I like to keep a barakta on hand while fettling. Not only is she a source of inspiration for dubious bodges that just might work, not to mention skilled at holding things still in awkward positions while I do terrifying things close to her hands with some combination of a) heat b) electricity c) sharp implements d) a lump hammer or e) adhesives, but she also has a superhuman ability to provide the correct answer to rhetorical "Where did the fucking screwdriver go?" type questions.
I attribute this to a fundamental, yet unresearched, difference in cognitive style - she has the 'finding things' gene, where I rely on 'remembering where I saw them' (a strategy that works well until dealing with people who like to tidy things up, or objects prone to macroscopic quantum effects like recently-used screwdrivers).
