Piranha Amazon Automatic Knife Mirror Polished/Sculpted Green Aluminum

The Piranha Amazon Automatic Knife delivers hard-hitting performance in a sleek, lightweight package that’s built to last. At its core is a 3.25-inch mirror polished drop point blade crafted from premium 154CM stainless steel. Known for its excellent balance of edge retention, toughness, and corrosion resistance, this blade is further enhanced by weight-reducing cutouts that trim unnecessary bulk while giving the knife a modern, aggressive look. With a single push of the button, the blade snaps open with authority, locking firmly into place for confident use whenever you need it.

The handle is just as refined as the blade. Machined from 6061-T6 aircraft-grade aluminum, it sports a sculpted texture and rich green finish that provide both grip and style. The slim profile keeps it comfortable in the pocket, while details like the integrated lanyard hole and sturdy titanium pocket clip add practicality to its design. Measuring 4.62 inches closed and weighing only 2.9 ounces, the Amazon carries light but feels solid in hand—a dependable companion for everyday tasks and beyond.

Piranha Knives has long been respected for combining precision machining with American craftsmanship, and the Amazon lives up to that standard. Every detail, from the mirror polish on the blade to the strength of its automatic action, reflects a dedication to quality you can rely on. And for collectors and enthusiasts, Smoky Mountain Knife Works is the ultimate destination. Known as the world’s best online knife store, SMKW is a Tennessee landmark and the largest knife store in the world.
