>Below is a link to a blog entry on wrote on why we designed our split nut driver the way we did. for 8.95 I think it's a good value and if you recall a thread on the subject a few weeks back cost seems to be an issue (and I certainly understand why) for an infrequently used tool. We designed our driver to fit in a standard 1/4" hex driver which these days is as ubiquitous as a 19th century brace and bit set was back then. A round shank would be cheaper but it wouldn't be as nice for hand driving.
