"need" is a bad word that needlessly confuses things more often than not. You also don't "need" hones if you have the appropriate pastes- they both work.

I have not noticed a need to hone a blade often that was stropped properly. As we know, honing cuts the blade, too much or too often will shorten the life of a blade.
Well, not at first. What I'm suggesting is that if you use pasted balsa, for example, instead of bare leather every day, you shouldn't have to go to the hone for a real long time, and you'll always have 'fresh' edges.

I personally think the use of pastes for honing at anything other than a very fine polishing stage is a relatively new phenomena.
I'm not talking about replacing coarse hones with coarse pastes, just more frequent touch ups so that you don't have to go so coarse.

I maintain my knives with a pasted strop, and only have to go back to stones if I get so much use in one session that it dulls them past what a strop can quickly fix.
