Yeah, I don’t know. Here is an interesting quote from the guts and grease article:

“According to John (Fire) Lame Deer, the eating of guts had evolved into a contest. “In the old days we used to eat the guts of the buffalo, making a contest of it, two fellows getting hold of a long piece of intestines from opposite ends, starting chewing toward the middle, seeing who can get there first; that’s eating. Those buffalo guts, full of half-fermented, half-digested grass and herbs, you didn’t need any pills and vitamins when you swallowed those.”15″

Don’t know what tribe that is, how far north did the buffalo roam?

no matter how sharp your obsidian knife is I wouldn’t recommend trying to hack through the sternum with it. Its just too brittle. Maybe an obsidian hand ax would work, but I don’t think it’s necesary. I’ve field dressed deer, antelope and elk and I don’t cut through any bone. this just means “freeing the anus” like Urban Scout said, and being willing to reach into the chest cavity up to your elbows. A little messier, but then it’s a messy job to begin with, and the edge on your knife will stay sharper.

Well, one would substitute the gun with a sling, but what would the future hunter substitute the bonesaw with?

I believe he mentioned at the beginning that he’d shot the deer with an arrow–granted, it was probably one of those expensive, store-bought bows, but it was at least in the same family. As for a bone saw, this is where stone tools come in. A good obsidian knife will be far sharper than any of his tools in the video.

But of course you’ll also want to not be learning how to do this from a YouTube video.

Which is why I don’t really write about skills. There’s not much to write about. They’re all pretty easy to understand, it’s the practice that’s essential, and there’s nothing anyone online can do for you on that account. I find these YouTube videos helpful to the most extreme novice who might not know the basics. They shouldn’t be taken for anything more than the most absolute introduction to the most general form. As Devin and others have pointed out in each case, they often suffer from significant problems in the details.

I was kind of hoping he was going to suck the fermented greens out of the guts….

That’s a practice pretty much restricted to the Inuit and other polar groups, no? Most groups are able to get their greens in much more palatable ways.

But of course you’ll also want to not be learning how to do this from a YouTube video.

Oh well.

When your making your incisions, no doubt you should be careful not to cut too deeply or forcefully in order not to puncture the large intestine where the feces are.
