J. Kelly Posted December 24, 2020 Share Posted December 24, 2020 Can anyone tell me the process used to achieve this type of finish. I am having a knife made and would like to have the blade look something like this. Thank you in advance for any thoughts or help Quote Link to comment Share on other sites More sharing options...
Welshj Posted December 24, 2020 Share Posted December 24, 2020 I think that's been painted, or Hydro dipped. There's no method otherwise- that I'm aware of, that gives clean lines around the colors with no blending. Those are overlapped, or printed and dipped.

George N. M. Posted December 24, 2020 Share Posted December 24, 2020 The blues and purples could be oxidation colors but the canary yellow, brown, and the black are not. They are either some sort of pigment (paint or other pigment source) or an odd iron oxide created by what I suspect would be some pretty exotic and possibly dangerous chemicals. The black and even the brown could be the result of reasonably benign chemical reaction but the yellow is not something I have seen. Even limonite, an iron ore, which can be yellow and is FeO(OH) is not that canary bright yellow. Getting an OH ion in there might involve strong alkali reagents that I would want to mess with. I personally do not find the color combination or pattern particularly attractive but that is just me. Different strokes for different folks. "By hammer and hand all arts do stand."

ThomasPowers Posted December 24, 2020 Share Posted December 24, 2020 Looks like anodized titanium to me. Which would make a pretty but low grade blade. (I forged a CP1-2 Ti eating knife once and had to take a plain old carbon steel knife and cut a sliver off the spine to show folks it's not some super metal for knives---save for dive knives where the corrosion resistance outweighs the edge holding properties.)

George N. M. Posted December 24, 2020 Share Posted December 24, 2020 Thomas: I didn't even consider the idea that the colored blade was not steel. Titanium would explain a lot. Good call. "By hammer and hand all arts do stand." Quote Link to comment Share on other sites More sharing options...
ThomasPowers Posted December 24, 2020 Share Posted December 24, 2020 Don't know that it isn't steel; just the colours sure reminded me of the reactive metals. Quote Link to comment Share on other sites More sharing options...
Irondragon Forge ClayWorks Posted December 24, 2020 Share Posted December 24, 2020 That is about the ugliest knife I have ever seen. Quote Link to comment Share on other sites More sharing options...
J. Kelly Posted December 24, 2020 Author Share Posted December 24, 2020 Thank you all very much for your input. I had to laugh at the last comment about how ugly it is- thank you for that. I am looking to have a railroad spike knife made so the metal will be iron. I got pointed to the newbie helpful tips just now so I really appreciate your thoughts on this even though I may not have been as specific as I could have been. Not sure of the metal used on the pic I attached but if it is the paint method, will that hold over time or does it eventually wear off?

Steve Sells Posted December 24, 2020 Share Posted December 24, 2020 It will wear off sooner rather than later with either oxides or paint Quote Link to comment Share on other sites More sharing options...
ThomasPowers Posted December 24, 2020 Share Posted December 24, 2020 Any coating, including metal plating, will wear off with use. RR spikes are mild steel up to the boundary of medium carbon steel. As such in use they will need sharpening often making any coating near the edge last even less time for a using knife. Any reason not to use an alloy that is better for making blades?

Deimos Posted December 25, 2020 Share Posted December 25, 2020 What is it with people making Kerambits ugly, big and unusable. It looks hydro dipped indeed, from looking at the site where it is sold almost everything is made with 440 Stainless steel. Quote Link to comment Share on other sites More sharing options...
