A pocket knife is a type of folding knife that can be conveniently carried in a pocket. There are many advantages to owning a pocket knife, from its versatility and ease of use to its rich history.

Parts: A pocket knife typically consists of the following parts: blade, handle, back spring, pivot pin or rivet, locking mechanism, and bolsters (if applicable).

The blade is the most important and practical part of any pocket knife, as this is the tool used for cutting or slicing items. It can also feature shapes or expressions such as “spear point” or “drop-point” blades, which can be serrated or plain edged.

The handle holds all of the parts together and serves as a protective cover for your fingers when using the knife. Handles can be made from various materials such as plastic, leather, wood, aluminum, G10 scale material and more.

The back spring is responsible for keeping the blade open when in use and closed when not in use. The backspring will partially protrude through an opening on one side of the handle when engaged.

The pivot pin or rivet holds everything together by connecting each side of the handle to the blade’s tangs with a strong fastener that allows you to rotate it open and closed smoothly with one hand.

On some models, there may also be a locking mechanism designed to prevent accidental closure when in use. Typically this will either involve a lock bar running along one side of both handles that must be disengaged before being able to close it completely; or alternatively have a plunger-style operative located on one side that must be pushed down into order to shut it down safely.

Lastly if applicable some folding knives also have bolsters located between each end of the handle adjacent to the blade which provide strength and protection against wear over time while enhancing the grip with their additional surface area design grip patterning on their faces at times – allowing you both superior level gripping comfort even during heavy duty applications (outdoor activities).

Types of Blades

A folding pocket knife typically consists of two main parts – the handle and blade. The handle is usually made from wood, metal, plastic, or bone and can also feature gripping inserts. As for the blades, there are various types that can be found on a pocket knife.

The most common type of blade is the drop point, which features a curved spine with an angular tip. Drop point blades generally have thicker edges with sharper tips and are excellent for hunting tasks. Another popular blade style is the clip point. Clip points blades have a thinner shape with a sharply angled cutting edge which makes it suitable for tasks that require precise cuts or piercing.

The length of the blade plays a role in what tasks the knife can be used for – short blades (under 3 inches) make ideal everyday carry (EDC) knives while longer blades provide more precision to tackle tougher job such as bushcrafting or skinning. Serrated blades also come in various styles to further increase versatility – standard sharpening sawteeth can power through tough material while still having its sharpness intact unlike straight edged ones which need frequent sharpening due to their wear-resistant properties.

Pocket Knife Handles

Pocket knife handles come in a variety of materials and styles. Common materials used for pocket knife handles are wood, metal (scales) and synthetic materials. The type of material determines how the knife feels in your hand and how much grip it provides for you when using it.

Wooden handles are often sought after for their artistic appearance options due to the unique grain patterns each one produces. They tend to be lightweight, but can be difficult to keep clean and maintained over time as dirt, dust and other particles build up from regular usage. Furthermore, wooden knife handles will require more maintenance as they are susceptible to moisture damage.

Metal scales, also known as liners, provide an equally stylish look while providing increased durability against wear and tear as well as stable temperatures than wooden or synthetic knives. Different types of metal scales include stainless steel, titanium and aluminium alloys, which create a heavier solution than wooden handles or plastic glued liners but ensure a lasting product that is resistant to abuse.

Synthetic material knives offer lightweight portability while still having some degree of durability like metal scales but they tend to feel somewhat slippery in your hand if gripping hard enough to put much pressure on the blade when working with something durable such as rope knots or fibrous tree branches. Common synthetic materials used in pocket knife handles today include thermoplastic polymers such as Kraton G which offers superior resistance against shattering and cracking due to its flexible properties compared to other rigid plastics. Other popular synthetic materials include G-10 fiberglass composite laminate which comes in different thicknesses offering a more muscular feel in the hand than traditional metals; Micarta, CTek carbon-fiber composite material created from layers of woven fibers which provides excellent corrosion resistance; Micarite composite made from textured polymer epoxies; Valox PBT-GF40 nylon resin offering optimal impact strength; Richlite paper composites being heavy duty laminate paper that is extremely hard wearing and durable; Antron nylon based on its fire retardant properties offering superior resilience; Anodized aluminum boasting excellent abrasion-resistance along with a polished finish available in many colors, plus Zytel ST801 polymer giving improved stiffness over traditional plastics while still remaining light weight yet strong enough not to corrode nor rot over time.

