TRIVISA UMa-05 Liner Lock Carbon Fiber Folding Knife [TVTY07CTS]

Steve Cheng's bolster-and-scale design

The UMa-05 combines carbon-fiber scales with titanium bolsters, giving the grip a distinct division of materials at the pivot. Steve Cheng's design uses a liner lock, ceramic-bearing pivot and an opening disk on the blade. Its longer folded format and narrow blade outline create a different proportion from TRIVISA's compact crossbar models.

Blade, handle and carrying size

• Blade: 3.63" S35VN stainless; stonewash finish
• Handle: Carbon fiber
• 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.

Carbon fiber combines reinforcing fibers with resin, adding a visible layered or patterned character to the grip. The selected weave or inlay is part of this version’s appearance.

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.
