Scud – The imitation of grammarus is one of the most effective artificial flies. Unfortunately, the hook is exposed to frequent contact with the bottom of the river especially during so-called short nymph fishing and as you well know a blunt hook is a bad hook. Why risk the loss of the catch of your life if you have Scud hooks at your disposal - they are highly resistant to abrasion and retain a significant portion of their original sharpness even after several fishing trips.
