Rustproofing for new diving knife?

Depends on the specific alloy, but figure 1 to 1.5 mils (thousands of an inch) per 100,000 years. So your knife will be gone in..............although some low % titanium might be a lot worse. I would think, in normal use, it should be good for 1 or 2 million years.

So long as it's sharp, what difference does it make if it has some spotting anyhow? Unless, that is, you want it to look like it doesn't actually get used.

I have the same stainless knife I've had since the late 1980s, and yeah... there are a couple of tarnish stains. It's still one of the sharpest tools I have, and I've lost exactly zero hours of sleep over how it looks. When I last used it to cut myself out of monofilament, it wasn't a big consideration. Nor was it when I used it to filet dinner. In fact, when cutting food, I'd be a lot more concerned about "dirty" chemical treatments that had been applied than I would about not-so-shiny areas.

That's it? A lousy million years? I was told "forever"!

That's it, I'm writing a letter of complaint...

I would suggest waiting the 2 million years, take a picture and send it along with the "lifetime" guar. I'm sure any good company will send you a new one.

I do it to prevent salt accumulation inside the handle which I figure would be hard to get off once dried. Oh, and I love shining my toys... OK, it isn,t really shiny, but you get what I mean!!! It's probably not really usefull, what the heck...

Cheers!

No harm in doing so, of course, but no benefit, either. I have enough gear to wash as it is, that's why I bought all the Titanium stuff in the first place. Since I bought it, it came out of the sheath once to cut some cave line. Other than that, it lives in it's sheath and gets rinsed as it it were a built-in part of my rig. Love that!

Nothing wrong with a need to over clean things.. ok, maybe there is just a little bit.... but it sure will not hurt.

Rinse the knife and sheath after every dive, after it is dry give it a very light coat of oil and you will be fine. Don't forget to sharpen it every 3 months or so either. Lots of folks forget that one.

Titanium is the way to go for ease of maintenance. Holds an edge better/longer too.

Hmm... Don't know how to rust proof a knife, but the manufacturer of my stainless steel knife recommends steel wool to get rid of corrosion. I'm not brave enough for that though .

Why bother when you could get a super duper titanium rust resitant knife

0000 steel wool will not harm a thing and work wonders.
