Heretic Knives

The Hydra V4 is a single-action OTF (out the front) automatic knife and was the first of its kind to feature a button safety and double-prong pocket clip. This clip design has since been updated though as the double prongs created double the snag opportunities. So, this one is much more pocket-friendly. To operate the knife, simply move the button safety over with your thumb, then press the button underneath to fire. In order to retract the blade, press the button while pulling the charging handle from the bottom of the knife. Release the button and return the charging handle to its original resting state. This recharges the spring inside and resets the mechanism, ready for another impressive actuation. This is one of the few single-action OTF knives still available and was proudly made in the USA.
