It's not a good or bad thing, it's a surface condition. Normalising is most likely what did it. Extended exposure to heat creates lots of scale and some times it forums in little round blister shapes. There is also a layer on the surface called decarb that has had the carbon burned out of it. This is why we normally grind or sand after heat treat. If you don't have a grinder then use a corse grit paper and start sanding till all the scale scaring and decarb is gone then move up in grit and finish the blade. But like I said as long as the heat treat was done right and everything is spot on then it's just a finish issue and not a structural problem.
If it's a simple carbon steel you can just give it a dunk in some ferric chloride. Steel with real low carbon content will etch much lighter color then the hardened steel.
Just finished it. Plan on abusing it tomorrow to see if it holds up. We will see. I am still figuring it all out. This is knife #4 i am not to worried about the mirror finish yet, until I get the basics down.
I do. It is not a great picture. The bevel near the tip needs corrected. I will work on that tomorrow. I made a jig to help hold my angles. I am not real good at it yet. But I will keep practicing.
