without using a coating what is the best way to get a nice matt finish
i hand sanded with 320 grit but to me its still has too much glare
im thinking sandblasting but is there any other good ways i would have to get the blasting done by a friend
its going to a marine and must be matt
thanks for the help

Ferric chloride, AKA PCB Etchant, available from Radio Shack will provide a pretty even matte surface if you don't wish to bead/sandblast. Mix it 50/50 with distilled water wash the blade good and set in in the container with the etchant for about 5 minutes. Take it out and scrub with a steel wool pad, under running water, and see if it's dull enough. If not stick it back in for a few and repeat the process.

You can reuse the ferric chloride, so don't throw it away because it may change color when you use it, if you do.

Yep, just like grinding belts don't care what kind of carbon based steel goes into them, neither does acid. It will eat them all.;)

I've used in on 440C which has a lot more chromium in it that CPM154 and no problems at all.
 
Butch,

Let me know if you need some FeCl. I've got some here @ the house.
