You didn't specify where you were looking at what is used for cutts in the salt or freshwater.

In freshwater my go to fly are Knudsen spiders, spiders, muddlers, reverse spiders, rolled muddlers, spiders, scuplins and spiders. throw in some crane flies and BWO and your set.

For the salt in addition to what has been mentioned candle fish and chum fry streamers can be very handy.
