Okay, let’s try this again. Did you read THIS POST:
Did you do a search of IFI for threads on heat-treating O1?
https://www.google.com/search?q=iforgeiron.com+heat+treat+O-1&ie=UTF-8&oe=UTF-8&hl=en-us&client=safari
What SPECIFIC questions do you have about heat-treating O-1? Have you ever worked with it before? Have you made blades before? Have you made a sword before? What kind of equipment do you have? Etc, etc, etc.
Please understand that people here WANT to help you, but you have to do your part (that is, by giving good background, asking specific questions, and not expecting to be spoonfed information that’s already been discussed) first.
