I know I'm kind of late to the video, but you may be surprised to know that there are plenty of leather workers who still use bone tools like this. There are plastic and metal versions but they aren't as good or long lasting as bone tools. In fact, the more you use the bone tools they actually improve the job they do, edge burnishing leather especially. Being a tool made from a part of an animal they can break easier from misuse, but if they are treated carefully, they are tools that can last far longer than any other material used to make a similar tool.
I would like to add that the power tool versions can do the job faster, but the people who go out of their way to use traditional methods have found that the bone versions last longer and actually improve with use than the plastic or wood versions. Metal versions scratch and damage the hide, wooden ones splinter and wear out, plastic ones crack and break after a couple years. People who use the power tool versions simply replace the bit when it wears out as a consumerable item in their business. The faster work speed does make up for the added expense as doing it the traditional way is labour intensive, as I'm sure you'd expect.
I know of many. In short, just find a hammerstone, I usually unconsciously pick up quartz for this because it's heavy and dense, and start knapping rocks. I'm sorry I am not well versed in geology to know what many of these rocks I made blades from are, but glass is a good material to start practicing knapping with.
Melonic Randomizer those were cow bones from the supermarket that my wife makes bone broth with. In a true emergency setting in the woods it would likely be deer or elk leg bones which are very common
Hey Siska, thanks for watching! Yeah, it's very simple to make bone tools. All you really need is a hammer stone( a large round pebble) to break bones into smaller pieces, a flat anvil stone for abrasion purposes, and a few flakes of quartz or flint to make serrations. With those 3 types of stones you can make a wide range of bone tools like knives, combs, arrow heads, awls, needles, and fishhooks.
