I think your point is valid in that if they're supplied to the army then they're almost useless in most situations, but isn't the idea of a SAK in the hands of a civilian to provide an afordable, useful array of tools which are quick at hand in a discreet way? I don't think anyone can expect them to do any serious woodwork if they want these features, and if they do there are other options.
Having said this, I have been tempted to buy the Rucksack (can't remember if this is the one I saw but it has an interesting skinning tool <img src="/images/graemlins/smile.gif" alt="" /> )mentioned by Doug.
