good day all i finished making a knife for my mom the other day and have been using it in the kitchen... sharp strong yada yada... but after a week of use i polished it to a mirror finish the steel has changed colour? ive scrubbed it no change? is 01 suitable for a kitchen knife? i understand they take a little more maintaining but i didnt expect the finish to change?
Any high carbon knife will change colour or patina with time, it is not going to stay nice and shiny. I give my 52100 knives a quick dip in ferric chloride and then dab mustard on them for a few minutes . This gives the steel a a dark blue patina and keeps it from rusting.
I've done a few kitchen knives in 01. The food juices (technical term) change the colour very quickly.
