A Test 3D Model of a Kirk Corner Notched Point

2/8/2016

Okay . . . I'm making some headway. Some of my 3D model creation issues are beginning to yield to good old-fashioned trial-and-error, and I've uploaded a test model to Sketchfab. The original is a Kirk Point from Allendale County, South Carolina. I didn't do full color capture on it, but I'll try one of those next. Take a look at the model and see what you think.

It reminds me of a little Romulin Bird of Prey from the original Star Trek.

What a cool tool to learn and use.

Very interesting. I don't think I have ever really taken a close look at the Kirk Points so always assumed the edges have been bifacially worked, but in this example, at least, I can see the edges were each worked from one side, although opposite sides for each edge.

Is that for balance?

The beveled edges are the result of resharpening on alternative faces. These "points" were used for cutting and sawing tasks in addition to (sometimes) serving as the tips of projectile weapons. Note that the edges are also serrated. When originally made, the point would have had a broader blade. This form of resharpening serves to maintain blade length as the biface is refurbished multiple times.

It looks burly, more like a stone bullet than a broadhead.

Wow, that's a lot of alternate-edge beveling and a really steep angle as well. That's very cool!

I have a cnc machine that may reproduce the point. I can work with many 3d file types. If you send me the file after some experimentation,
I will cut one from soapestone and send it to you.
Thank you.
