The Tekto A3 Delta is a full size automatic folding knife built around serious materials, fast operation, and a grip that feels substantial the moment you pick it up.

With a 3.60 inch titanium coated D2 steel blade, G10 and forged carbon handle, button lock, and dedicated safety switch, the A3 Delta brings together the size and strength of a larger tactical folder with the convenience of automatic deployment.

At 8.90 inches open and just under 6 ounces, this is not a miniature automatic. It is a full size Tekto built to feel solid in the hand.

Titanium Coated D2 Steel

The A3 Delta uses a 3.60 inch drop point blade made from D2 tool steel and hardened to 60 to 62 HRC.

That combination gives the blade strong edge retention and wear resistance, while the titanium coating adds another layer of protection and gives the knife its clean finished appearance.

The drop point profile provides plenty of usable cutting edge for everyday utility while keeping the blade shape versatile and familiar.

G10 and Forged Carbon Handle

The handle combines G10 and forged carbon for a durable platform with a premium look and feel.

At 5.20 inches long, the handle provides plenty of room for a confident grip. Strategic jimping and contoured surfaces add traction and help keep the knife controlled during use.

The 0.54 inch handle width keeps the profile relatively streamlined despite the larger overall dimensions.

Automatic Opening With Safety Switch

Press the button and the blade deploys automatically from the side of the handle.

The A3 Delta uses a button locking system along with a dedicated safety switch designed to help prevent unintended deployment when the knife is being carried or stored.

Simple controls and a straightforward layout keep operation intuitive.
