How not to care for a $100 utility knife

This is just simply embarrassing. In the spirit of Chinese Communist Party Self Criticism, this being the day the Soviets - er, the Chinese - launch their first cosmonaut into space on a 40 year old Soyuz design, I'll criticize this blunder of mine:

About a week ago, I mentioned a scuba diving trip I made to Monterey, California. If you look closely at the picture in that article, you'll see attached to the left side (my left side, as pictured) on the BCD (bouyancy control device [vest]) a Cold Steel Recon Tanto in its Kydex/Concealex sheath. Well, I was so knackered from the surf zone re-entry that I didn't immediately clean off my gear with fresh water and dry it. I did that the next day, forgetting completely that I'd clipped several caribiners (which survived unharmed) and one nice high carbon steel tanto (which suffered) to my technical BCD.

If you look closely at the snapshot above, you'll see rust spots on the exposed cutting edge of the blade. I took that photo as a record, before I cleaned up the edge. It took me an hour of careful work, but I was able to stone out and hone the rust spots. If you ever have anything like this happen to your blades, fix it thoroughly: one oxide spot will catalyze a larger oxide surface. I can say, however, that I'm really pleased at how the rest of the knife held up: flawlessly. The black epoxy powder coat finish protects the body of the blade extremely well.

I'm still going to try to dive this knife again, but next time I will 1.) pre-treat the entire blade surface with oil and 2.) immediately clean and dry the blade as soon as I doff my diving gear. Also, I'll use the same Nonox rust cleaner/preventative I use on my swords as an additional level of prevention in the cleanup.