Fasteners and Locking Mechanisms

A folding pocket knife has many parts, and understanding how each of them works together is essential to safely opening and closing the knife. The two main fasteners are the back spring or lock spring and the blade tang. Both work together to keep the blade in place when the knife is open and to secure it shut when it’s closed.

The back spring is located at the base of the handle, near where your thumb would go if you were using the knife. This piece works like a latch, holding both sides of the handle tightly against one another when activated with pressure. Usually this pressure is applied by pushing down on a small lever or button near the base of the blade on one side of the handle while simultaneously lifting up on a second lever or button from typical opposite side of the handle. Releasing these levers will allow you to pull apart and open one part of the handle from another so that you can reach and access your blade.

The other fastener, called a blade tang, extends from the end of your knife’s blade and connects it to its handles so that when extended uses tension as a locking mechanism for keeping both pieces attached even more securely than just relying on friction alone. If your pocketknife does not possess any external levers or buttons but still has a foldable design you will typically want to put gentle pressure (not too much though!)on both sides around where your fingers will usually grip because chances are that’s where it’ll have some sort of internal sliding lock mechanism meant to keep everything locked into place too.


When it comes to folding pocket knives, you can customize the specifics to make it an entirely unique item that’s tailored for your own needs. Depending on what type of folding pocket knife you choose, you may be able to switch up different parts of the knife. The following are some common parts which can be customized or swapped depending on the style of pocket knife you have:

1. Handle: One of the most commonly customizable features is the handle itself. It might come in plastic or metal, but both versions allow you to switch out colors or add in custom designs (like engraving) to create a personalized look that’s all your own.

2. Blade: Another feature that can be customized are the blade types and styles available. From a sharp serrated edge to a plain edge – there’s virtually a wide range of possibilities when it comes to finding something that fits your every need.

3. Lock Mechanism: The lock mechanism refers to how firmly secured the blade is onto its base when not in use and stored away safely inside your pocket. Different types of locks will provide stronger security, such as liner locks and framelock styles. Selecting one that provides more resistance against movement will prevent accidental opening when carrying and storing away your folding pocket knife safely.

4. Pocket clip: Lastly, if the style allows for it – you can select from a wide array of colors with different designs (like those made from screw-on attachments) for additional personalization of your folding pocket knife! However, when choosing a clip, find one that is durable yet lightweight so that clips securely without weighing down your pockets too much!.


When it comes to folding pocket knives, it is important to regularly clean and maintain them in order to keep their parts in good working order.

Blade: To start, use a soft cloth and Mild Detergent to gently clean the cutting edge of the knife and then dry thoroughly with a dry cloth or paper towel. Apply a thin layer of oil on the blade and pivot areas both inside and outside to prevent rust. It is also important to check for any nicks or marks on the blade, as those can slow down performance.

Pivot: Keep dirt and debris away from the knife’s pivot by blowing air into the crevices, moving it around in circular motions occasionally with a toothpick, or using compressed air if you have access to it. Oiling this area can help lubricate it as well as keep dirt from building up.

Screws: Screws should be checked monthly for tightness because all that use weakens them over time. Oil screws periodically with an appropriate oil such as WD-40 so they don’t get rusty or stripped when unscrewing them too hard. Additionally, be sure not to overtighten them after use because this can damage the threading.

Handle Material: Over time, handle material may require some maintenance depending on what type of material it is made out of (wood, composite material) in order for the surface finish to look its best. Handle material should be wiped down with a damp cloth and then treated with linseed oil periodically if needed in order restore its natural luster or remove blemishes.

DIY Projects

A pocket knife is a great tool to have in your arsenal for any number of tasks. From camping trips to everyday tasks, having a knife handy can be convenient. If you own a folding pocket knife, the following are some parts that can make it work efficiently:

Blade: This is the most recognizable part of a pocket knife and is generally used for cutting and slicing. Blades come in different sizes and styles depending on what type of knife you have purchased.

Spring/Lock Mechanism: This is the piece that helps keep the blade extended when opened and retracted when closed. Different types of knives may use a ball bearing lock or frame lock mechanism to ensure safety when closing the blade.

Handle/Scales: The handle will vary in both look and feel among different kinds of knives but all provide comfort while using it. Generally, they are created with material such as G-10, stainless steel or wood scales to resist slip and adding durability against wear and tear over time.

Fastening/Pocket Clip: A pocket clip keeps your knife readily accessible at all times while also keeping it secure in your pocket or belt loop where ever you go. Having this feature makes it easier to access your knife quickly instead of digging around for it in your bag or pack.
