I need to remove a ding... only its not in my razor. its in my EDC knife. I'm looking for a little info before i "have at it" and make things worse

the knife is composed of a black titanium nitride coated AUS-8 stainless steel tanto blade.

I don't know how aus8 compares to a standard carbon steel razor.

I have a dmt1200 and norton 4k/8k.

because the blade is flat, I cant just rest it on the hone like a razor with spine... I'm not quite sure the best way to hold it to maintain an exact angle all the time...

I'm wondering if I should put a tonne of electrical tape and create a spine as close to the angle of the original bevel..

something tells me whatever I do I'll probably loose the original bevel...

Anyone have any ideas on the best way to clean this up?
