When we designed the Montana Knife Company™ Flathead Fillet Knife our goal was to create a knife that could do any possible task on the boat, next to the river or on the processing table. 

The Flathead Fillet got its name from the Flathead River, Lake, and Valley in the far northwest corner of Montana. The Flathead lake is known for being one of the largest and deepest lakes west of the Mississippi River, with some of the largest known lake trout.

MAGNACUT STAINLESS STEEL
MAGNACUT Stainless Steel

As a cryogenically heat-treated stainless steel, MAGNACUT provides the perfect blend of toughness, edge retention, and corrosion resistance.

Unlike other stainless steel blades, MAGNACUT can be easily resharpened — even by novice knife owners. More wear-resistant than other stainless steels, and more corrosion-resistant than carbon steel, MAGNACUT is in a class of its own.Learn more about MAGNACUT Stainless Steel from the creator: Larrin Thomas.
Versatile Blade Shape

The Flathead Fillet has the perfect balance of flex and rigidity.

The blade is designed to be flexible enough to work on your fresh catch on the side of the lake but rigid enough to help you process your elk or deer in your garage.

Black PVD Blade Coating

The Black PVD coating gives the knife a sleek finish and also has a practical purpose.

The blade is also PVD coated to a matte black finish, which makes the Flathead Fillet easy to clean and resistant to rust and wear.

Bulletproof G-10 Handle Scales

The G-10 handle scales are equally as tough as the blade. G-10 is famous for being strong, durable, and lightweight — unmatched by any natural handle material.

It can withstand any abuse without cracking or breaking, won’t absorb blood, and provides excellent grip, even when wet. The contours of the handle are also designed for comfort in extended use. The G-10 scales are attached with locally sourced titanium screws and high-strength epoxy to secure the perfect, lasting fit.

The sheath features a built-in retention screw to customize blade tension and allow for handle-down carrying. The Flathead Fillet sheath comes with a Kydex clip allows you to carry your knife on a pack or belt loop, either horizontally or vertically.

    Great Fillet Knife

    The Flathead Fillet is a great blade. I’ve used it to process a deer so far. Can’t wait to go fishing. It’s also a nice addition to my culinary setup.

    Slicey

    A little stiffer than I’m used to using but overall it did a great job of cleaning the catch
