You can try making knive out of stone. I would use something like flint or quartz. That would be cool! Honestly, I tried making it myself but I don't have the grinding powder paste to do it and I used up many sheets of aluminium oxide sandpaper. It would take forever.
I think you need to use a food-grade liquid hardener if you are planning to use it for cutting food for consumption. The idea is great. It could be very useful if you take it seriously and on another level.
