I've been shaving with the Mach 3 while my three straights were off to be honed. Unfortunately it's been great. Blaspheme!

In many ways I still prefer to shave with the straights but the disposable blades are so sharp I can shave 8 ways on my face with no irritation.

Can straights be honed to near Mach 3 edges? Would an edge like that require a lot of up keep? I haven't tried my hand at honing but I cold see myself becoming frustrated trying to achieve an edge like that.
