  • You are a civilian or Armed Forces supply or procurement officer or employee of the Federal Government, purchasing knives for government-related activities.
  • You are an active Armed Forces member or employee, using the knife in the line of duty.
  • You are a supply or procurement officer of the National Guard, the Air National Guard, or a militia of a State, Territory, or the District of Columbia, purchasing knives for organizational use.
  • You are a supply or procurement officer or employee of the municipal government of the District of Columbia or a government entity of any State or Territory, or any county, city, or political subdivision thereof, acquiring knives for official purposes.
  • You are a manufacturer of such knives or a legitimate dealer ordering on behalf of an eligible customer as described in paragraphs 1, 2, 3, or 4.

Smooth Button Lock

The button-lock system delivers clean, controlled action with solid lockup and confident disengagement. Every movement is deliberate, allowing the knife to respond only when you’re ready.

PEOPLE ARE ASKING

What is a Button Lock?

A button lock is a push button allowing the blade to lock in place and not move until the button is pressed again. Upon pressing the button, the lock disengages allowing for blade deployment.

Are Button Lock knives safe?

A button lock is usually considered better and stronger than a liner lock. Additionally, it does score extra safety points for never requiring you to put your hand in the blade’s path as it closes.

Why Do You Add Titanium Coating?

Our titanium coating process increases the corrosion resistance of our blades while at the same time providing the blade with a deep matte texture.

Does the blade arrive sharpened?

Yes, all Tekto knives are sharpened before they leave our facilities. However, all blades lose their edge after prolonged use and must be eventually resharpened.

My favorite folder by TEKTO

I own the Bravo and the Charlie, both are great knives. But this knife is by far my favorite. Its compact and super smooth, smoother than the Charlie in my opinion, maybe due to the lighter weight. The button lock makes this knife fidgety, I keep opening and closing it all day long. The reverse tano is unique as most of the Tekto knives are drop points. I've used the knife for about 4 weeks and Ive cut rope, opened boxes and chopped a few branches, no issues, it did it well. Its still sharp, I haven't had to sharpen it. I received this knife free in return for an honest review.

Awesome knife!

Great knife, great color. It has a smooth action and the push button lock is very fidgety. This is like my 5th Tekto. You guys keep knocking it out of the park. Thank you!

Solid

Smaller that I thought it would be but any bigger and it wouldn’t be as good on a carry. Solid construction. Light weight

My first Tekto

The quality, sharpness, and feel of the F4 Echo far exceeds its price. I will buy additional Tekto's
