There isn't a heck of a lot of written material out there but they are mentioned in some manuals of survival training and there are suggestions in the modern day US & British Army survival manuals written for the Special Forces group in both countries. Don't know how much this will interest people but, I thought to pass on some personal knowledge I gained over the years. I have never hit any wild game with a sling as of yet, but one day it will happen. BTW I love rabbit and squirrel with dark gravy and corn bread or biscuits. I don't think it gets more primitive than a Throwing Stick, how about you?
ishii,
If you can find it on here (I just looked at it) I posted a summary of an article from American Antiquity Vol. 8 No. 1 July 1942 titled "Grooved Clubs and Modern Rabbit Sticks" by Robert Heizer.
The thread/posting here was on June 23, 2005 called Grooved Clubs and Rabbit Sticks. Sorry, I don't know how to post links to other threads here yet.
By the way I just came back to western NY after living out of state for 3 years, so I've been away from this board for many months.
Hope you find it interesting.
