Which country produces the most IRON jaws?

Mexico...hands down. Big headed asses.

 

Mexico but maybe this thread can make me change my opinion. Mexican fighters are normally at the lower weights where one punch knock outs are not as common

 

Mozambique

 

They are two times soccers world champions

 

1.Mexico
2.Argentina

US has produced good chins, but it shouldn't really count since there's such a disparity in races, cultures, ethnicity s, etc. It should be divided by states/regions to make it a little clearer. Cause Brooklyn definetely has a concentration in glass hearts.

 

And the best South American Rugby Team.....

 

Because you ***s are the easiest to 1 punch KO.

 

Rugby is nothing in South America so that means nothing

 

Still they are good and they have good basketball team also. But anyway it was not the idea of the thread.

 

Yes they are good. They can give the world's best problems

 

Mexico, but if the American Midwest was an option, I would have picked that.

 

That's true if you consider Penelosa, Manny, Donaire they are extremely tough

 

here is the thread related to british jaws:

Mexico. A Glass Jawed Mexican like Canelo is an utter rarity in Mexican pugilism.

 

Some Italian fighters had some of the best chins/jaws ever... Jake LaMotta, Carmen Basilio, Rocky Marciano, Toni Canzoneri, Joey Jardiello, Vito Antuofermo, Arturo Gatti, Duilio Loi, Sammy Angott, Joey Maxim.
