I got myself these as a gift last spring:

They are absolutely amazing - definitely worth the money to get high quality, true left-handed scissors. They cut like a hot knife through butter.
I also have a nice pair of true left-handed Henckels, but I've had them since 1987 so I don't know where you would find them nowadays.
FYI for right handed people: true left-handed scissors are mirror images of right handed. If you set a pair of right handed scissors open on the table in front of you, the top blade will cross from upper left to lower right. On left handed scissors, the top blade goes from upper right to lower left. This allows the blades to be naturally squeezed together When cutting, and also puts the outside blade on top of the material so it's easier to follow a marked line.
