Seamless stream of line on the blade spine forms a small mound over the nail nick on the way. It starts again toward the blade tip and slightly recurves before reaching the destination. This is the peculiar design feature of the Aida. You may feel "Wabi" and "Sabi" in the Aida Trout & Bird. Wabi/Sabi is simplicity and/or elegance which is the keen artistic sense that Japan culture has fostered. The blade made out of super steel VG-10 is slim & sharp. The good weight balance promises wonderful performance. Although the Aida Trout & Bird is primarily a knife for fishing & hunting, it also serves you as EDC. Handle is available in wood, jigged bone, abalone or white pearl.
