Obsidian vs. Flint Debate Turns Violent at Annual Knapping Symposium

The 2026 North American Flintknapping Symposium was suspended indefinitely on Saturday after a long-simmering dispute between obsidian advocates and flint purists escalated into what attendees described as 'the most historically accurate violence they had ever witnessed.' The altercation began during a panel discussion when master knapper Duane Percussion stated that obsidian produces 'objectively sharper edges at the molecular level, and anyone who disagrees is knapping in the dark ages.' Flint advocate Margaret Cortex responded by holding up a chert biface and calling obsidian 'a brittle, temperamental volcanic glass that shatters if you look at it wrong,' adding that 'real knappers work with real stone.' 'She called obsidian fake stone,' said witness Harold Debitage, still visibly shaken. 'In front of two hundred people. You don't do that.' The exchange devolved when Percussion displayed an obsidian blade he described as 'thinner than any flint edge Cortex could produce in her lifetime.' Cortex responded by producing a flint blade she claimed was 'more durable than anything that theatrical glass could achieve.' 'Then they started holding up their respective blades and sort of waving them at each other,' said symposium organizer Linda Lithic. 'Which is when I realized that we were at a convention where everyone is carrying extremely sharp handmade tools and this was a safety issue.' The event was halted before any injuries occurred. Both knappers have been issued formal warnings and banned from next year's panel discussions, though they may still enter the competitive knapping categories. Peruvian knapper Carlos Flake, attending his first American symposium, observed the incident with bewilderment. 'In Peru, we knap in peace,' he said. 'We do not fight about which rock is better. All rocks are good. These Americans are very passionate about rocks.'
