Blade Steels

Each material possesses unique chemical and physical properties, and understanding your blade's characteristics can help you make informed choices.

Steel Composition

Blade Hardness: What Does This показатель Mean?

Blade hardness is one of the most important knife characteristics. It shows how resistant the steel is to wear, deformation, and edge dulling. Hardness is usually measured using the HRC scale (Rockwell Hardness Scale).

Simply put: the higher the HRC value, the longer the knife keeps its sharp cutting edge.

How to Understand Hardness Ratings?

Most modern knives have hardness levels between 54 and 64 HRC.

• 54–57 HRC — softer steel, easy to sharpen, handles impact well, but loses sharpness faster.
• 58–60 HRC — the best balance between strength, wear resistance, and ease of sharpening. The most popular choice for EDC and outdoor knives.
• 61–64 HRC — hard premium steel, keeps its edge for a long time, but is harder to sharpen and may be more brittle under heavy side loads.

How Does Hardness Affect Your Choice?

The right choice depends on how you plan to use the knife:

• For everyday carry (EDC), medium hardness is usually the best option — practical and reliable.
• For heavy-duty work, bushcraft, or hard use, slightly softer steel can be better because it is less brittle.
• For premium, collector, or maximum-performance cutting knives, higher hardness is often preferred.

Important to Remember

Higher hardness does not always mean better.

A blade that is too hard can become brittle, while a blade that is too soft may lose sharpness too quickly.

The ideal knife is a balance between hardness, toughness, and your real-world usage needs.

That is why, when choosing a knife, it is important to look not only at the brand or design, but also at the blade hardness rating.

Drop Point

Description: The spine smoothly slopes down toward the tip, which is aligned with the centerline of the blade.
Purpose: The most versatile shape. Great for slicing and piercing, with a strong tip.

Clip Point

Description: The spine has a straight or concave cut toward the tip, making it very sharp.
Purpose: Excellent for piercing and detailed work.

Trailing Point

Description: The tip is positioned above the spine line.
Purpose: Offers a long cutting edge, ideal for slicing and skinning.

Tanto

Description: The tip has an angular, clearly defined shape inspired by Japanese swords.
Purpose: Very strong tip, well-suited for piercing hard materials.

Sheepsfoot / Wharncliffe

Description: Straight cutting edge with the spine curving down to meet it.
Purpose: A safe cutter, commonly used in utility knives.

Spear Point

Description: A symmetrical, dagger-like shape with the tip centered and both spine and edge tapering evenly.
Purpose: Best for piercing.

Knife Opening Mechanism: What Does It Mean?

The opening mechanism defines how a folding knife moves from the closed position to the open, ready-to-use state. It is one of the key features of folding knives, directly affecting speed, convenience, and tactical usability.

In simple terms: it is how you open the knife — manually, with a thumb stud, flipper tab, hole opener, or an automatic system.

Main Types of Opening Mechanisms

There are several common ways folding knives are opened:

• Nail Nick — a classic manual opening method using the fingernail. Simple and reliable, but slower.
• Thumb Stud — a small stud on the blade that allows one-handed opening with the thumb. Fast and convenient.
• Thumb Hole — a signature solution used by some brands, enabling smooth one-handed opening from multiple positions.
• Flipper Tab — a blade protrusion activated by the index finger. One of the fastest and most popular modern systems.
• Automatic / Assisted Opening — the blade deploys via a button or mechanism. Maximum speed and ease of use.

How the Opening Mechanism Affects Your Choice

Your choice depends on how you plan to use the knife:

• For everyday carry (EDC), speed and convenience matter most — flipper and thumb stud are popular choices.
• For tactical or versatile use, thumb holes or hybrid systems are preferred.
• For traditional or collectible knives, nail nick opening is common.
• For fastest deployment, automatic systems are used.

Important to Consider

The faster the opening mechanism, the more important a strong lock and solid construction become. In some regions, automatic opening knives may also be legally restricted.

A well-chosen opening mechanism improves not only convenience, but also safety and overall performance in real-world use.

Lock Type: What Does It Mean?

The lock type defines the mechanism that secures the blade in the open position. It is responsible for user safety by preventing the blade from accidentally closing during use.

In simple terms: it is the system that keeps the knife locked open under pressure.

Main Types of Folding Knife Locks

There are several common lock mechanisms used in folding knives:

• Liner Lock — a metal liner inside the handle locks the blade in place. Lightweight, practical, and very popular for EDC knives.
• Frame Lock — part of the handle itself acts as the locking mechanism. Stronger and more robust.
• Back Lock — a spine-mounted locking system. Known for its durability and reliability.
• Button Lock — the blade is locked and released using a button. Fast and very convenient.
• Crossbar Lock (Axis-style lock) — a modern ambidextrous system with smooth operation and high strength.
• Slip Joint — does not lock the blade rigidly but provides resistance. Common in traditional or urban knives.

How Lock Type Affects Your Choice

Your choice depends on how you plan to use the knife:

• For everyday carry (EDC), Liner Lock and Crossbar Lock are popular due to their balance of safety and convenience.
• For heavy-duty tasks, Frame Lock and Back Lock are preferred for their strength.
• For fast and intuitive use, Button Lock is ideal.
• For traditional or lightweight urban knives, Slip Joint is commonly used.

Important to Know

Stronger locks generally provide higher safety under load. However, usability, one-handed operation, and overall ergonomics are just as important.

The right lock type directly impacts the knife’s safety, comfort, and long-term reliability.

Pocket Clip: What Does It Mean?

A pocket clip is a component attached to the handle of a folding knife that allows it to be securely carried on a pocket, belt, or gear. It directly affects carry comfort, accessibility, and how visible the knife is when clipped.

Simply put: the clip determines how the knife sits in your pocket and how quickly you can access it.

Main Types of Pocket Clips

Clips differ in design and carry style:

• Deep Carry Clip — the knife sits deep in the pocket, with minimal visibility.
• Standard Carry Clip — part of the handle remains visible above the pocket.
• Wire Clip — lightweight, flexible, and minimalistic.
• Solid Clip — traditional rigid metal clip, more durable.
• Reversible Clip — can be switched for left- or right-handed carry.
• Multi-position Clip — allows different mounting options (tip-up / tip-down, left/right).

Clip Materials

• Stainless Steel — the most common, durable and reliable.
• Titanium — lightweight, strong, and premium.
• Aluminum — lightweight but less resistant to bending.

How the Clip Affects Your Choice

The clip plays a key role in everyday usability:

• For EDC, discreet carry is important — deep carry clips are preferred.
• For quick access — standard carry or stiffer clips.
• For left-handed users — reversible or multi-position clips.
• For minimal weight — wire clips.

Important to Consider

A good clip should securely hold the knife, avoid damaging clothing, and allow quick deployment.
Choosing the right clip significantly improves comfort and usability in everyday carry scenarios.
