I am close. I got one of those racker files from a chain saw shop near work, and that got me a little sharper. It is a little more fine a cut than my 10 or maybe it is 12" file. I can cut hair, but not real easy like it pops hair. Good to go for hunting l am sure. I think I need a stone or jewel stick to get to the next level. That or a lot of stropping.
I know I can't get the same level of sharp feel as two blades. If I figured right, the angle on the blades is 68 deg. That is a long way from my average knife edges with angles from high teens to mid 20's for angles.
