Review: Benchmade’s 375-1 Fixed Adamas is ‘virtually indestructible’, lifesaver of a knife

If you could only have one knife to carry around in a survival situation, the Benchmade Fixed Adamas is a tough choice to beat.

Tough and lightweight, this beast of a bulletproof blade will be there when you need it, from tactical use to bushcraft. If you throw it in your bag, you won’t know it’s there, but you’ll be glad it’s there when you need it.

While Oregon-based Benchmade labels the Fixed Adamas a “tactical” knife – and it works great for military use due to its reputation for being indestructible – this knife will serve you in virtually any outdoor situation. Benchmade states that this knife is designed for hard and immediate use.

When hiking in the backcountry, hunting or surviving, the last thing you need is a heavy piece of steel weighing you down. The fixed Adamas weighs only 5.66 ounces, which is less than a can of beer. With the sheath that comes with it, you’re only looking at 6.77 ounces.

In short: Compared to the new Benchmade Mini Adamas, an excellent EDC record, the Fixed Adamas weighs only 2.17 ounces more. And for those extra few ounces, you get a knife tank. Machined from CPM-CruWear, Benchmade improved this classic knife in 2021making it even better.

It is a very nice knife. I had the cobalt black version and out of the box, you know this knife means business. The fixed Adamas is thin, elegant and very light. It has a skeleton handle but comes with paracord (96 inches!) to wrap it around if you want, which I did.

The sheath supplied with the Fixed Adamas fits very tightly to ensure the blade stays in place, and it has an elastic button strap to lock the knife in place. You can attach the low profile sheath to MOLLE webbing or a belt using the Malice clips that are also included.

As Benchmade is known for, the CPM-CruWear (63-65) the blade was razor sharp right out of the box. The Benchmade Fixed Adamas is ready for action the moment it’s in your hand.

While you might not want to fight a bear or a bobcat, you have a better chance with this knife at your side. Let’s say it’s hard.

I opted for the Adamas Fixed Benchmade for a light bush knife. I can throw it in my bag or clip it on a shoulder strap with the MOLLE compatible sheath. Carrying it around in the field apparently adds no weight, which was my goal with this piece of equipment.

A big part of the lightweight knife is the skeleton handle. It comes with four large holes in the flat, thin CPM-CruWear handle. When you wrap the handle with the provided paracord, it provides a bit more grip and comfort.

Benchmade has redesigned this knife to be even stronger and with the new CPM-CruWear they have done just that. The fixed Adamas also went with a drop point style blade, giving it a sleeker look. It still offers thumb and index finger ridges at the base of the blade to ensure a solid grip.

In the backcountry, this knife will do everything from chopping wood and plucking sticks to gutting fish and starting a fire with a farro rod. (We’ve done it all.) Essentially, the blade is designed for long, heavy use without the need to sharpen it often.

What it’s made of: CPM-CruWear Cobalt Black

So what exactly is CPM-CruWear? In short, this is the biggest update of the Fixed Adamaswhich makes the knife sharper and stronger.

Digging a little deeper into the details, the CPM-CruWear is a new type of steel which is more wear-resistant, tougher and has a higher attainable harness than D2 steel, according to the manufacturer.

Designed specifically to withstand heavy use and wear, the blade will maintain a sharp edge under the most brutal conditions. The side load breaking strength on the new 375FE-1 is about 15% stronger than the original 375. The blade’s bending strength is 1,218 inch-pounds and the tip breaking strength is 558 inch-pounds, according to Benchmade.

And that’s why Benchmade chose the CPM-CruWear, knowing the knife would be heavily used in environments where sharpening tools aren’t available. Users can rest easy knowing that it will hold an edge wherever they use it.

Conclusion

the Benchmade 375-1 Fixed Adamas is a great option for any scenario where you need a tough blade to save the day.

The only downside would be the MOLLE carrying system. While it works great if you have a MOLLE compatible bag, if you don’t or just want to carry it on your belt, it’s a bit bulky.

The sheath also locks the knife in very tight, which is good but can make it difficult to access it quickly. Luckily, the sheath tension is adjustable should you wish to loosen the grip.

Benchmade has improved what was already a great knife. Great for tactics, survival, bushcraft or just tossing in your bug out bag, this knife delivers.

The Fixed Adamas retails for $250 and is available in Cobalt Black or Flat Earth.
