TRIVISA Firefly Ultra Crossbar Lock Ti Folding Knife [TVYD04SM]

A titanium crossbar model with a compact blade

The Firefly Ultra pairs a compact swedged blade with a titanium handle and crossbar lock. TRIVISA's in-house design keeps thumb studs as the opening interface, with ceramic bearings supporting the pivot. Its relatively narrow blade and short folded length make it distinct from the broad working profiles elsewhere in the range.

Blade, handle and carrying size

• Blade: 3.00" Bohler M390 stainless; stonewash finish
• Handle: Gray titanium
• Mechanism: Crossbar Lock
• Pocket size: 3.75" (9.53cm) closed

Materials and cutting character

M390 is a powder-metallurgy stainless steel with high wear resistance and good corrosion resistance. Its appeal is an edge that resists abrasive wear during repeated cutting; regular light maintenance helps avoid a more demanding full resharpening.

The reverse-tanto profile angles the spine down toward the point while retaining a useful cutting edge beneath it. The result is a distinct tip geometry for controlled utility work.

Titanium gives the handle a corrosion-resistant metal structure. The color and surface treatment describe its finish; they do not change the underlying handle metal.

Crossbar Lock explained

A transverse bar engages the blade to hold it open. Pulling the bar back releases the blade for folding; the release sits near the pivot rather than along the cutting-edge channel.

Construction details

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