Nothing gives man a dopamine rush like a combat knife hunt. There's a blood bond between the two - the tool and the maker - their history goes back millions of years. It was a moment of genius when man realized a sharpened stone could give him an unprecedented advantage over his enemies and nature - help him hunt faster, gather food, and make shelter. The invention of a combat tool was a turning point and one that would shape human history and evolve into combat knives.\nWhat Are Combat Knives?\nFirst, let's quickly clear the confusion around the term - “combat knife.” While it’s loosely used by sellers, it’s not accurate or ethical to describe any tactical knife or switchblade knife as a combat knife. These days you can find kitchen knives and pen knives on Amazon that are labeled as 'combat knives'. That's misleading. So, let's clear up all confusions surrounding these bad boys and take a stab at the best, yet little-known ones. So, what is a combat knife? A combat knife is not any switchblade knife. Historically, it’s been a fighting knife that's designed and engineered for hand-to-hand or close combat fighting. However, trench warfare transformed the role of the modern combat knife. The knife was reimagined to become more versatile for survival purposes - cutting foliage, chopping wood and branches, opening food tins and supply crates, etc. On top of their original role as close-quarter combat weapons, they are now also referred to as 'fighting utility or 'combat-survival' knives.\nX Little Known Hi-Performance Combat Knives\nSome feel that the humble knife has no place in the age of push-button precision weaponry.
