A utility knife is great for chopping smaller foods and vegetables, like shallots. It shares many of the qualities of a chef knife, but it can be a useful tool when working with smaller food items, as the utility knife allows for more precise cutting work.
AEB-L is an expertly designed steel, balancing high hardness with good corrosion resistance, and maxing out the amount of carbide that still maintains high toughness, sharpness, and blanking performance for razors. Those qualities make it a good knife steel in many ways as well.
With its high toughness and good potential hardness, AEB-L excels in applications requiring thin edges like razors, fine slicing fixed blades and folders, and kitchen knives. Especially in knives where corrosion resistance is desired. It also does well in knives that require high toughness that will be subjected to hard use. It is not a good choice for applications that require very high slicing edge retention or in very corrosive environments like salt water. It is an especially good choice for those that prefer simple carbon steels and low alloy steels but would like to try a stainless steel. AEB-L will behave more similarly in grinding, polishing, and end user properties than many other high wear resistance stainless steels.
