Jack Crafty Flintknapping
@knapperjackcraftyAbout
My name is Patrick Blank. I am a professional flintknapper. https://www.youtube.com/@KnapperJackCrafty I've been posting flintknapping videos and related content since 2011 and I have over 2000 videos on this channel. If there's a topic you think I might have covered, from beginner to advanced knapping, you can do a YouTube search for "jack crafty (insert topic here)". Some of my videos are "No Talk" but most of my videos are narrated. My political leaning is Conservative (Classical Liberal). I mention this because I tend to express opinions on various topics including philosophy during my videos. Fair warning. Hehe! I sign my work with the channel name of Jack Crafty and with my initials PAB (Patrick Allan Blank) and the date (year) of manufacture. I have begun to use AI to help generate content in less time. This may be a shock to some, especially because the advanced technology aspect can clash with the "primitive" subject matter. My apologies. Updated 16July2025

Anything you can run a 1/2" or more flake with a pressure flaker. HEAT TREATING: Heat treat a few FLAKES of everything you got except HIGH GRADE Raw Stone, Obsidian, Dacite, Basalt, Hornstone, Sonora, Fort Payne, or Rhyolite. Start with flakes and spalls less than 1" thick for 200°F for 24 hours to dry it out. Then raise the temp to 275°F and hold for 4 hours. Let cool down for 12 hours. Chip and compare. If no difference, put back I at 200°F for 1/2 hour, then raise to 275 for 1/2 hour, then raise to 325 for 4 hours. Let cool down for 12 hours. Chip and compare. If no difference, put back in at 200°F for 1/2 hour, then raise to 275 for 1/2 hour, then raise to 325 for 1/2 hour, the raise to 375 for 4 hours. Repeat with temp going up 50°F until you reach 600°F or nice chippable stone. Whichever comes first. If no good result, or things blow up, let us know.
