You know you can use clippers to go 'with' the direction of the hair or 'against' it.
If you prefer your hair longer, you can use the longest guard on the clippers and run it through the hair downwards, towards the neck.
This blends in the piece quite well but keeps the length longer.
I regularly use a blades 4 & 5 and work it through my hair at the back & sides starting from the crown and moving it downwards.
