I love the look of recurve blades but I'm not a big fan of them for most practical uses.

Advantages:
- I believe that you get a better "shear" effect on soft objects.
- You get more weight at the front of the blade so your center of impact is closer to the tip.

Disadvantages:
- Harder to get the exact angle for the cuts you want compared to a conventional straight blade.
- Harder to sharpen.
