Shaving in the stone age

He brags a bit, modern diamond-covered blades are certainly sharper (you can't test them on your thumb), but it's fun to watch.

I shave like a real man, with a machete! And no soap, water or mirror!

Surgeon use for obsidian scalpel blades
It's hard to believe but the sharpest knives that have ever been used in recent years were mounted with stone flakes made of obsidian

Obsidian is used by some surgeons for scalpel blades, as well-crafted obsidian blades have a cutting edge many times sharper than high-quality steel surgical scalpels, the cutting edge of the blade being only about 3 nanometers thick.[34] Even the sharpest metal knife has a jagged, irregular blade when viewed under a strong enough microscope; when examined even under an electron microscope an obsidian blade is still smooth and even.

Good quality obsidian fractures down to single molecules which can produce a cutting edge 500 times sharper than the sharpest steel scalpel blade ("American Medical News", Nov. 2, 1984:21). On the cellular level an obsidian knife can cut between cells rather than tear the cells as a steel knife will do. A sharper cut will allow a wound to heal more rapidly with less scarring.

Experimental, not allowed on humans.

Hey, it's just glass (with impurities).

For these "sharpest blades" matters, you may want to look at microtomes:
Microtomes use steel, glass, or diamond blades depending upon the specimen being sliced and the desired thickness of the sections being cut. Steel blades are used to prepare sections of animal or plant tissues for light microscopy histology. Glass knives are used to slice sections for light microscopy and to slice very thin sections for electron microscopy. Industrial grade diamond knives are used to slice hard materials such as bone, teeth and plant matter for both light microscopy and for electron microscopy. Gem quality diamond knives are used for slicing thin sections for electron microscopy.

Indeed, but microtomes do not usually litter the ground where Mormon boys can find them and play "circumcision".

Is it definitely determined that stone age men did not care for beards?

Stone age people in modern times do is not definitive because they may have been influenced by others.
