I would love to see a blade that's curved for more "bite" in the cut where it makes contact with the target. I'd also want it in a bigger size, and maybe also in this same size too, for a set of 2. 13 to 14 inches and 18 to 20 inches.

Granted, most branches and stems of things to be cut are already round, but even a very slight curve would still probably give improved cutting ability over a straight edge.

I'm sure something like that has already been thought up, but maybe it's not that big of a deal for most people's uses of these?
