TRIVISA Corvus-03 Button Lock Tan Folding Knife [TVTY20NG14]

Hydra Design's button-operated utility folder

Hydra Design's Corvus combines a drop-point blade with a button-operated locking layout. A blade cutout and pivot-end tab give the user alternative opening purchase. The manufacturer specifies ceramic bearings, while the curved grip keeps the shape distinct from a straight utility handle. The pocket clip and lanyard opening are separate carrying options.

Blade, handle and carrying size

• Blade: 3.13" 14C28N Sandvik stainless; stonewash finish
• Handle: Tan G10
• Mechanism: Button Lock
• Pocket size: 4.13" (10.49cm) closed

Materials and cutting character

14C28N is a stainless knife steel developed around edge stability, corrosion resistance and straightforward resharpening. It is a practical choice for a knife that sees regular cutting and routine touch-ups.

The drop-point profile combines a curved cutting belly with a lowered tip, giving it a versatile outline for slicing and controlled point work.

G10 is a fiberglass-and-resin composite. Its layered construction gives the scales a durable structure, while the actual machining and surface texture determine how the grip feels in hand.

Button Lock explained

The external button releases the blade lock for closing. The button is a lock control; the opening method remains the one shown for this model, rather than being defined by the word “button.”

Construction details

• Bearing pivot: Ceramic bearings support blade rotation around the pivot, adding a rolling interface to the opening action.
