Is it possible to pull grenades with teeth like in movies?

Maybe many of us have been fooled by the details of using teeth and pulling out the safety grenades in action movies. But in fact, is that possible?

Grenades are one of the most important weapons in every war. So far, grenades are still in use and constantly improved to increase the damage.

The composition of a grenade consists of a metal shell, an empty intestine and a gunpowder inside. According to Wikipedia, when pinning the safety tail of a metal fire on the speculum head, the fire-spring needle burst into the fire particle. The fire particles burned the slow-burning medicine, then fired fire into the grenade's detonator.

Besides being a pure damage weapon, grenades also symbolize the quick wits and clever handling skills of soldiers in combat.

The withdrawal of a grenade will require quite a bit of arm force to pull the key.

But when it comes to movies, some special details are the use of grenades, which are overly exaggerated by directors and filmmakers. In many films, you may have seen a few scenes of grenades pulling out with teeth and throwing them at the enemy. But it turns out, that's not entirely true.

First of all, understand that grenade's damage range is quite small and you need to use a lot of force to throw it away. In a grenade, there were not too many explosives. That means that this weapon can only destroy the enemy in close proximity. Also, you cannot throw grenades too close or too high. Because the target will have the opportunity to throw it back to your location.

It is then necessary to understand that the grenade's safety pin is often extended. This helps the safety latch will not be easily withdrawn accidentally or fall out.While fighting, the withdrawal of a grenade would require quite a bit of arm power to pull the key.

Of course, grenades are designed to ensure that every soldier from normal to athletic can easily pull out without too much trouble. It is estimated that an American M67 grenade will need at least 3-5kg of force to remove the pin. A level of force is not too difficult but it is not easy to use teeth , unless the person has a very strong jaw and is a practitioner of qigong.

In particular, Russia's grenades are even more difficult to pull off with teeth. Later, there were many types of grenades with a more complex draw mechanism such as Singapore's SFG87 that had to be twisted before it was finalized. Therefore, the withdrawal of the key is not as simple as the movie. On top of that, if the hands were still healthy, hand grenade safety was still the most effective in combat.
