Removing rust from knives

I really never understand this, what do you think you're going to do
with that knife? Fight sharks?

A knife needs two qualities, it needs to cut line and be easily
reachable with both hands. A small, blunt ended knife which can be fixed
on your BCD (or better waistband of your harness) is all you need. Even
better is a small knife and a pair of strong scissors which are better
for cutting fish line than any knife.

On the other hand, if you have a $100 titanium dive knife then I have
some Arizona beach front property you may be interested in...

There are valid uses for knives. I haven't found anything that will
crack into a tin of tuna for my surface interval snack as quick as a
drop-point blue tang. But I didn't need the Ti versrion I found the 316
stainless was decent enough.

I carry a pair of EMT shears on the waistband of my harness, the blue
tang stays firmly in the lunchbox.

Other than puncturing your BCD/wing while trying to cut some line
entangled behind you, what else can you do with the point of a dive knife?

So far, I have not managed to puncture my BCD (former) or wing (current)
with a pointed knife or other implement. Frankly, it would be hard for me
to puncture my wing with one, even intentionally, let alone accidentally. I
could, however, puncture a runaway lift bag, BCD or drysuit? It doesn't
happen often, but it only has to happen once. I've not had to do this, but
you never know. I believe in being prepared.

The last thing I remember doing that required a pointed dive knife was
scraping some crud that accumulated around the edge of the lenses of my
mask. A blunt tip would not have fit. I have used the point to get a
damaged O ring out of my tank so that I could replace it and make the next
dive. I used both of my knives, the blunt one and the pointed one, to
thread one of my buddy's fin straps through an incredibly difficult to use
buckle while standing in the surf at the beginning of a night dive off
Lauderdale by the Sea. He held the light. Any time you need to get into a
small place, a pointed knife is likely to be better than a blunt one.

You mentioned killing sharks, which is not something I'm likely to try to do
with a knife, but if one were to chose me for dinner, I'd darned sure rather
have a pointy knife to try to discourage him that a blunt one. There are
those who are around to tell the story because they had a sharp, pointy
knife. While sharks aren't something you normally try to kill with a knife,
it's not all that unusual for spearfishermen to dispatch large fish with
one. The hole a spear makes will eventually kill all of them, but some of
us prefer not to be towed all over the ocean first.

Personally, I find it handy to have two knives. I have one on each side,
behind the waist D rings on my harness. The one on the right is pointy, the
one on the left, is blunt. Neither is anywhere near the center of my waist
strap. That's the most inconvenient place I've ever tried to carry one.
Neither is in a soft sheath, either. I much prefer something less flexible
to keep the point of my pointy one or the sharp edge of either of them, from
cutting something I did not intend to cut . . . my body, for example.

And where exactly in my post did I say anything about fighting sharks?

OK, Mr. Real Estate, who pays $100 for a Blue Tang?

For shucking oysters and opening beer cans, among other things...

Always a high priority during a dive...
