Viper Tec OTF Knives & Automatic Pocket Knives

Find your next everyday carry at Viper Tec. Explore out-the-front knives, side-opening automatics, and compact pocket models in a range of sizes and blade styles. Compare options that fit your preferred carry size and budget.

Shop our full selection of OTF knives to compare models, blade configurations, and current availability.

Find Your Preferred Knife Style

Our double-action automatic OTF models deploy and retract with a thumb slide. Explore the Ghost Series OTF knives to compare blade styles, colors, and sizes. Available configurations vary by model.

Prefer a blade that opens from the side of the handle? Browse our switchblade knives and compare automatic pocket knife designs. Check each product’s specifications to confirm its opening mechanism, dimensions, and available options.

Compare the Details Before You Choose

The right pocket knife depends on more than its appearance. Compare blade steel, cutting-edge shape, handle dimensions, and weight against the tasks you perform most often. Compact models take up less pocket space, while full-size designs offer a larger grip and longer blade.

Use each product page to review specifications and photos, then check the warranty, care information, and shipping terms before ordering. Whether you are choosing your first automatic knife or adding another model to your collection, start with the features that matter most to you.
