Yup, put it to use and don't give the split a second thought. I've seen plenty of GB axes with the same, it's to be expected when using a metal wedge.
Looking forward to your impressions on this one after putting it to use. I know you had your doubts early on, but I'm still convinced it will be a good all around user.
Well I can't leave you all unsatisfied

Firstly, I decided to put a 21" handle on her. I cleaned all the rust up and sharpened her up real nice. You can tell by the picture that she had significant cheeks when I sharpened her.
Took it out back today and I split some camp type size firewood (dry) just to see how well she split, and yes as expected, she is a splitting machine. This is probably the best camp axe you can buy, its a little less than 2 lb head (I think 1.9lb when I weighed it), so it has some heft for splitting those types of pieces. Very little effort to cleanly split dry wood (not too large though as it is kind of a small axe). You can split with 1 hand easy enough, but trying to cross grain chop with 1 hand is difficult. It can be done, but I wouldn't want to do it for more than 30 seconds.
We have a fallen Spruce (I think) that got uprooted in the last windstorm we had over here on the Pacific Northwest. I've been using it to hack up, its very green so keep that in mind. I did a 3 swing chop test to see how deep she would bite. And she chucked up a decent size chunk. The high centre line really helps push out the wood.
I am just a recreational user by all means, but she is very capable. I am actually giving this to my brother in law, he goes camping quite a bit with his family, and uses his axe at camp soley for splitting camp fire wood. His current axe he says has a flexible handle

not sure what that means, but he says is flexes when he takes down strokes...sheesh. So I decided to make a little gift for him since I know he'll never replace his piece of junk axe. This is reason I was worried about the crack in the eye, but I think all will be okay.
