Knockout gets my vote almost just for its name. All the variants are based on different boxing weights. It is another design from the Hoefler and Frere-Jones type foundry, consisting of a family of 32 different sans serif weights. Knockout’s nine-width, four-weight family offers a range of options that cannot be achieved with even the best modern sans serifs. Most fonts begin their life with maybe just a regular, bold and italic version.
