Hook anatomy and hook types
Partridge Nymph/emerger GRS12ST

You often want to tie a fly on a curved hook. This might be desirable when tying smaller bugs (such as the New Flee), smaller fry imitations or shrimps.
The Partridge hook is not stainless, but niflor coated which makes it almost stainless. These hook are generally very sharp, strong and has a good shape that lends itself well to many patterns.
Peter Loevendahl who originally made The Frede normally straightens the hook a bit before tying on it. this will give you a more straight shanked hook with a bend that reminds a bit of a Limerick bend.

Among the patterns that use this particular hook you will find Frede, The Flee, The New Flee, Omoe Brush, The Mymph and several others.
