Cold Steel Oyabun Folding Knife Review

First Impressions of Cold Steel Oyabun Folding Knife

The Cold Steel Oyabun Folding Knife immediately grabs your attention with its tanto blade and aggressive styling. From Cold Steel, a brand known for its robust and practical designs, the Oyabun promises a blend of tactical functionality and everyday carry convenience. It’s a knife that seems ready for anything, and I was eager to see if it lived up to that initial impression.

I was looking for a reliable and durable folding knife that could handle various tasks, from opening boxes to more demanding outdoor chores. My search centered around finding a blade with a strong lock, comfortable grip, and a blade shape suitable for both piercing and slicing. I wanted something that felt substantial without being overly bulky, a true do-it-all tool.

The Cold Steel Oyabun arrived in standard packaging, nothing fancy, but opening it revealed a knife that felt solid and well-built. The Griv-Ex handle provided a secure grip, and the blade deployed quickly and smoothly thanks to the flipper mechanism. Its weight felt just right, not too heavy to be cumbersome, but enough to inspire confidence.

Compared to my Benchmade Griptilian and Spyderco Paramilitary 2, the Oyabun has a distinctly different feel. The Griptilian is lighter and more streamlined, the Paramilitary 2 offers superior slicing performance, but the Oyabun feels like the tougher, more heavy-duty option of the three. I ultimately chose the Cold Steel Oyabun for its combination of strength, affordability, and unique tanto blade shape.

My first impression was one of cautious optimism. The Cold Steel Oyabun Folding Knife looked and felt promising, but the real test would be how it performed in the field.

Real-World Testing: Putting Cold Steel Oyabun Folding Knife to the Test

First Use Experience

I took the Cold Steel Oyabun on a weekend camping trip in the nearby mountains. I used it for various tasks, including preparing food, cutting rope for setting up my tent, and whittling some kindling for the campfire. The knife performed admirably, providing a secure grip even with slightly damp hands.

The Oyabun’s blade held its edge surprisingly well when cutting through cardboard boxes and rope, despite the initial factory edge not being razor-sharp. The weather was mild, but there were a few moments with light rain and the Kray-Ex overmold offered reassuring grip even under wet conditions. It felt comfortable in hand and didn’t cause any hotspots during prolonged use.

I did notice that the flipper required a bit more force than other flipper knives I own. It wasn’t difficult to deploy, but the action wasn’t as effortless as some.

Extended Use & Reliability

After several months of regular use, the Cold Steel Oyabun has proven to be a reliable and durable tool. I’ve used it for everything from daily tasks around the house to more demanding jobs on the trail. The blade still locks up tight, with no noticeable play.

The Griv-Ex handle shows no signs of cracking or chipping, even after being subjected to some fairly rough handling. The 4034 stainless steel blade has resisted corrosion well, even with minimal maintenance. I sharpen it occasionally with a ceramic rod, and it quickly returns to a usable sharpness.

Compared to my previous EDC knife, a Kershaw Leek, the Oyabun is significantly tougher and more capable of handling heavier tasks. However, the Leek is smaller and lighter and therefore disappears more easily in the pocket. The Oyabun is a step up in durability, even if you sacrifice a bit of comfort in your pocket.

Breaking Down the Features of Cold Steel Oyabun Folding Knife

Specifications

• The Cold Steel Oyabun Folding Knife boasts a 3.5-inch blade made of 4034 stainless steel. This material provides a good balance of edge retention, corrosion resistance, and ease of sharpening.
• The overall length of the knife is 8.25 inches, with a closed length of 4.75 inches. This size makes it reasonably portable for everyday carry, without sacrificing too much cutting power.
• It weighs in at 4.1 ounces. This is light enough for comfortable carry.
• The blade has a tanto shape with a high satin polish. This gives it a distinct tactical look and enhances its piercing capabilities.
• The handle is made of a Griv-Ex foundation over molded with Kray-Ex. This combination provides a comfortable and secure grip, even in wet conditions.
• The blade thickness is 3.8 mm. This provides excellent strength and durability.
• It features a leaf spring lock and safety, similar to that found on the Crawford 1 folder. This lock is known for its strength and reliability.

These specifications translate to a knife that’s well-suited for a variety of tasks, from everyday cutting chores to more demanding outdoor activities. The tanto blade is particularly effective for piercing and detail work, while the robust construction ensures that it can withstand plenty of abuse. The strong lock and secure grip inspire confidence when using the knife in challenging situations.

Performance & Functionality

The Cold Steel Oyabun Folding Knife performs its intended job admirably. The blade is sharp enough for most everyday tasks, and the tanto shape makes it particularly well-suited for piercing and cutting through tough materials.

The lock is solid and reliable, providing a sense of security when using the knife. The handle is comfortable to grip, even for extended periods.

One minor weakness is the flipper mechanism. While functional, it requires more force than some other flipper knives. It meets expectations for a robust and reliable tool, but it’s not the smoothest or fastest-opening knife on the market.

Design & Ergonomics

The Cold Steel Oyabun Folding Knife has a distinct tactical design. The tanto blade, high satin polish, and black handle give it a serious, no-nonsense look.

The Griv-Ex handle is well-shaped and provides a comfortable and secure grip. The checkering on the Kray-Ex overmold further enhances grip, even in wet conditions. There’s a slight learning curve with the flipper, but it becomes intuitive with practice.

Durability & Maintenance

The Cold Steel Oyabun Folding Knife is built to last. The 4034 stainless steel blade is resistant to corrosion, and the Griv-Ex handle is tough and durable.

Maintenance is simple. Regular cleaning and occasional sharpening are all that’s needed to keep the knife in good working order. With proper care, the Oyabun should provide years of reliable service.

Accessories and Customization Options

The Cold Steel Oyabun Folding Knife doesn’t come with many accessories. It includes only the knife itself.

There are no readily available aftermarket parts for the Oyabun, such as different scales or pocket clips. Due to its unique construction, it is unlikely to be easily customizable. This might disappoint those who enjoy tinkering with their knives. However, its robust design means it likely won’t need any modifications out of the box.
