154CM in a diveknife?

I have had a Benchmade Nimravus Tanto for a long time, and I have never really found a use for it.

Now I am considering making it my diveknife. (I already use a KATZ Diveknive, but a second diveknife won't hurt)

So, how would you guys think 154CM would fare in saltwater?
 
You'd still have to wash, dry and oil it to keep it from rusting after every time you took it out.

It would be an expensive loss too... Better off using a blunted steak knife from a 2nd hand store that you wouldn't be bummed on if it got lost.
 
I took my griptilian in 154 out to the beach, where it stayed by my side for two days. The only issue I had was rust along the edge, and a little by the logo. However, my blade is coated and also I did a very thorough cleaning each night. I would look for something different
 
It's just a production fixed blade. If you can afford to replace it or spend time getting it touched up, go for it.
 
It's not going to just magically turn into a piece of rust....

You can dive with it, it is a full stainless steel, and it will be fine as long as you make sure to wash off the salt and dry the knife.
 
Well I would rather lose it while using it, than not use it at all.

Bought it some 10 years ago, because it looked cool.
Since then my interest has progressed towards knives of a different nature. Thus making my Nimravus sit idle, while I go hiking or camping with all my other blades :)

If the blade won't wither and die from exposure to saltwater, then it will get a new job soon:thumbup:
 
Take it with you diving.
I you care of it, it will care of you.
While it may not be the optimum, BM made knives with diving in mind, it will sure fill the needs.
Just think of early UDT's and their equipment.

should work just fine. I use a couple of 154CM knives for fish cleaning on the boat. Just wipe it down when you get home.
 
I will give it a go, as my diveknife.
I do underwater hunting/spearfishing, so the thin and very pointy blade will do well killing off the fish.

And the serrations will come in handy, going through fishbone.

I always clean my knives after use. Most of my knives are carbon steel.
 
I was a SCUBA instructor and commercial spear fisherman for a good part of my life. I have always collect knives. For the life of my I cannot understand why anyone would even want a sharp knife to go diving. Only the human ego makes one carry a sharp knife in the water. There is absolutely nothing in the water that requires a sharp knife. Killing a fish? forget about it. A disposable ice pick works much better. Actually the spear point works just as well in killing a fish. Clean fish in the water? Why not wait till you get back on land. With the motion in the water a sharp knife is more likely to cut up the operator than anything else. Fighting off a shark? Only in the movies.

The only time when a knife is useful is to cut off fishing lines tangled about the diver. A sharp knife will not help you at that time. A good serrated edge will do the work much better. You have a lot less dexterity while in the water. You are wearing a glove. The water is sloshing around you. Things maybe bumping into you or you are bumping into things. Only the inexperience will fantasize about taking a sharp dive knife with them.
 
Appreciate the input!
So far, using a pointy diveknife, has not caused hazardous situations to me. But I certainly understand your point.

Rest assured, my concern is not sharks:D
We have no sharks worth fearing here.

Getting tangled in nets or fishline is however a concern. Therefore I would never get in the water knifeless.
 
I have 0 diving experience (save for snorkelling a couple of times in Croatia), but there was a post some time back on similar topic (blade shape and type) where an experienced diver recommended serrated blade with no point - Something like Spyderco Enuff or Jumpmaster.
 
I would not waste a 154cm blade in the ocean. There was a time when I carried a cheap ATS34 gerber folder with me in the water. One day I left it in my wet suit when I got back from the ocean and the next day it was 100% covered by a layer of surface rust. It wasn't hard to scrub away, but after that, I just carried a dive knife in an ankle holster. 154cm/ATS34 are actually very low in Cr so a 440A/B blade will be better for that if you have to. Also cheaper
 
Spydercos H1 knives work well in salt water, I see them on the exchange here for a great price. You can even put it in the dishwasher to clean it.

Very low carbon and lots of nickel help it. I think there are several stainless blade steels that are near 20% Cr, which should work as well
 
If your Spearfishing your already carrying a long sharp pointed spear. Some of the fish you kill have very sharp pointed spines. Which can penetrate all the way through your thumb nail. Don't ask me how I know that? And some of you are worried about carrying a pointed knife?
