The wedge type grinds, have way more steel that can be sanded away, without harm to its integrity.
So when I say "many O' hours". Were talking days, in collective hours. It all depends on the grind, and how far I can go, with the damage at hand. ( learned thru trial and error )
Besides the shave, that's why I prefer the heavy grinds. They're the ones, if not honed to death, that are worth the time making look new, again. There's just not a lot you can do with full hollows, with a bunch of pitting.
Just clean them up the best ya can, hone and enjoy them. The more you do/restore, the more you'll learn about their limitations, and your own.
All the information you need, is right at your finger tips, and found in this forums library, and work shop. From there its learning a skill, set. Or I should say, learning the unknown.
Like anything.... You only get better at it, the more ya do it. The more you do, the more it becomes an instinct. That's why I like project blades that give me a challenge, it pushes me to a higher skill set, or level of learning out of my comfort range.
But I'm that way with anything, that I put my mind to. I just gotta know what's behind the next, door. Always forward, never stepping back.
