If a knife were used for cutting as many times as a beaver uses its teeth to fell trees, the knife would need to be sharpened many times.

But a beaver’s teeth are
self-sharpening.

The teeth are hard on the outer
side and soft on the inner, so when
a beaver chews on a tree, the teeth are sharpened.

The knife makers at Titan Knife noticed this, and with that thought in mind, developed a self-sharpening, corrosion-resistant fillet knife.

The Titan Knife’s blade is
titanium, a metal known for
high endurance and slow
corrosion.

Titanium doesn't rust.

One side of the blade features a tungsten carbide coating that’s harder.

The two sides, one harder and the other softer, make the blade
stay sharp longer than usual, like how a beaver's teeth self-sharpen,
the company says.

The more the knife is used, the more “aggressive” it becomes,
the company says.

A Titan Knife rarely needs to be sharpened, but a few light strokes with any common knife sharpener will sharpen it, the company says.

The fillet knife is the last anyone will need to buy, Titan Knife says.

The company will re-sharpen, re-carbide or repair the knife, so long
as the knife wasn’t abused, for as long as you own it, for the price of
U.S. postage for shipping the knife for the refurbishing.

The knives, each handmade, come in three sizes – 6-inch, 8-1/2-inch and 12-inch – and all feature a marine-grade plastic handle.

Keeping the blade sharp and corrosion-free are an angler's biggest concerns about a fillet knife, and the Titan Knife is made to do
both better than others.
