I have a razor that is 4/8 wide, and for some reason it does a better job under the jaw than any other razor. However, with the use of stretching and slicing/scything motions, I do pretty well now even without the narrow blade.
My skin seems to swell up over the whiskers to some degree when heated. After my skin cools down, it retracts down the hair shaft a small amount. I think this is what is happening, because in some areas, a BBS shave at the end of a shave is not quite BBS 15 minutes after the shave.
Now, this stubble reappearing phenomenon doesn't matter for most areas on my face, as I am getting a close enough shave that even after 15 minutes or more, it is still BBS. But, under my chin it is a different story! I am getting a nominal shave in the tough areas you mentioned. For this reason, now, I shave regularly. But, before my last pass I sometimes splash cold water on my skin. It seems to give me a better shave, as I am clipping the whiskers off just a tad bit lower than if my skin were hot.
