Errett Callahan - Piltdown Productions

Piltdown Productions

Upon his return from Northern Europe in 1981 Callahan founded Piltdown Productions. The company was founded as a means to sell his many publications, supplies, and instructional materials, as well as the stone tools and knives he produced. He first used the name, which he took from the infamous Piltdown Man hoax of the early 1900s in which British collector Charles Dawson attempted to pass off the jawbone of an orangutan and fragments of a human skull as an undiscovered human ancestor found in a gravel quarry in Piltdown, England. Callahan first used the Piltdown name in 1974 in a comic strip he drew for Experimental Archaeology Papers, or A.P.E.. In the comic strip he presented a humorous look at the life of a caveman. Callahan wrote two more installments of the comic for the A.P.E. and then for the Newsletter of Experimental Archaeology. During this period, he was also producing documentary and instructional films dealing with various aspects of primitive technology as well as beginner flint knapping kits and tool reproductions that he was sold to universities, colleges, and hobbyists around the country. Callahan has produced several catalog editions that contain not only his stone tool and instructional materials but a good deal of his philosophy and ethical stances towards the field of flint knapping.

Two of the more unusual items to be found in Callahan’s Piltdown Productions inventory are his nontraditional obsidian knives and his obsidian scalpels. The nontraditional obsidian knives, which Callahan began producing in quantities in 1984, are made with the same traditional tools as are his prehistoric replications; the nontraditional knives, however, are made into a large variety of shapes and sizes that are not based on any known prehistoric typology (Callahan 1999). Callahan originally began his work on nontraditional forms out of a desire to break out of the restrictions of traditional stone knife reproductions. His knives have won many awards and have often been featured in Blade magazine.

While his nontraditional knives were a way for Callahan to step outside the restrictions of the prehistoric typologies, his obsidian scalpels were a way for him to provide a service to mankind. The technology to make scalpel blades out of smoky obsidian, a volcanic glass that allows for the sharpest blade production, was first developed by the late Don Crabtree in the late 1970s. The blades, which have edges only a few molecules thick, are 100 to 500 times sharper than the traditional surgical steel scalpels (The University Record 1997). These ultra-sharp edges produce less scarring and tissue damage and speed the healing process. Though they are not popular in the medical field, Callahan’s obsidian scalpels have been used with great success in hundreds of operations, many performed by doctors and scientists at the University of Michigan Health System who have done extensive research using scalpels produced by Callahan.
