Swiss formula on knife blades of O1 tool steel
Good morning, Bob,
I am using your Swiss formula on knife blades of O1 tool steel. The color is stunning! I'm curious whether the Swiss would be able to attack and color D2 tool steel. D2 is is high carbon alloy with a fairly high chromium content (nearly stainless) but I like the deep Grey-black of these O1 blades and would love to be able to create a similar patina on some d2 blades.
Please let me know.
Thanks
Jay G.
