Why are slat and glass and other calls of this type call round and not square ?

Does round sound better or does it have to do
with a square call cracking ?

Thank You

JR,Not all of these calls are round.I have some that are square and some that are rectangular and they sound just fine.I don't know thy most are round.It might have somethin to do with the fact alot of people make yelps on this kinda call usin a circular motion.But I really don't know .Good question.

It might be because the first slate calls were probably just a round piece of slate held in the hand, with no sounding chamber attached...The index finger and thumb would encircle the stone and the other fingers closed against your body to form the sounding chamber... At the first turkey seminar I ever attended, Dave Streb used several stones this way and made some good soft calls with them... That's just a guess on my part...As jalvja said, some slate calls are square or rectangular and probably other shapes too.. One famous example is the Lynch JET slate, which was a small rectangular slate call and was one of the few slate calls on the market in the 1960s when I started turkey hunting..

I agree with Pygmy and Jal as well. But since I work with wood, I think it's just easier to make them round than square.

Id say that its because a round call is easier to hold and feels more comfortable than a square one, but Im not sure.

It keep the mice in my house from chewing the corners.

LOL!!!! Good one C120!!!

im not sure

I dont know, but a square call doesnt seem like it would be very comfortable in my hand.

I think they are round so that when guys like me get irritated at a bird they throw the call and then it rolls down the hill like a run-a-way tire...................they you have to buy a new one because the one you threw rolled into the creek or down a groundhog hole....
