The hard way, for several reasons
I understand the costs add up when you're learning, but I sure wouldn't want to try learning restoration and honing at the same time. I wouldn't try resto w/ a 4k if I were well paid. 'Would be nice to be able to get the 'feel' of the blade and the stone when things are as they should be, then tackle the blades that need restorative grinding. You're on a hard path, my friend. Any member near you that would help w/ either some tutorial time or have some lower grit stones they'd let you use? 'Would save alot of work & frustration. Good Luck.
