A long time ago, I thought about checkering. It seemed to me that this was supposed to make a more solid control of a gun. Then I moved to these very cold mountains where it was not possible to go hunting in the winter without heavy gloves.
The thought that checkering was not very important in controlling a gun seemed to be rational.Extending this thinking led me to think that it was mostly decoration.
Then I thought some more about this.
The checkering certainly did not denigrate the control when clothed as Nanuk. But, the sharpness of said checkering did seen to have a purpose.
Northern America is far colder than Europe. More protection is necessary here than there. Sharper pointed checkering is sensible.
It seems plausible that pointed checkering evolved here when flat checkering was the norm elsewhere.
Does this make sense to you?
Best,
John
