I've got one of these; the only difference between your photo and mine is that the gold lettering etc. in my lid is in worse condition. The spiral SB on them is not as coarse or thick as some of the other models, and is split in 3 sections, which seems to make for better "articulation". The blade holders allow for the blade to be slid out, which I guess is to allow them to be replaced in a "by day" set, if broken, chipped etc. Stropping in the approved method isn't very easy or satisfying (to me, anyway), but I have a holder which enables me to sharpen them on other stones, strops etc.The Wilkinson Sword 7-Day Empire Set is the one I would like to have.
