Petrified Fish Trilobite FAQ

The Petrified Fish Trilobite pairs a stout 3.03-inch reverse tanto blade with a responsive button lock and smooth ceramic bearing action. Built as a hard-working utility folder, it balances slicing performance with a hand-filling, reassuring grip.

What steel does the Petrified Fish Trilobite use?
The Petrified Fish Trilobite features Sandvik 14C28N stainless steel ground into a reverse tanto blade profile. This Swedish steel provides high corrosion resistance, tough edge stability, and straightforward sharpening, while the full flat grind balances tip strength with slicing efficiency.
What handle options are available on the Trilobite series?
The Trilobite lineup includes textured G10 handles in colors such as Black, Khaki, and Blue, as well as a lightweight Ultem variant. Each version includes a matching backspacer and an inset stainless steel deep-carry pocket clip with flush screws for discreet pocket carry.
How does the Petrified Fish Trilobite deploy and lock?
The Trilobite opens smoothly on caged ceramic ball bearings using the flipper tab or by reverse-flicking the blade opening. Lockup is secured by a button lock mechanism, allowing effortless one-handed deployment and closure while keeping fingers clear of the cutting edge.
How does the Petrified Fish Trilobite feel in hand?
The handle offers a secure three-to-four-finger grip with enough palm-filling thickness to support firm utility cuts without flexing. A forward finger choil lets you choke up for precise control, though users with larger hands should be mindful of how close their finger rests to the sharpened heel.
Is the Petrified Fish Trilobite a good everyday carry knife?
Yes, the Trilobite is a practical, value-driven everyday carry option typically found in the $45 to $70 range depending on the handle material. Its compact overall size, durable 14C28N steel, and deep-carry clip make it well-suited for daily cardboard breakdown, utility chores, and routine work tasks.
