Hot Bluing O1

Basically I will be making some knives (under the knives act 1997 they will not be tactical in any way) but I want them hot blued. One will be a 10" bladed hollow ground kukri and the other is about 5 1/2" utility knife. I am thinking that I want about 58/59 Rc for the big one and 60/61 for the little one, that doesn't have to be that exact. Basically does anyone know how I would be able to get these results. If I blue the blades (saltpetre and lye) I will lose a few Rc points so could I use that as a tempering cycle. The blades will be 5mm and 3mm O1. I will most likely be using charcoal so I won't really be able to know exact temperatures either. Funds are limited to I'm still at school kind of money. Any advice is helpfull. Thanks guys.
