Triangles.
A triangle is a platform from which I see a lot of different styles of tools originate. There were several methods I see used to make triangles. Finding the next piece kind of blew my mind. For some reason the maker stopped before it was finished. you can clearly see the that the entire piece is covered in pecking marks.


A different, larger piece made using the same technique. You can see the common orange colour residual stain covering this side.

The other side has some residual stains and a lightly polished concave groove running down the left side.

Another piece with some orange residual stains that was made using the same technique. This piece has nicely ground smooth edges

Another tool from my collection that was made using the same technique.

These were all made using the same technique.
