Nah.....better read up on that before making opinion based statements and making them sound as if they're factual.
OK you got me.... oh well it was late and I swapped boar with hog... Boars run wild and hogs usually refer to LARGE pigs... However pig is usually used to refer to the domesticated version. If you want to split hairs boars can also refer to uncircumcised male pigs... As a non pig breeder all I can do is try and remember these things from readings but you may interject anything you may know from experience...
As far as it having higher elasticity than cow or buffalo... That one I will just have to stick to... That one comes from testing different leathers and tips over the past 4-5 years... Japan has developed it's own breeds of pig and in general they have a tighter hair follicle pattern which makes for a tighter grain. I wish I could source that but that was what I discovered several years ago comparing different leather samples and talking to leather experts in trying to understand why it was Japanese Pig Skin that seemed to make the best tips.
With there being 100s of breeds world wide some breeds from other parts of the word may have the same characteristic or even better ones... I have no need or desire to check on that as all I care about is COR and Springrate vs Hardness in any material that goes on the end of a cue mainly the Original Mooris interest me the most.. I do with chemicals what mother nature did not do as far as modifying those aspects of traditional cow and buffalo to give those hides higher elasticity than they normally have from a tanner....
