I’ve linked before to Tim Rast’s excellent blog ‘Elfshot’, which chronicles his work in Newfoundland, making replications and experimental archaeology for love, and money. Or, as he puts it, “Making a living as a 21st Century Flintknapper.” You can buy some of his superb work here and also browse part of his impressive back-catalogue of reproductions here.
Recently Tim has been going beyond the call of duty with a fantastic series of detailed, superbly illustrated (for the strong of stomach – photos and videos) on preparing the hide of a hooded seal, and the associated fun of processing its intestines for technological projects. I urge you to go read them in their entirety over at his blog.
Seal intestines were, of course useful for any number of tasks.
