Gravity knives are becoming increasingly popular amongst knife enthusiasts and collectors alike. With a sleek design and innovative mechanism, these knives offer a unique and efficient way of carrying out various cutting tasks. However, with so many options available in the market, choosing the right gravity knife can be a daunting task.
In this buyers guide, we will explore what a gravity knife is, how a gravity knife works, the history of gravity knives, and so much more. Whether you're an avid collector or just looking for a reliable cutting tool, this guide will provide you with all the information you need to make an informed decision.
History of Gravity Knives

The history of gravity knives can be traced back to the late 19th century when they were invented for use by military paratroopers. These early gravity knives had a folding blade that could be easily deployed with a flick of the wrist, making them ideal for quick access in emergency situations. They were also designed to be compact and lightweight, making them easy to carry and use while jumping from an aircraft.
Over time, gravity knives became popular among various groups, including fishermen, construction workers, and hunters, as well as military personnel. As the popularity of gravity knives grew, knife-makers began to develop new designs, incorporating advanced materials and improved lock systems for increased safety and durability.

In the mid-20th century, the use of gravity knives was banned in many countries, including the United States, due to concerns about safety and the potential for illegal use. However, despite these restrictions, gravity knives remained popular among knife enthusiasts and collectors, and many manufacturers continued to produce these knives for legal markets.
In recent years, there has been a resurgence in popularity of gravity knives, as advances in technology and materials have made it possible to produce knives that are more reliable, safer, and easier to use than ever before. Today, modern gravity knives are available in a wide range of styles, materials, and designs, including high-end custom models, and are popular among knife enthusiasts, collectors, and outdoorsmen.
What is a Gravity Knife?

A gravity knife is a type of folding knife that opens using the force of gravity or momentum to propel the blade out of the handle. Unlike a traditional pocket knife, which typically has a manual mechanism, such as a thumb stud, to deploy the blade, a gravity knife relies on gravity to unlock the blade and make it ready for use.
Some gravity knives also have a locking mechanism that allows the blade to be locked in an open position, making them useful for tasks that require the blade to be held open for an extended period of time. These knives are often used by workers in industries that require a quick and easy-to-use cutting tool, such as construction or shipping.
How Does A Gravity Knife Work?
A gravity knife works by using gravity or the force of gravity to deploy its blade from the handle. The blade is typically stored inside the handle and is locked in place when not in use. To deploy the blade, the user needs to flip the knife into a certain position and then release the blade by using a button, lever, or other mechanism.
The blade then falls out of the handle and locks into place, ready for use. The blade is usually secured with a locking mechanism, which prevents it from closing on the user's fingers while in use.
To close the blade, the user simply needs to unlock the mechanism and allow the blade to retract back into the handle.
Why Is The Gravity Knife So Controversial?

The gravity knife is controversial due to its design and mechanism of operation, which allows for fast, one-handed deployment of the blade. This feature has made it popular among certain groups, such as tradespeople and military personnel, who require a quick and easy-to-use knife.
However, the same feature has also made the gravity knife a weapon of choice for criminals, leading to its ban in many countries due to concerns over public safety.
The controversy surrounding the gravity knife often centers around the difficulty in defining and regulating the weapon, as well as the debate over the rights of individuals to carry such a knife for lawful purposes.
Types Of Gravity Knives
Out-the-front (OTF) gravity knives
These knives feature a blade that slides out from the handle and locks into place when opened.
Flip-open gravity knives
These knives use a mechanism that allows the blade to be flipped out of the handle, similar to a switchblade.
Drop-point gravity knives
This type of knife features a blade that drops out of the handle when the user opens it, hence the name "drop-point."
Lever-release gravity knives
These knives have a lever or button that releases the blade from the handle when pushed.
Ball-bearing gravity knives
This type of knife uses ball bearings to allow the blade to move smoothly in and out of the handle.
Tactical gravity knives
These knives are designed for military or tactical use and often feature a serrated or partially serrated blade.
How to Clean a Gravity Knife

1) Disassemble the knife
2) Clean the blade
3) Clean the handle
4) Dry the knife
5) Reassemble the knife
Note: Always refer to the manufacturer's instructions for cleaning a gravity knife. Some knives may require special care or may not be disassembled for cleaning.
