Tekto Knives A3 Delta

The Tekto Knives A3 Delta is a folding automatic knife that combines the consistency of a folder and the speed of an OTF. This knife offers elegance and durability in a reliable and consistent form factor. Sacrifice nothing, be ready for anything.


Positioned at the rear, a crimson red indicator signals the knife’s readiness to strike, while a forward shift activates the lock, reinforcing its steadfast closure and effectively deterring any unauthorized attempts to open it.


Strategically positioned jimping on the handle, combined with expertly contoured contours, create an unparalleled grip that not only fills the hand perfectly but also guarantees exceptional comfort in various hand positions, ensuring an unrivaled tactile experience.


Offers an enhanced thumb position, improved control, and versatile hand positioning with enhanced functionality, maneuverability, and tactical precision with or without gloves.

Chosen by our team because we value functionality and liberty.
The A3 Delta is a wicked combination of speed, agility, durability, and functionality. It features an automatic open feature for speed and consistency. The folding form factor will be second nature to anyone who has used a folder previously. This is a more traditional take on an automatic knife. Keep in mind: Automatic knife laws (unconstitutional decrees) still apply. For this reason, we ONLY ship this knife to Pennsylvania residents at this time.
