You're on the right track
The 1200 normalizing soak is by the book so don't skip that. The book I followed at work was The Machinist Guide to Heat Treating. It's in the machinist handbook. Ray is correct on the double temper, but at work we didn't bother and when I made myself knives I didn't either and HT @ 1490 for 1/4 and 3/16 thick O1 per the one hour per inch rule after allowing three minutes to ramp up. I tempered at 450 dead on as measured by tempil sticks in an old electric stove we had. I would also heat treat 1095 knives with an oxy-acetylene torch with a big rosebud tip. Got nice Hamons doing that without trying.lol
