For about four dollars on ebay you can buy a copy of the Parker. It's got a metal handle with what looks like two water drops punched through the handle, and it's the model with the flip-off blade lock that takes only short, half-double-edge blades, not long shavette-specific ones.

The basic construction is good--it's just the realization that's not quite there. As it comes, it doesn't work as well as it could, so I thinned the sides of mine by grinding the bevels more on a Japanese turntable grinder, giving it a bit more blade exposure and making a lower cutting angle possible.

After the hotrodding, it's one of my favorite razors. I don't find it particularly treacherous, because the blade is short enough to keep track of the whole thing, and it gets into places a longer straight can't. I'm wondering if I shouldn't just switch to it permanently, since I'm getting much better results than with a straight for a lot less fuss.

I've ordered another. I should probably shoot before and after pix so people who are mechanically inclined could see what I did to mine.
