Summary: What Is A Gravity Knife
A gravity knife is a little tool with a blade folded in the handle, which is released because of hand motion as well as a gravitational force. The main idea of its construction is to support releasing the folded blade with simply one hand. So, when the other hand is unavailable, it is simple to open this knife with just a wrist flip.

History of The Gravity Knives
History of The Gravity Knives
The gravity knife was mainly designed to support soldiers and crew members of aircraft in releasing themselves from their parachutes that got twisted in objects such as trees at the time of landing. Hence, it was created in such a form that just one hand could open as well as use it.
Founded in Germany, these knives were introduced during World War II. While the war, the German soldiers would get confused at times in their parachutes. Nearly all knives of that time required two hands to open. This tool built it tough to use these knives in this situation.
Moreover, the chance of being caught by the allied forces was always there before becoming free from the difficulty. So, a knife that could open with just hand was introduced.
Later, the allied officers who took them from the German culprits returned to the United Kingdom and the United States. They termed these knives as gravity knives, as they applied gravity to open. A gravity knife was designed before the discovery of an affordable and safe switchblade knife.
It is created by the German air force, the first gravity knife came in 1937. It was called the Luftwaffe Fallschirmjäger-Messer.
Gravity Knives Types
In terms of how the blade opens, there are two types of gravity knives, which are as follows:
- Standard: It looks like a folding knife with one of the sides owning a hinge. For opening such a gravity knife, it serves to press the lever on the side and flip the wrist in a rear-handed way. This lever adjusts the blade and stops it from turning loosely on the hinge. The flick’s inactivity brings out the full blade while freeing the lever holds the blade in its open position.
- Out the Front (OTF): This is the form in which the blade switches in the hilt. It is built to glide out straight. This time, the lever is over the front of the corner atop the handle. You just lack to pull the lever to turn the handle forward, take the hand back, and glide the blade forward where the lever locks it.
There are some further varieties to examine. Once the German gravity knife became popular, its British version was soon introduced in England. This knife was built to operate as a secondary combat weapon.
It was pretty like the German knives. Though, there is a variation in terms of handles, which can be of smooth wooden or plastic.
Even a butterfly knife is thought to be a gravity knife. Yet, there is a variation. This knife depends on the actions of your hand, not on the gravitational force.
Moreover, in the case of this pocket tool, the handle has two parts that you can flick just like the butterfly’s wings. You necessitate moving the two parts away from opening the handle.
One excellent example of a modern-day gravity knife is Paragon Warlock.

The Opening and Closing Of Gravity Knives
A gravity knife operates by relying on inactivity and the gravitational force to release its folded blade. When it was created, the idea of spring-driven knives was not very popular. Hence, there was no chance of the spring mechanism to be involved in it.
While a fixed combat knife can be opened with one hand, it is large and is expected to get departed from its case at the time of parachute landing. Though, a gravity knife is short enough to implement carefully inside a pocket with a zipper.
The blade simply falls open when the knife leads towards the ground. When not in use, a lever holds the blade intact in its position by locking it. Once the blade is out, you can flip it back to prevent accidental falls at bay. This is how a gravity knife is between the easiest knives to open, carry, and use.
Even today, a gravity knife’s blade with a blunt-spear point remains folded in a frame built of metal. This case is inside a wood handle. As you flip the lever residing on a side, the blade stretches out from the frame and opens completely because of the force of gravity.
Closing the blade is similarly a breeze. Just flipping the switch again, which appears in freeing the blade’s lock. By flipping the hand in the frontward motion, the blade becomes unfold, while otherwise, the switch is released to protect the blade in the frame.
As contrasted to a standard folding knife, a gravity knife is nearly alluring. This is because you can open and use it with just one hand. The recent knife’s closing mechanism is normally too hard to be flicked with just one hand.
Gravity And Other Knives Similarities
Gravity And Other Knives Similarities
The Switchblades and gravity knives are frequently mutually used, as they both are much alike. Some people consider a gravity knife to be a switchblade kind. Though, they both are distinct.
The principal exception is how they both work. Both knives indeed have their blades embedded inside their handles. Nonetheless, the opening tools each of them follows is changed.
The Gravity knives employ a locking lever and lead to open because of gravity after moving the level. On the opposite, switchblades or OTF knives work with the guidance of spring being in the handle. Pushing a button automatically frees the blade. So, unlike gravity knives, switchblades are automatic.
Many latest folding knives appear with a pin close to the folded blade’s side. You lack to flick this pin to open the knife with just one hand. This suggests they are identical to gravity knives in terms of functionality. Nonetheless, unlike gravity knives, these knives come with strong hinges. In other words, a user of a gravity knife can more instantly draw and open the knife than a user of a folding knife holding a pin.
Utilization of Gravity Knives
In its first days, the gravity knives were used to support soldiers while alighting or falling from airplanes to evade being caught in a difficult situation. Although they were not created as fighting knives, gravity knives were also used for battles
These knives were additionally accessible with various attachments such as an awl or marlinespike. The marlinespike is normally used in marine ropework and is identified to untangle knots. Likewise, the awl is beneficial for prying open, piercing, and fixing blocked weapons. All these addons folded into the knife.
The legality of Gravity Knives
The concern with the legality of gravity knives has been the description of the knife, which can differ from country to country. Though, in the bulk of states, a gravity knife is legal. In other states – such as New York till the change this year – administrators had put gravity knives in the identical category as a switchblade, which opens into a locked position with the push of a button.
The gravity knives are intended to open with gravity or a flick of the wrist so that they can be opened one-handed while the other hand is occupied. That is why the knife is very famous as a tool for tradespeople.
Repeat, commonsense has not been eternally controlled when it occurs to laws governing these knives. Some countries outlaw gravity knives, including the United Kingdom and Canada.
Other countries are contemplating laws to lift the ban on gravity knives, including Ohio. Other states are considering legislation that involves lifting bans on some type of “automatic knives,” which in some states can include gravity knives.
Conclusion
The gravity knives are created to be opened with just one hand because of which they are famous amongst people involved in a trade or normal chores needing knives. Although they are now certified in New York, they are yet banned in other American states. Therefore, it is wise to check the laws and then purchase, carry, or use gravity knives.
