Doesn't matter, as long as they end in "i". Which still leaves you lots of choices: Thurri's, Coti's, Nani's, JNati's, Norti's... Just keep in mind that you'll never acquire true Honesheister status unless you (a) blend in with the Pro's (ie, forget grammar - especially correct plurals) and (b) gloss over blatant lack of experience with ghetto slang and lower class manners.
I have the distinct feeling that anyone looking for a quick buck from straight razors has less interest in ladies than in ... ah well, let's not go there...
Seriously, and in a nutshell: There is a limited number of people to whom I would entrust any of my razors. All of these people have several years of experience, and have honed thousands of razors - on all types of abrasive media. I am at a complete loss as to why anyone would want to charge for honing unless he has the proven ability to match the quality (read: consistent success rate across all types of razors) of these people's work.
