Choosing a premium folding knife is often about finding the right balance.

Some knives focus heavily on aggressive styling. Others prioritize pure utility but sacrifice refinement and carry comfort. For many EDC users, the ideal knife sits somewhere in between — compact enough for daily carry, capable enough for real work, and refined enough to appreciate every time it comes out of the pocket.

The Gryvex Swordfish Knives S3101 was designed around exactly that philosophy.

Designed by Rattlesnake, the Swordfish combines a 3-inch Böhler M390 blade, titanium frame lock construction, and ceramic bearing deployment into a clean, modern folding knife built for users who appreciate performance without unnecessary excess.

After spending time examining its dimensions, materials, deployment characteristics, and carry experience, the Swordfish feels less like a flashy pocket knife and more like a purpose-built EDC tool.

First Impressions: Clean, Fast, and Refined

The first thing that stands out about the Swordfish is not size.

It is the shape.

The overall profile feels streamlined, almost as if every line intentionally pushes forward. The tapered titanium handle and clean blade profile create a visual flow that immediately feels fast and controlled.

Unlike oversized tactical folders that try to demand attention, the Swordfish takes a quieter approach.

It looks refined rather than aggressive.

For many EDC users, that is exactly the point.

Blade Performance: Böhler M390 Remains a Favorite for Good Reason

The Swordfish uses Böhler M390 steel, which has become one of the most respected premium blade steels among knife enthusiasts.

Blade Specifications

• Blade Steel: Böhler M390

• Blade Length: 3" (78 mm)

• Blade Thickness: 0.1259" (3.2 mm)

• Blade Width: 1.1" (28 mm)

• Hardness: HRC 60±1

• Blade Finish: Stonewashed

• Grind: Flat

M390 is known for delivering an excellent combination of:

• Outstanding edge retention

• Strong corrosion resistance

• High wear resistance

• Long-term durability

During practical use, a 3-inch blade length generally falls into one of the most versatile categories for EDC tasks.

Tasks such as:

• Opening packages

• Cutting cardboard

• Rope and cord work

• Food preparation

• General utility use

The flat grind geometry improves slicing efficiency and allows the blade to move through material with relatively little resistance.

The stonewashed finish also helps reduce visible wear over time.

Instead of showing every scratch, the blade develops a more natural used appearance that many enthusiasts actually prefer.

Handle Design: Titanium Without Excess Weight

The Swordfish uses a precision-machined titanium handle, giving the knife a premium feel immediately.

Handle Specifications

• Handle Material: Titanium

• Handle Length: 4.6" (112 mm)

• Handle Width: 1.26" (32 mm)

• Thickness: 0.46" (11.6 mm)

• Weight: 124.3g

Titanium remains popular in premium folding knives because it provides:

• High strength

• Corrosion resistance

• Lightweight performance

• Excellent structural rigidity

At 124.3 grams, the Swordfish carries enough weight to feel substantial but avoids becoming heavy in the pocket.

Some large titanium folders can feel bulky during all-day carry.

The Swordfish avoids that problem.

Real Carry Experience: Comfortable in the Pocket

Pocket comfort matters more than many users initially expect.

A knife that performs well but feels awkward to carry usually spends less time in the pocket.

The Swordfish dimensions create a balanced carry experience:

Overall Length: 7.6" (192 mm)

The profile remains slim enough for daily use while maintaining enough handle length for a secure grip.

The Titanium pocket clip sits naturally against the handle and keeps the knife secure without creating excessive tension.

For jeans, work pants, or casual everyday carry, the size feels practical rather than oversized.

Action Test: Ceramic Bearings Create Smooth Deployment

Action quality often separates premium knives from average ones.

The Swordfish uses a caged ceramic ball bearing pivot system, and this becomes noticeable immediately.

Opening action feels:

• Smooth

• Controlled

• Consistent

• Mechanical without feeling stiff

The deployment does not feel overly loose or excessively aggressive.

Instead, the blade rotates with a refined motion that feels intentional.

Many knife enthusiasts appreciate action that feels smooth and precise rather than fast simply for the sake of speed.

The Swordfish leans toward mechanical refinement.

Frame Lock Performance

The Swordfish uses a Titanium Frame Lock design.

Frame locks continue to remain popular among EDC users because they offer:

• Strong lock engagement

• Simple construction

• Slim profile

• Long-term reliability

During use, lock engagement feels solid and predictable.

There is minimal movement and the knife inspires confidence during harder cutting tasks.
