Did you lose your Doug Ritter folder in M4 steel at Burning Man this year? A gentleman who found the knife laying on the ground has contacted me trying to unite the found knife with its rightful owner. Kudos to him. We aren't sure if we have those records from back then, and it will take a while to dig them out to see if we do. In the meantime, identify the knife by size (Full-size or Mini) and serial number and we can re-unite you with your knife.
