012 Weird Nodule of Black Butter (Dacite) Obsidian Knife - Direct Percussion Biface Flint Knapping

After looking at the weird shape of this obsidian nodule, I decided to record the flintknapping process because I knew it would be a fun one to knap. This opaque obsidian appears to be what is commonly known as "black butter" or informally as dacite although I've never been fortunate enough to work with dacite of this quality. Most dacite I've worked is much more coarse-grained and prone to hinge fractures. This nodule is the only one of this type that I picked up from Glass Buttes and I wish I had more as it really feels like knapping butter. Thankfully, I was able to produce plenty of good flakes for smaller points during the bifacing process shown in this video.

Technique: Direct percussion with a copper bopper.
Material: Opaque black obsidian from Glass Buttes
