heat treat o1 at home - questions

I am making a wood carving knife for myself and this is my first homemade knife.
I want a thin blade and will use 1/16 thick o1.
I know that 10x is better than o1 for beginners but I got a very good deal on the o1 and could not find 10x in 1/16.
The blade geometry is as follows: 1/16 thick, 1.5 inches long, 1/3 inch wide.
Heat treat process
1) heat with two propane torches, one on each side of the blade.
2) test with magnet until the blade is non-magnetic.
3) Once the blade is non-magnetic I will soak or continue to heat for 3 minutes trying to keep the same color.
4) after the 3 minute soak dunk straight into a glass of canola oil heated to 125 degrees.
5) after it cools bake in oven at 400 degrees for one hour
question:
1) should I put a dull edge on the blade before I heat treat, I have read that the blade edge should not be two thin?
2) i used this url to calculate soak time - is minutes correct correct http://htsteel.blogspot.com/p/heat-t...ool-steel.html
3) does the heat treat process I am using sound reasonable?
