I used to have one of the original dyads with the micarta handle. I sold it years ago for what seemed a good price at the time - maybe around $140. I think I will need to get one of the new ones as the combination of fine tipped and serrated blades makes it a good companion to a more robust fixed blade.
On the Domino, I go back and forth. I like the pictures, then I think what's the point of a flipper, when you already have a leaf-shaped blade with a spyderhole? Also not sure what the point of the thick ti(?) liner on the CF scale side is. The leaf blade doesn't have a super strong tip, so what is the need for such as robust handle. I'm interested in it, but still on the fence.
