When I see a flint for sale and it reads 5/8" x 3/4" my way of thinking is, 5/8 wide X 3/4 length. Is this a correct assumption or what is industry standards ?, can they be any thing the seller wants them to be. The reason I ask is it seems lately that flints I have ordered have some very sketchy measurements from advertised. I realize things are tight but when I order 5/8 x 3/4 I do not like getting 1/2 x 1/2. I always try to buy locally so I can visually see what I am getting but locally is getting tough for good flints.
