Navaja Font is a very few letter types with the context of grunge style fonts offer hierarchies to differentiate words in sentences or paragraphs. With Navaja I developed a font family that meets this need. This family is useful to organize the information into a hierarchy with an eroded look. Its central idea mixes grotesque, geometric and humanistic letter conventions. This way, Navaja is a grunge-sans with dense proportions to make graphic design with eroded character. Its main purpose appeared when one of my customers asked me for a t-shirt design for a fan club of an important football player. For this reason its starting point were stained and muddy letters characterizing the toughness and coldness of the sport.
