Temperatures reached during buffing usually shouldn't be enough to damage the temper, unless somebody really did a bad mistake, because it needs to exceed 400 something degrees Fahrenheit to wreck the temper.
Olpappy is right.

Most folks worry too much about this. It's easy to burn steel on a belt or a grinder as the friction builds so much quicker even though you'd think it would do the same on a buffer.
If you're buffing without gloves which you should be you're going to cool off the steel long before it reaches burning temperature.
And I'm the same way on the belt sander. Since I haven't actively worked in so many years my hands are soft and feel heat much quicker than they once did.
But also the years of experience in grinding machining tools by hand tell me when to stop and cool the steel.
The reason the villagers are sharper is because they haven't been buffed dull, simple as that.
I have little problem with rust either and although I use Ballistol-Lube on many of my khuks there are several that haven't had anything on them for several years and they are rust free. Those are my non-users that stay in the safe.
One of them is the curvy as forged Chainpuri blade that stays in its vegetable tanned sheath all the time. No sign of any deterioration at all.
When we got back from vacation I was very surprised to see some spots on a Last Legend blade that stays in its sheath all the time as well. I polished them out with some 600 grit and used some B-L on it and so far so good. It hangs on the bedside in the open instead of in the safe.
I suspect, but have no way of proving, that the atmosphere in the safe is more stable than the air in the rest of the house as it's not exposed to drafts.
I think Dan has a valid thought with letting khuks cool off before putting them back in their scabbards.
Either that or take care of them immediately upon arriving home by taking them out, oiling them down and letting the scabbards dry before re-sheathing.
