Thank you for the replies! I was thinking of getting the Ambassador simply because I want the 74mm knives, but I think there are some redundancies or unneeded tools in the Executive. The two blades of the Executive could be replaced by a single one considering that both are really in the small blade category. The orange peeler seems to be very interesting but other than the screwdriver tip and the fact that it could be a good novelty for a fan of MacGyver like myself, I don't think I will get use from it that I can't also get from the blade. Also it kind of worries me that my screwdriver has a blade on the shaft. The longer and far better nailfile from the Executive could be replaced by the one on the Ambassador even though, let's face it, the latter pales in comparison. And both SAK's have scissors so they're equal in that department.
So I'm kind of convinced that the tools I will use the most from an Executive are also those that I can find from an Ambassador. Hence my inclination to buy the Ambassador over the Executive. Also, having no key ring near the blade might help.
