A very good question which I will address.
Can I address the question in a more concise manner. Will the knife rust ? The answer is YES. 01 is a great steel for bushcrafting but not for stalking IMHO.
A very good question which I will address. 01 carbon blades are an extremely tough blade which hold an edge well.
It is true that 01 carbon steel, due to its make up, will indeed rust if neglected. As stalkers, we all will religiously wipe blood and water off our rifles as we all know it can lead to rusting of the barrel. Some people forget their hardworking knife and sling it into the bottom of their bag, to be washed at a later date. Personally, I feel this is a bad habit and if we were truthful, poor practice. All that needs to be done to prevent a 01 carbon blade from rusting is to rinse under the tap and dry. If the knife won't be used for a while, then a light coating of oil would be recommended.
It should be remembered that some of the finest blades are made from height carbon steel such as cut throat razors and even samurai swords which all must be treated with care. You will also see modern knives such as rays mears is also made from 01 carbon.
About the patina, the 01 carbon steel will,over time develop a natural patina though this in itself will not prevent rusting. There are other solutions such as making knives from stainless steel but the cheaper stainless steels tend to roll on the edge when in use.
I can purchase high grade stainless steel blanks but the cost is roughly double of 01 carbon
The answer to the question you asked is there and I guess I will have to bow to your superior wisdom regarding knife making, plus all the stalkers who choose to use 01 , Damascus , Opininel and the non stainless version of the classic Mora knife will to, for they are have a high Carbon content and rust also.Like I said, a bad worker blames his tools for none of the knives mentioned will ever rust on their own. As regards to bushcrafting, I know alot of bushcrafters who use 01 and boy do those guys abuse their knives and parangs ect. they never have problems with rust and I seem to recall Ray Mears using his 01 knife to gralloch and cut up deer during his series....oh and hes a stalker too.
