A prep knife is a little longer than paring knives, shorter than most chef's knives and is super sharp to make short work of whatever you need to cut up. In a pinch, I've even used a prep knife for boning. This prep knife is a good one. The good size sculpted handle is comfortable, even if your grip isn't as strong as it was. 

I really like the Signature line of knives because they are stamped from one of Zwilling's top quality steels. The craftsmanship and precision with which they are made gives me confidence that I will be able to enjoy them for years to come. Lighter than forged knives, this line is very popular. The sculpted handles fold into the palm of most people’s hands comfortably. The steel is strong, stable and holds an edge well. They can be and should be sharpened regularly. I recommend hand washing so they always look like new; but they are dishwasher safe.
