Serrated Scissor by Kai 4&3/4"
Kai makes some of the best scissors on the market! This 4 3/4" scissor is sturdy and very sharp, and it comes with a hard plastic sheath. It is serrated, which means that one blade is smooth and the other has little serrations that control the fabric as you cut.
I have small-ish hands and I find that the grips are very comfortable. If you have bigger hands you might prefer either the Havel scissor (which is serrated), the Elan scissor (which has smooth blades), or the Sewline Butterfly scissor (which is serrated and will be available soon).
