  • A5 Spry

    “My first Tekto knife and it won't be my last! Great quality. Solid feel and lock up after deployment! Easy to operate thumb control. Great finish on scales and blade. Came shaving sharp! Many thanks!”

    Adam W.Verified Buyer

  • A3 Delta

    “I manage 4 acres of land. My last folding knife picked up some grit with daily use. This A3 delta is tough, smooth, razor sharp and has already taken a beating.”

How It Opens

Out the Front or Out the Side

Every TEKTO® automatic opens with one press of a button. The difference is the path the blade takes.

The Blade Slides Straight Out

Push the button forward and the blade comes straight out the front of the handle. Pull it back and the blade goes in. Every TEKTO OTF is double action, the handle is the same size open or closed, and your fingers never touch the blade to close it. Shop all OTF knives.

Swings Open Like a Pocket Knife

Press the button and the blade swings out from the side, with a full-size grip once it is open. A safety switch locks the blade shut in your pocket.

Blade Steel

Working Steel or Premium Steel

Buying Guide

How to Choose

Four questions narrow the lineup to the automatic that fits your day.

  1. Pocket Size or Full Size?

    The A2 Badger and A5 Spry Mini carry a 1.85-inch blade and weigh just over 2 ounces, an easy carry for boxes, cord and small jobs. The A3 Delta Mini brings the side-opening design down to a 1.90-inch blade. The A5 Spry, A7 Zastava and A3 Delta carry 3.50 to 3.60 inch blades and fill the hand for bigger cutting.

  2. Which Blade Shape?

    A drop point is the best all-round choice for everyday cutting. A tanto has a strong, angled tip for tougher work. A double edge is sharpened on both sides for precise cuts, and the spear point on the A7 Zastava balances strength and control.

  3. Plain Edge or Serrated?

    A plain edge makes clean slicing cuts and is the easiest to sharpen. Serrations saw through rope, cord and webbing. The A3 Delta comes either way, and the A4 has a serrated double edge.

  4. Which Handle?

    Aluminum on the A5 Spry series and A4 is light and smooth in the pocket. G10 on the A3 Delta and A3 Delta Mini adds texture for a sure grip. The A2 Badger also comes in carbon fiber, and the A7 Zastava comes in American Walnut.

FAQ

Questions Before You Buy

See All FAQs

How Do OTS and OTF Knives Differ?

An automatic OTS knife folds in on the side and has a mechanism that opens the blade automatically with a button or switch. An automatic OTF knife also opens with a button or switch, but the blade extends straight out the front of the handle.

Are TEKTO OTF Knives Single or Double Action?

Double action. Push the button forward to open the blade and pull it back to close it. You never touch the blade to close the knife.

Are Automatic and OTF Knives Legal Where I Live?

It depends on your state, and sometimes your city or county. Some places allow automatic and OTF knives with few limits, while others restrict blade length or where you can carry one. Our Knife Laws by State guide breaks down the rules in all 50 states. In California, state law allows automatic knives with blades under 2 inches, such as the A2 Badger, A3 Delta Mini and A5 Spry Mini.

How Do I Reset My Automatic Knife?

TEKTO automatic knives have a built-in safety mechanism that lets the blade go slack in the handle if something blocks its path as it opens. If your blade feels loose, follow the steps in our OTF reset guide.

Can I Take My Automatic Knife Apart?

Please don’t. Most issues clear up with a thorough cleaning, and our OTF cleaning guide walks you through it. If something still needs attention, email us at support@tektoknives.com and we will take care of it.

Are TEKTO Automatic Knives Left-Handed?

Several are. For left-handed carry we recommend the A5 Spry series, the A2 Badger, or the A3 Delta, which has a reversible belt clip.

Is Every Knife Here Covered by the Lifetime Warranty?

Yes. Every genuine TEKTO knife is covered against defects in materials and workmanship for the life of the knife. The warranty stays with the knife when it is passed on, and you never need a receipt. See how the Lifetime Warranty works.
