One of the more iconic razors available is the Merkur Progress. Since the early 1950s, the 500 series has been available basically unchanged, changes in finishing excepted. Some other variations, notably the 800-series, have long been discontinued.
Based on an original patent by Walter Busch, of Walbusch-fame, see https://razors.page/patents/DE669899/, imho this sets the gold standard for adjustable razors.
To start with, I'd like to show you the very original Progress 500. Back then, numbering started with 0, and details were painted red.
