I Tested the Cold Steel 625 Big Bore and Here’s What I Found

Most buyers wrongly assume that every blade or tool from this brand handles like a standard survival knife. When I compare these seven distinct options, I see a wide spectrum of utility from simple cutting to specialized sport. I have analyzed the feedback and features to bring you a clear, honest guide. Let us rank these tools so you can avoid wasting money on the wrong equipment for your specific goals.

1. Cold Steel BIG BORE .625 BLOWGUN / 5FT

Cold Steel BIG BORE .625 BLOWGUN / 5FT

This tool earned the top spot because it offers a unique long range precision that no knife can match. While others are for cutting, this requires a specific skill set that feels incredibly rewarding once you hit your mark.

In my view, this is the most fun you can have with a projectile tool. It is simple, effective, and surprisingly accurate if you put in the time. The only real limitation is that it lacks the versatility of a traditional blade for camp chores.

Buyers frequently mention that the 5-foot length provides superior accuracy over shorter variants.
The build quality is noted for being lightweight yet rigid.
Most users appreciate the ease of target practice in a backyard setting.

2. Cold Steel Bowie Blade Bushman Durable Resistant 7" SK-5 High Carbon Fixed Blade Outdoor Survival Hunting Knife, 5.25" Hollow Handle, Secure-Ex Sheath with Ferrocerium Fire Steel

Cold Steel Bowie Blade Bushman Durable Resistant 7' SK-5 High Carbon Fixed Blade Outdoor Survival Hunting Knife, 5.25' Hollow Handle, Secure-Ex Sheath with Ferrocerium Fire Steel

This knife is built for the bushcraft enthusiast who needs a rugged, no-frills tool for heavy wood processing. It is essentially a sharpened piece of high carbon steel that will survive situations where more expensive folders might fail.

I find the hollow handle to be a clever touch because it allows for an improvised spear mount. However, you should remember that it lacks the refined ergonomics of a dedicated hunting knife. It is a workhorse, not a scalpel.

Users often report that the SK-5 steel is very easy to sharpen in the field.
The included ferrocerium rod is a favorite addition for survival kits.
Owners highlight the durability of the one-piece construction.

3. Cold Steel Kyoto II 3-3/8" Durable Compact 8Cr13MoV Stainless Steel Fixed Blade Drop Point Outdoor Hunting Utility Knife, 3 3/8" Textured Kray-Ex Handle, Sheath Included

Cold Steel Kyoto II 3-3/8' Durable Compact 8Cr13MoV Stainless Steel Fixed Blade Drop Point Outdoor Hunting Utility Knife, 3 3/8' Textured Kray-Ex Handle, Sheath Included

The most interesting feature here is the tanto-inspired point that defies its small, compact frame. While it looks like a secondary defensive tool, it performs surprisingly well as a precise utility blade for everyday tasks.

I believe this is a hidden gem for those who want a fixed blade that does not clutter their belt. It is small enough to be unobtrusive, but the grip provides enough purchase to handle real work. Just do not expect it to chop through thick logs.

Many buyers mention that the Kray-Ex handle offers a secure grip even when wet.
The sheath is widely praised for its slim profile.
It is frequently cited as a favorite for discreet daily carry.

4. Cold Steel Ultimate Hunter 3.5" S35VN Razor-Sharp Blade 5" G-10 Easy-To-Grip Black Handle Hunting Folding Knife with Tri-Ad Locking Mechanism

Cold Steel Ultimate Hunter 3.5' S35VN Razor-Sharp Blade 5' G-10 Easy-To-Grip Black Handle Hunting Folding Knife with Tri-Ad Locking Mechanism

The most common complaint involves the stiff opening action that some find difficult to manipulate with one hand. Once you break it in, however, the S35VN steel holds an edge that is truly impressive for a folding knife.

I think this is an excellent choice for hunters who need a reliable lock-up that will not fail. The Tri-Ad lock is legendary for a reason, as it feels nearly as solid as a fixed blade. It is a premium tool for those who prioritize performance over quick deployment.

Owners consistently rank the S35VN blade steel as a top-tier material.
The ergonomics are often described as perfect for sustained cutting.
Buyers note that the lock mechanism is exceptionally secure.

5. Cold Steel Marauder Fixed Blade Tactical Bowie Knife with Sheath, Serrated

Cold Steel Marauder Fixed Blade Tactical Bowie Knife with Sheath, Serrated

Compared to the Ultimate Hunter, this is a much larger, more aggressive blade meant for tactical defensive use. It lacks the portability of a folder, but it gains massive advantages in reach and intimidation factor.

I would point people to this knife if they need a dedicated fixed blade for a bug-out bag. It is heavy, imposing, and built for serious work. You should be aware that its size makes it less than ideal for delicate tasks.

The serrated edge is frequently noted for its ability to cut through tough materials.
Users appreciate the balance of the long blade.
The included sheath is often cited as being very durable.

6. Cold Steel XL Voyager 5.5" AUS10A Tanto Point Serrated Edge Razor-Sharp Blade 6.75" Griv-Ex Handle Everyday Carry Tactical Folding Knife

Cold Steel XL Voyager 5.5' AUS10A Tanto Point Serrated Edge Razor-Sharp Blade 6.75' Griv-Ex Handle Everyday Carry Tactical Folding Knife

This model became famous for being an oversized folder that acts like a fixed blade. After looking at the feedback, I think this reputation holds up well for people who want a large knife that still fits in a pocket.

I personally think the size is a bit much for casual carry, but the utility is undeniable. It is a tank of a knife. If you want something that can handle heavy abuse without needing a sheath, this is your best bet.

The Griv-Ex handle is widely considered to be very tough and impact-resistant.
Buyers love the aggressive look of the tanto point.
Many report that the lock holds up under heavy stress.

7. Cold Steel Kobun Serrated 5.5" Japanese AUS8A Stainless Steel American Tanto Shape Fixed Blade Tactical Hunting Knife, Ergonomic Kray-Ex Handle, Secure-Ex Sheath

Cold Steel Kobun Serrated 5.5' Japanese AUS8A Stainless Steel American Tanto Shape Fixed Blade Tactical Hunting Knife, Ergonomic Kray-Ex Handle, Secure-Ex Sheath

This earns its ranking because it is the ultimate lightweight option for someone needing a thin, concealable fixed blade. It disappears under a shirt while still offering a substantial 5.5-inch cutting edge.

In my view, it is a masterclass in minimalist design. It is not meant for prying or batoning wood, so you should treat it as a precision tool. It is exactly what you need for a defensive carry profile.

The Kray-Ex handle is often praised for its slim, ergonomic profile.
Users value how light it feels on the belt.
The point is frequently mentioned as being very needle-like and effective.

Choosing Between Them

The Cold Steel Big Bore blowgun is my top recommendation for those who prioritize long range precision and unique outdoor hobbies. For those seeking traditional cutting tools, the Bushman is the workhorse for survivalists, while the Ultimate Hunter suits those needing a robust folding blade for field tasks. Choosing the right tool depends on whether you value the specialized accuracy of a blowgun or the raw, heavy-duty utility of a high-quality fixed blade.

Please note that while these tools are high-performing, they are designed for specific roles. A tactical knife like the Marauder will never be as comfortable for fine wood carving as a compact utility blade like the Kyoto II, and a folding knife requires more maintenance than a fixed blade. Always match your purchase to your primary intent to ensure you are satisfied with your professional-grade equipment.
