Indigenous and Local Ecological Knowledge (ILEK) has been recognized for its potential and contribution to sustainable use of natural resources. It has proven difficult, however, to investigate and observe its tacit and embodied character. The objective of this article is to explore ways in which we can theoretically and methodologically understand ILEK. It does so by theorizing ILEK as craftsmanship using literature on practice theory, and analyzing the tacit and embodied nature of craftsmanship of a Sámi craftswoman and an archipelago fisherman through the use of visual methods. Results of this study are used to analyze and discuss how craftsmanship reproduces ILEK and its potential to contribute to environmental sustainability.
