So I got a new BK9 a couple days ago and took it outside to play with it. I did some light chopping of the ice on the lake so obviously it did get wet. I did wipe the blade with my glove, not especially thoroughly, but it did seem dry. Then I put it back into the sheath.

Later on that evening I noticed the edge of the blade had developed surface rust..

Needless to say, I'm somewhat perplexed. I've never seen ANYTHING develop rust that quickly. It literally only took several hours..

Is that normal for BK9?

Is this something to worry about?

For the conditions you had it in, yes that is perfectly normal. 1095cv might be a little more rust resistant than, for example, O1, but when left in a damp state it will develop light rust like any other high-carbon steel. What you have experienced is nothing out of the ordinary and certainly will not limit your use of the knife in the slightest (just use the knife and the rust goes away, simple), but if you want to have a higher chance of avoiding it in the future just store the knife in as dry a condition as possible (dry the knife thoroughly, keep the sheath wet, store the knife outside the sheath if it is wet, etc.).

edit: with the factory edge having more manufacturing-related grooves and a rougher surface in general than a resharpened edge would have, that does give more surface area for rust to form; an easy fix that would certainly deter rust formation so quickly would be to touch up the edge a bit to make it smoother. A bonus to doing that would be a greater resistance to micro-chipping as factory edges in production knives tend to be a little more brittle due to the edge heating up when sharpened at high speeds like they have in the factory setting.

i have only one thing to add to the above info. after you clean the rust away with a little 0000 steel wool or fine scotchbrite. just rub a little beeswax on the edge. veg oil works but not as good as beeswax.
 
I was going to suggest the same thing 91 did. Strop it for a few.
 
Thanks a lot guys for all the responses. I figured it was not a problem but was kind of surprised because I had done some very hard chopping on a large ice block (frozen water from a barrel) with my new Condor Warlock and Golok a few weeks prior and there was no rust on any of them. I do have some video of that, maybe I'll upload it somewhere later on. It was savage lol. Different type of steel I suppose.
 
Vasoline or Mineral Oil, depending on my intended future uses also serves as a protective coating.
