I have offered to EN plate a knife for a maker, but no one has taken me up on the offer, so I'll make the offer again:
Entire knife should be 9" or less, made of carbon steel, polished the way you want it to look. Blade only- install handles after the plating is done. You pay the postage both ways.
The knife is to be USED, TESTED, AND THE RESULTS POSTED HERE.
Blades have been nickeled for quite some time, and they hold up well. Electroless nickel should work even better. It certainly will hold up better than any paint or bluing process.
