Dreamtech D3931 Button Lock Ti/Zirc Folding Knife

D3931 — A drop point with titanium-and-zirconium construction

The D3931 combines a drop-point blade with a handle using titanium and zirconium. Those materials occupy distinct parts of the grip, with the thumb disk providing opening purchase separately from the metal frame’s release.

Opening and lock operation

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.”

Steel and maintenance

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.

Handle construction

Titanium provides a corrosion-resistant metal structure. Anodizing and surface machining change its appearance and contact texture; they are different treatments from adding a separate grip scale or inlay.

Supplied equipment

Black synthetic zippered storage case.
