So when I heard the Marten was returning, and this time in a larger format, I was definitely interested. Don’t get me wrong, sub-3-inch knives have their place and they’re great for a lot of situations. But my personal sweet spot sits right around that 3¼-inch mark. The Marten 330 lands very close to that at 3.30 inches. Hold up… that’s where the model name comes from. Sometimes the obvious things take a second to click.

Today we’re taking a look at the Marten 330 and what makes this larger version stand apart from the original design.


Handle and Comfort

Sizing the knife up means you’ve got more real estate for your mitts. The original handle measured 3.81 inches, while the Marten 330 stretches that out to 4.27 inches. That’s nearly half an inch of extra handle, which is enough to keep that wayward pinky from hanging off the edge.

The overall handle shape hasn’t changed, and that’s a good thing. The design includes a generous forward choil that gives you plenty of room to work with. The finger groove is large enough that two fingers can comfortably sit in that space. It adds a lot of confidence during controlled cuts and still feels natural when choking up.

The Marten 330 comes in a few different handle textures, and the one I have features the criss-cross diamond milling pattern. I was drawn to this version because it’s completely different from the diagonal milling used on the original Marten.

The texture itself has subtle peaks and valleys that feel great in the hand while also creating a strong visual dynamic. It’s not overly aggressive, but it provides plenty of traction when you’re actually using the knife.

There’s jimping along the spine and on the backspacer where the handle meets your palm. Together it all creates a grip that feels secure and controlled without feeling abrasive.


Lock and Carry

The Marten 330 utilizes Vosteed’s Top Liner Lock, or TLL. These locks are all the rage right now, and we’re seeing more companies experimenting with the concept or even adding it to existing designs.
At its core, the TLL combines the simplicity of a liner lock with the convenience of button actuation. Pressing the button pushes the liner aside so the blade can close. The key difference is placement. Instead of the liner lock being positioned at the bottom of the handle like a traditional liner lock, this one sits at the top.

That small change brings a couple of advantages. For one, it keeps your fingers safely out of the blade path when you disengage the lock. It also tends to create a stronger lock interface. Between this and cross-bar style locks, it’s easily one of my favorite mechanisms.

When it comes to the pocket clip, there’s nothing fancy going on here, and honestly I like that. I enjoy premium titanium clips as much as the next knife guy, but sometimes simple just works.

Vosteed has built a reputation for making excellent deep-carry clips. They may tweak the design slightly between models, but the overall concept remains consistent. The clip rides deep in the pocket without making the knife difficult to retrieve. There’s just a tiny bit of the handle peeking out, but not enough to scream “hey, this guy’s carrying a knife.”

The spring tension feels dialed in nicely as well. The knife stays secure in the pocket without feeling like it’s trying to escape like a convict every time you sit down. Best of all, the clip doesn’t create any hot spots during use.


Blade and Performance

When it comes to stretching steel, the Marten 330 bumps the blade length up from 2.98 inches to 3.30 inches. That’s a noticeable increase and enough to give the knife a more capable feel without pushing it into oversized territory.

The blade uses a drop point profile, which is one of the most practical shapes you can have for everyday carry. The tip is nicely pronounced, making it easy to initiate cuts, while the belly provides smooth slicing through longer material.

The grind isn’t technically a full flat grind, but it’s close enough that it performs very similarly. It strikes a nice balance between slicing performance and structural strength.

Steel choice is 154CM, which has been around for over 50 years and still holds its place as a respected blade steel. It offers a well-balanced combination of edge retention, corrosion resistance, and ease of maintenance. Even with all the new steels appearing on the market, 154CM remains a dependable option that continues to earn its keep.

Deployment is handled through thumb studs, and these are very well executed. They’re a comfortable diameter that makes thumb placement easy without feeling bulky or getting in the way.

The detent deserves some praise as well. It’s dialed in just right. There’s enough retention to keep the blade closed without any funny business, but once you apply pressure the blade snaps open with authority. It’s the kind of action that makes you want to flick it open again and again.

Final Thoughts

The Marten 330 feels like the natural evolution of the original design. It’s what happens when people say “this knife is great… but can we get just a little more of it?”

The larger blade and extended handle give the knife a more substantial feel while still keeping the overall package easy to carry. Vosteed has done a great job making efficient use of the added space without letting the knife grow out of control.

If you missed out on the original Marten and prefer something with a bit more blade and handle to work with, the Marten 330 lands in a very comfortable middle ground. For a lot of people, it’s going to hit that everyday carry sweet spot nicely.
