not straight as when you look into the eye as pictured above, or not straight as in the bit doesnt line up with the handle, or a combination of both?
Here if I am seeing that correctly the head does look slightly cockeyed in relation to the handle. So now is it the head, or the handle?
Does the head have any beat marks on the outside of the middle of it? Sometimes old timers, when the head would get loose, instead of taking the time to fix the problem, would beat down on the axe head to make the eye thinner overall. This of course when you do manage to get the handle out can produce all kinds of issues when it comes to re-hanging.
