I'm new to the world of restoration so would appreciate a little help. I understand pitting and what it looks like and also understand that you should try and remove as much as possible without compromising the blade.
On the blade I'm working on which is a cheap vintage off eBay to practice on so any mistakes don't really matter as it's one to learn on and if it all works fine.
Now the question, what are the black marks on the blade and do I have to sand these out completely with a low grit before moving up the grit scale. I understand the progression to get the desired finish but you can still see these black marks, which look like a water drop has splattered on the blade for want of a better description.
Once I've got the answer to this question another one has popped into my head, how do you know when to move to the next grit?
Thanks again for your time, it's appreciated.
Apologises if I've missed this somewhere on here but there are so many threads to look through.
