The petty knife is light and thin with a bit of flex to it and is used for peeling, chopping and trimming. Not used in a hammer grip way meaning you don’t chop up and down like a chefs knife due to not having enough clearance for the knuckles. Mostly used for cutting away from the chopping board but is essential for any knife roll and home kitchen. The general size of a petty ranges from 95mm to 150mm but can go up to 180mm but this is considered to be in a slicing categories.
