The thing i would say about karate chopping a rabbit is... lil while ago, i went out ferreting with my mate, p***y (nickname for reasons you can guess), and when a rabbit bolted he grabbed it went to karate chop it and the rabbit moved, didnt it and he ended up karte chopping a old ww2 gun implacment made of concrete...no even jackie chan would have problems cracking that. ironic thing is that the first time ive seen a rabbit move rather than just give up when you grab them.
i use a old ebony walking stick chopped down to clump em, or back of machete across the back of the head or just the
