My favorite knife is the one pictured below. It's a thin and easy to sharpen knife that you have to get at an Asian market. Great for slicing potatoes thin, cucumbers, tomatoes, chicken and beef. The blade is about 9" long, and 2" high.
My next favorite knife is this Henckels cleaver. It's a dangerous knife and you could loose a finger. It is sharp and boy can in cut. The blade is about 7" long and 4" high. It's the newest of the bunch with a nice dishwasher safe handle.
The finale of my favorite knives is this heavy Asian meat cleaver. If you have something you want cut up, say chili meat, this sucker will do it. But keep one hand behind your back as it weighs about 2 pounds. No extra meat in the meat please!
We hide is one away unless we need it as it is a scary knife.
Oh, I have one move favorite knife. It's a Betty Crocker sandwich knife. I don't have a picture but it's about 5" long, 3/4" high and is serrated and excellent for slicing sandwiches in half.
