Fillet knife recommendation?

[MVP]

It is not the handle that is problem with white handle Dexter yiu are use it is the blade material as they use stainless steel on blade which keeps nice and shiny but does not hold an edge. The wood handle version is carbon steel that look like shit from rust when not cares for but keep a killer edge that you can shave with. Look at what the mates use that do this everyday. Wipe done and rinse in fresh water and light coat of oil and put back in sheath if you ant to keep it looking pretty.
