I should add that if you are talking about dried sausages, then the extra weight of a chef's knife is good. Those sausages aren't very tall and you aren't taking thin slices so you aren't worried about drag from all that surface area.
The reason I excluded tomato knives, which also reduce drag, is because they are so often serrated and crappy.
A salmon knife is almost ideal, being made to reduce drag on a very delicate meat. But it's too long for what you need and an oddball in any knife kit.
