If you don't do restoration or pinning, it will be rough going. You might look for ones which are fairly common and come up for sale often. First you should decide what type you like. I had a 7-day set of Case Red Imps. It was cool for a while, but the variety was being missed after a while. Then, I hunted down Wester Bros bone scales and installed 7 modern grind wedges from different makers. Also cool for a while. The variety was still somewhat lacking. I have a 7 day set of Brooks and Crooks in ivory, but alas, have not used them. All the same. You might think about a common theme, yet with something in common like scale materials, or a single maker with 7 different styles. (Henckels is a good bet!) If something was to happen to one, it could be replaced with another close. I have done 2 sets with identical scales, yet different blades, one set all Henckels, one all American makes. It took f-o-r-e-v-e-r. They do, however, have variety! Next set I do will be same scale material and anything quality will go for the blades. I like mixing wedges, half-hollows, framebacks, and thinner grinds. If you want them all EXACTLY the same, it will be a journey, unless you just buy 7 new ones.
Question is, how patient are you?
