I have searched about INFI rusting, and from what I found it seems to be pretty decent as far as corrosion resistance goes. I was just wondering, does anybody mind if they are out on a camping trip or something for a couple weeks and they have to constantly care for their super expensive knife blade because if they don't it will likely develop rust? Personally, I find it hard to get past the fact that a knife that expensive, designed for hard use in combat environments could rust on you if you don't constantly wipe it off and oil it. I doubt any military would even think of issuing a rust-prone knife to soldiers in the field who need dependable equipment. I can clearly see that Busse knives are super good because so many people praise them, but they RUST! Doesn't that bother you? Are they ideal for combat environments other than the bone dry desert? I saw some pics of a Battle Mistress with a ton of rust all along the edge where the black coating flaked off. Would a soldier appreciate that? I am not saying they aren't really great knives, but they do require regular maintenance right? Even to store them for any length of time, don't you have to coat them in some kind of WAX or something so they won't rust? They look really awesome, but why must must they rust
I like to think of myself as a swordsman. That is to say, I collect and practice with swords - and not wall-flower, stainless steel decorative swords, but blades designed for combat use, both modern and old. These are all carbon steel items, highly prone to rust under certain circumstances. Yet these are also the kind of items soldiers used, in the field, for many centuries. And they rust, and a lot, if not properly cared for.
Yes, it does bother me that blades rust. Things would be somewhat easier if they did not. But it doesn't bother me so much that I'd wish to avoid carbon steel blades, especially not when stainless steel rusts quite readily, as well, in the right (or should I say wrong) conditions.
INFI does not require "constant care", though, and neither do any other decent steels I know of. All the maintenance I can typically be bothered to do in the field is wiping excess dirt and moisture off the blade by giving it a couple of swipes on the sleeve of my shirt or coat, or perhaps trouser legs. No oil - who has time to oil their knives in the field, much less in a combat environment? I haven't had INFI rust in the field, not in the winter, not even a little. I've had other carbon steel blades develop a little surface rust, but that really is quite meaningless. Once I get home, I'll polish them a little with Flitz or something, and oil them, and that'll take care of the issue, and only leave a little patina on the blade.
To store knives made out of non-stainless steels, wax and such are hardly necessary. All I do is spread a little mineral oil on the blade, and it's ready for storage. It's not rocket science - they're not so rust prone that they'd just rust away on their own. I've never used any wax on INFI. In fact, my newest Badger Attack and Game Warden are still sitting naked on a desk, and I haven't even oiled them once.
I wouldn't mind carrying a non-stainless blade in combat, or in the woods, or anywhere with the exception of diving underwater. For diving, you'll want something very stainless, or perhaps something made of titanium or the like.
are stored in their leather sheaths and no issues so far since 02 for a couple of them. I've left them out over night, by morning covered in dew, wiped er off and no patina.
