everyday use.
Wire
Wire clips are often made from materials like stainless steel and titanium, allowing for a slim and low-profile design. This design minimizes the bulk and weight added to the knife, making it easier to carry discreetly in a pocket.
