Well, I sharpened my steel dagger without any smithing perk, but I could only make it (fine). I'm assuming it's like this for all weapons.
Right, I have seen it done for steel without any perks. I am hopeful it works that way on all materials without perks. That will be the extent I will use the smithing system if that is the case. Otherwise, ya, there is no way I am getting perks just to sharpen blades, hopefully this simple procedure is independent of them.
