Not much. The claw has a cutting edge. That's quite precisely what I wouldn't use for climbing...
[...] in how many forms? All, including Rahonavis?


AFAIK... yes, all. Definitely including *R.*.

But then *R.* has the toe bone proportions of a ground-dweller. *Archaeopteryx* is just on the terrestrial side of the line between terrestrial and arboreal birds in this respect...
