Thanks guys! Yeah that obsidian point was TINY....but it killed him so fast it was unbelievable. It was an Eastgate style point, with two long barbs. One of the barbs broke off a few days ago duue to rough handling. The other broke off when I hit the squirrel, as well as the needle sharp tip.
And yes, that is quite a long arrow, probably 33 inches or so. But it's spined for that bow and shoots beautifully. I also have some reed arrows that are a bit lighter and fly faster, but at close range like I was with this squirrel speed isn't as important as accuracy. Hell....accuracy is EVERYTHING. The bow is entirely primitive....grip is braintanned deerskin I tanned myself, and the string is twisted deer sinew that I made. I've used that bow to kill a number of squirrels, as well as a raccoon and that little sinew string is still holding up after several years. That bow has been shot hundreds of times, so if you don't believe a sinew string is durable, let me tell you from experience....they are!
