It’s looking good Mate and the pitting is not going to matter a great deal, after all it’s an axe not a fine wood chisel Also as you keep using and sharpening it, it will get better with time And you can guarantee if you get an axe sharpened and polished to a perfect edge you will find a knot or stone the very first time you take it out
With the 'perma bond' and the round wedge I'm guessing it's a Swedish Axe
That is an excellent freebie if it is Swedish. Only better deal would be if you had gotten some Swedish meatball ladies to go along with it
