For instance, carbon coated stainless steel is very unlikely to bend or break even when a lot of force is exerted on the knife.

How to Clean Dive Knives After Saltwater?
Dive knives need special care routines and if these routines will be followed correctly than an average dive knife will serve you for decades to come. Firstly, dive knives are best washed under a stream of running tap water with little dish soap right after diving as such action will ensure that the blade does not rust or corrode.
If you do notice rust spots do not use bleach or other harsh chemicals but instead soak the knife in the vinegar solution and rub the spot with baking soda for the best result. Also, make sure to rinse thoroughly and then dry the blade with a clean cloth so as to prevent the rusting from occurring again.
Furthermore, even if you will be just washing the knife make sure to dry it anyway using a clean towel right after the wash and never leave the knife to dry on its own. Moreover, you might want to sew a special sheath or buy a knife storing box if the knife was bought without these accessories. Lastly, always check what kind of sharpeners your particular dive knife requires.
Why is Serrated Dive Knife Not the Best Choice?
Most professional divers and avid collectors admit that it is very rare that you will need a serrated knife in the water. Serrated knives have a much shorter life span when compared to regular blades mainly because serrated knives are hard to sharpen. Plus, the process of sharpening serrated knives damages the blade with time.
Moreover, it can be very hard to find just the right knife sharpener for serrated knives because they cannot be sharpened using regular knife sharpeners. Serrated knives need a specially designed sharpener that is not just hard to find but also cost much more than a regular one.
Furthermore, serrated blades can also be hard to clean and maintain plus serrated blades are also harder to store as you would need to assign their own space away from the rest of the knives. On the other hand, flat edges are much easier to take care of and will often just need regular cleaning and once a year sharpening provided you use the knife often.
Moreover, today’s market has a wide range of flat edge dive knives including half and full tang blades. A solution to this problem could be buying a half serrated knife as these knives only have serration towards the front of the blade and not in the middle.
With such knives you can use serrated blades only when needed. Other times you could use it as a simple flat edge knife. Lastly, always buy knives that come with a warranty even if it is just the regular 30-day warranty. This will give you a chance to communicate with the manufacturer and ask for a replacement knife.
