broke arrow points

[larson1951]

a few weeks ago john gives me some coffee cans of scrapers and some that were full of mostly broke points or blades now this might be boring to some of you so you can always ignore otoh i am going to post two images of mandan arrow points the north dakota historical dept did an extreme and thorough excavation about the 'scattered village' which lies underneath eastern mandan, north dakota a survey and tally was done on the broke arrow points found it was their determination that 56% of the broke points found were broken during the manufacturing process (by the notch area) the remaining 44% were broke due to impact fractures in conclusion here are two images that illustrate and back this study i hope you can let me know if this has been of any interest to you

broke during the manufacturing process
broke from impact fracture

It's hard for me to say as I've never handled the type before but, each one looks to have use wear. I suppose if one were broke during a retouch it would still be classified as damaged during manufacture?

This is a calf creek style pt. that I made. Had it finished but I decided it needed one more flake removed to even up the notches. My notching tool touched the inside of it and snapped the base off but left the ears attached. I would guess that over 90% of the time it will be the ears that break. I have broke the ears off a lot of them but only once the base. This is a similar break as the old point I posted earlier. Although it broke straight across but it still left the barbs attached.

I have broke a lot of side notched arrow pts. while notching and they all had similar breaks as the ones shown as manufacturing breaks. I agree though that a hafted pt. could also break in a similar fashion.

Not to take away from the original post, but how have you snapped the base or ears ? By your tool making contact after the flake released or not enough support or using a punch to notch with ?

Deadeye, it can be caused by notching tool touching the side, not supporting it correctly, or by trying to remove to big of flake. There are probably other factors too and I'm pretty sure I've experienced them all. LOL

The notching tool making contact on the sides is the most common cause for breaking the base or ears.

Very interesting post Steve I enjoyed reading everybody's thought's. I think you may be right in your idea on breakage. When you find a broken one it always makes you wonder what caused it to break.
