For US grenades, it is pretty much fantasy. Can it been done? It is possible, but would most likely damage your teeth. This myth has been tested before a few times. They have tested the force to pull a factory set pin on US grenades, it was surprisingly a lot of force, more than what most people could do without damaging their teeth. This isn't and has never been taught in the US military. But, other countries grenades can be more force (harder) or less (easier) to pull the fuze pin/ignitor wire depending on the model. So is it possible? Yes, depending on the grenade model and the person, but would likely result in damaged teeth. 

I would like some help identifying this long percussion rifle that I have been offered.  What I have learned is that it is Prussian produced by Saarn. Im not sure of the model - 1809? 1834? Im not sure - there is a number on butt looks like 1836 but im not sure if that is a date.   i have read that both the Union and the Confederacy imported this type of Potsdam musket at start of war -  does this look like it could be a civil war issued rifle and does it look original? The muzzle looks to have been cut down - im not sure if this was done upon issue or once returned to civilian use.   how does its condition affect the value.   Thank you for any comment/advice for verification and purchase.

Not taught in training, and not possible.     Hollywood contrivance.     It takes a fair amount of force to pull the pin on a grenade.  

Has anyone here ever tried to pull a handgrenade pin with your teeth? I’ve seen it done in movies and just saw it on a piece of art. But I’m a bit skeptical about real life. Is it even something taught in Grenade training? How big were the dental bills?  Thanks!  mikie

Thanks Kurt.  I'm glad you enjoyed them.  I have more but that's all I have pics of at the moment.

Fleet Logistics Support Squadron 52

Here's a really cool piece I picked up a while back. A Japanese Arisaka bayonet captured and modified into a fighting knife by Cpl Clifton Walter Gonce in WW2. Cpl Gonce served as a Field Artillery Crewman (603), the WW2 equivalent of our modernday 0811 Canonneer, with George Battery 3rd Battalion 11th Marines (G/3/11) and Headquarters & Service Battery 5th Battalion 11th Marines (H&S/5/11). Cpl Gonce embodied the saying "Marine Canonneers are a jack of all trades" being qualified in multiple military specialties: FldArtyMech (913), AutoEquipOpr (929), and Dispatcher, motor vehicle (410). Cpl Gonce fought with G/3/11 during the Battle Of Guadalcanal and with H&S/5/11 during the Battle Of Cape Gloucester. While fighting on Cape Gloucester Cpl Gonce was awarded the Navy and Marine Corps Medal, the highest non-combat decoration awarded for heroism by the Navy and Marine Corps, for cutting his way into a wrecked plane and rescuing the injured and deceased aircrewmen then transporting them to a field hospital. Cpl Gonce was discharged from the Marine Corps in September 1945 and moved back to his hometown of Baltimore Maryland where he served and retired as a Patrolman and Detective from the Baltimore City Police Department. He enjoyed fishing and crabbing which is what I believe he used this fighting knife for, as it looks to have seen several years of use and the holster it came with appears to be a civilian KABAR fillet knife sheath. He passed away June 16th, 2020 and was laid to rest in his hometown of Baltimore, Maryland. A full write up of his Marine Corps service can be read on my instagram post about this piece if interested: https://www.instagram.com/p/DW9r_rNEVvG/?igsh=cjdyeXdvZjh4dTh4

What unit is this for, not a ship I should think, maybe some kind of Shore Unit, tab from the 60s-70s I think.
