There is little correlation between the price of a razor and its shaving quality. You could buy a $40 Eboy special and with a little work have a gleaming dead accurate shaver that will shave as good as a $1000 custom made razor.

When you pay more for a razor your paying for many things; name, condition of razor if vintage, if custom reputation of maker, fancy work and scale material,rarity and that elusive what the market will bear and collectivity and competition with collectors and users.

I don't think blade materials affect the price with vintage stuff. Whether it's stainless or Carbon or Swedish Steel or Sheffield Steel or a singing blade doesn't necessarily affect the price. Damascus yes but that's a special case.
