As a trout fisherman, it's never seemed necessary to me to sharpen hooks, even after a given fly has caught fishies on multiple outings. I fish moving water almost exclusively, regularly catching trouts ranging from 4-5" brookies to browns over 20" with a large majority being bows, cutts, and browns in the 10" to 18" range.

Just wondering if others make it a habit to sharpen their hooks, and if there are different approaches taken by folks chasing different species, or bigger trouts ??
