A Model 10 with a 4" blade would be a great steak knife...food paring/prep blade size.
The 3" seems a little small...the 5" in a public place would look scary and could get you arrested, and a 7" is out of the question, except for the Chef in the Kitchen.
But a 4" Mdl 10 would be just right to politely take apart a nice steak, roast, whatever, in a public eatery!
