I think one can get a straight sharper than a factory-sharpened DE blade.

I just tonight honed-up a nice PUMA I picked-up from eBay. Ran it through a meduim barber hone (EDGEMAKER), 4K Norton, 8K Norton, 13K Chinese Waterstone, then stropped on a TI .5 micron diamond-pasted linen strop, and DOVO plain leather strop.

The shave I got was unbelievable! Compared to my DE Merkur (Which I might sell) the straight gave me a MUCH closer shave, much quicker. And the DE kincks the hell out of my face (corners of the blades, I think).

In my opinion, a WELL honed straight with a high-quality blade can easily be as sharp, or sharper than a DE.
