TRIVISA UMa-04 Liner Lock Micarta Folding Knife [TVTY07MTS]

A micarta edition of Steve Cheng's bolster layout

The UMa-04 places micarta scales behind titanium bolsters in Steve Cheng's folding design. The combination separates the working grip surface from the metal structure at the pivot. A liner lock supports the open blade, and a ceramic-bearing pivot accompanies the opening disk. Its long, narrow proportions distinguish it from TRIVISA's broad-bladed folders.

Blade, handle and carrying size

• Blade: 3.63" S35VN stainless; black stonewash finish
• Handle: Black canvas micarta
• Mechanism: Linerlock
• Pocket size: 4.88" (12.4cm) closed

Materials and cutting character

S35VN is a powder-metallurgy stainless steel developed to balance wear resistance with toughness. It gives this blade a useful combination of edge life and resistance to corrosion for everyday cutting.

Micarta combines fabric or other fibers with resin. It gives the handle a layered composite surface whose appearance can develop with handling and use.

Linerlock explained

A spring section inside the handle moves behind the blade when it opens. Moving that liner aside releases the blade for folding, so the release is accessed inside the handle rather than through a separate external button.

Construction details

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