familiar with the 420 grade that many
fillet knives are made from to prevent
rusting, cheaper fillet knives can be
made from 304, 320 and 360 grades,
limiting their longevity. Stainless steel is
a combination of chromium and steel,
which results in a rust-resistant metal.
However, chromium causes the edge
of a knife to become blunt very quickly,
and during the manufacturing process
the steel is hardened to create a more


durable, longer lasting blade.
Grades of steel can vary greatly,
which is noticeable when looking at
the varying price points of knives on
a tackle store’s wall. Cheaper knives
may range from $15-$30, while those
manufactured from 420 stainless tend
up be upwards of $60. Even then, you
still need to look into what you’re buying.
Cheaper knives will end to lose their
edge quickly and some can easily begin

to rust in a short period of time, while
those of better quality tend to hold their
edge and are rust resistant.
There are brands aplenty. Those
familiar with the likes of Mustad, Martiini,
Swibo and Kershaw know that these
are the stand-outs when it comes to
filleting knives. The reason is because
of the high quality steel used in their
manufacture. For instance, Mustad uses
a high-grade German stainless steel,
