gmm243 Posted January 6, 2023 Report Share Posted January 6, 2023 Got given 2 Mora knives as a present. One I think is a Companion which has been great for all my deer work. The other is longer but I am not sure of the model. I thought all of them had a stainless steel blade but mine does not seem to have. Photo taken after washing and left on the draining board in the utility for a few days. Is it possible that there are different types of steels used for their blades? Can't make out any writing on the blade to point me in the right direction. Looks like I will be getting the wire wool out!! Quote Link to comment Share on other sites More sharing options...
Luckyshot Posted January 6, 2023 Report Share Posted January 6, 2023 You can get carbon steel blades or stainless steel blades. Quote Link to comment Share on other sites More sharing options...

oldypigeonpopper Posted January 7, 2023 Report Share Posted January 7, 2023 Hello, that's more like a carbon blade, although stainless will tarnish if left any length of time with blood on , they are not expensive to buy new, ? Quote Link to comment Share on other sites More sharing options...
Ferretlurcher1970 Posted January 7, 2023 Report Share Posted January 7, 2023 Although carbon blades require a bit of care, the edge is outstanding. Quote Link to comment Share on other sites More sharing options...
Loki Posted January 8, 2023 Report Share Posted January 8, 2023 Hi Once cleaned up with 0000 wirewool, degrease it and give it a soak in Citric Acid, available in powder form from chemists or Homebrewing stores. I use half a level teaspoon to enough hot (3/4 boiled) water in plastic beaker to cover blade; leaving until water goes cold. This puts a black 'passivation' coating - bit like PVD on watches, which protects the carbon steel. Repeat as necessary when coating seems to have been damaged or thinned from use. Also works on 'stain-less' steel blades, but does not blacken. L Quote Link to comment Share on other sites More sharing options...
Rim Fire Posted January 9, 2023 Report Share Posted January 9, 2023 I had similar happen to this but after a few times on my strop it came back to original state Quote Link to comment Share on other sites More sharing options...
gmm243 Posted January 11, 2023 Author Report Share Posted January 11, 2023 Thank you all for the replies. I actually got tied up with other things in the last few days so bar rubbing down the blade with a bit of kitchen roll I haven't done a thing. Will get into action tonight. Would never have dreamed of the citric acid treatment,will have to give it a go. Even though the knife is covered in rust the blade is still razor sharp.

John_R Posted January 12, 2023 Report Share Posted January 12, 2023 You can also do a patina with white vinegar. It forms a matt grey finish. Quote Link to comment Share on other sites More sharing options...
activeviii Posted January 15, 2023 Report Share Posted January 15, 2023 White vinegar and kitchen foil. Will clean it back, then one sorted and resharpened then just a bees wax paste on the blade detween uses will help hold the rust at bay You can chemical patina it, bit like gun blue, and that will help no end too. But end of day, carbon steel needs looking after. Quote Link to comment Share on other sites More sharing options...
