 Does such a thing exist? It also needs to be non-polarized. For 120V US outlets. I guess I could work with a polarized one and just switch the leads if needed, but non-p would be better.

Leviton makes a two blade non-polarized plug but I would rather try something with some penetration in the audio world if it's out there.

 Then you can use any cord you want.
Naturally the debate over 'Will grinding down one edge destroy the sonics of the plug" could last for a near eternity.
I would say just be careful to not damage the plating on the flat surface...( done by making certain the grinder is cutting 'down' direction against edge of plating. So turn the plug over to grind other side to keep the cutting so the plating cannot 'lift' off the surface..)

Or use a fine file. same thing..

 plug. By that I mean where the neutral blade is wider than the hot blade. Can you provide a picture of one?

No such product, IME. Audiophile power cords featuring a 2-prong AC plug tend to be a molded AC plug. From a safety POV, a 2-conductor power cord can be terminated with a 3-prong AC plug; simply leave the ground prong alone, other than tighten the ground conductor termination screw down so it does not rattle inside the connector shell. If you must use a hardware store variety non-polarized 2-prong plug, avoid those with folded brass prongs, a nickel plated neutral prong, steel clamping plates, and "easy" wire piercing snap-on plug designs.

If I were to experiment with a basic bare brass non-polarized 2-prong plug for a non-critical listening application, I would consider this product (see link below):

 You are right, jea48. The position of the ground prong dictates polarity, so there is no need of a wider neutral blade for the purpose.

 and as pointed out, a 3-prong will not have a polarized blade. Since I'd be in some ways destroying an audiophile style plug, what would be something not stratospherically priced that would provide an open sound, leaning toward a nice solid bottom end and extended but smooth upper end? I'm building a new power cord for my Slee Solo Ultra-Linear Diamond head amp.

 The problem with that is that someone might rely on there being a safety ground, whereas there will be none. The code police would not like that approach either
