These Dalton knives are designed much like the knives/saws of Paleo and Transitional Paleo peoples. They are 2 sided blades hafted with real pitch and sinew into your choice of a rustic bone handle or a natural wood handle. While they certainly look good, these are not polished and finished handles like more display pieces. These err on the side of authenticity. I personally recommend flint/chert for actual use but dacite and obsidian do work as well, they just dull a bit faster because the edge isn’t as robust. Below are sample pictures of what they will generally look like. Bone and wood handles are natural so they will vary slightly.
