For a little excitement you could try a fresh blade knapped from obsidean.
Very delicate edge and so sharp its scary. Have tried shaving with them. Tricky to get a way to hold it at a consistent angle but sure mows down stubble. You can throw the blade away (stone age disposable LOL) or convert to another tool once done. I have never done a complete shave with one though. I usually chicken out after a few strokes as it has sharpness that just oozes hurt you vibes.
