Dive Knives
It is essential for all divers to wear at least one dive knife, and it is also highly recommended to have a back up knife. Almost any manufacturer's knives will do, but bear in mind that you get what you pay for. The first choice is what blade alloy to buy. Stainless steel varies greatly in its strength, durability and rust inhibiting factors. For example, 304 series stainless offers excellent resistance to rust but needs sharpening often and should not be used for  prying. 420 series stainless contains less chrome and is less resistant to rust. This alloy is very tough and holds its edge longer then the 304 series. 440series stainless is a high carbon alloy. Blades made of this alloy will stay sharp for quite awhile. The down side is that the blade will rust and it is a little brittle.  Knives made of 440stainless should not be used for prying. As a main knife, I prefer to wear a medium size blade, solidly constructed with a portion of the blade serrated. This serration allows easier cutting of heavy rope. Other options available in dive knives include ground in line cutters and a solid metal butt on the backend of the handle to use as a tap hammer. I also wear a small sharp back up knife attached to the side of my gauge console. Other divers wear both knives on their legs or mount the back up knife to their buoyancy compensator. As aside note, many wreck divers choose to attach their leg mounted knives with the use of surgical tubing. By doing so, they simply pull the knives up their leg to the predetermined location and do not have to fumble with small buckles when suiting up. Others glue neoprene knife pockets onto their suits. I happen to enjoy the new elastic straps and quick release buckle connections that are now on the market. The main important adaptation that must be preformed to some store bought knives is that a diver's knife should be very sharp at all times. This is because in and around shipwrecks, we encounter monofilament lines, discarded penetration lines, anchor lines, and other nets and ropes of all sizes. Each of these could be potentially hazardous if entanglement occurred, and a good sharp knife will assure us an easy escape. A back up knife serves the same function in the case when a main knife is lost or cannot be easily reached.

One way to sharpen your knife is to simply buy a good cross hatched fine metal file from any hardware store. Don't try to get a perfect edge; simply file both sides and leave the ragged razor-like burr on the edge. It's this burr that will slice through rope better than a honed blade. The one down side to sharpening in this manner is that the knife will dull rapidly, so sharpening will be necessary fairly often. I recommend sharpening before each day of diving. Other more sophisticated sharpening methods include honing or stone sharpening.
