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.

Ocean Master Stainless Dive Knife
Ocean Master Stainless Steel knives are
made of the rarer beta alloy, whose tighter molecular
structure provides the greater strength required for cutting.
The high abrasion resistant, stay-sharp
stainless steel edge moreover is rust free, a guarantee high
carbon stainless steel knives cannot make.
Ocean Master's Auxiliary Locking System (ALS)
improves knife sheath design by incorporating a secondary lock
to help prevent costly knife loss.
The stainless steel comes in three
different types of blades double edges, single edge, and blunt
Blade Length - 129mm - 5 inches
Today Ocean Master has elevated the standards of titanium to
ultra-high hardnesses without the brittleness. An advanced
process of custom formulating stainless steel specifically for
knives results in previously unattainable levels of strength,
hardness and abrasion resistance. Now built to meet even the
high standards of military specifications, Ocean Master
custom-formulated stainless steel knives can handle all the
cutting you need to do.
