Bent rather than cut into a bend, or even carved is probably going to maintain the strength of the wood better. Any cut out, or carved out shape will ultimately have a grain change right where you are placing the weight down onto it, and it's there where you will see breakage if the grain isn't helping to support weight. Bending it maintains the integrity of the woods strength, and usually will fare better.

I knew an old guy who mostly just made canes, and he would say make 10 canes, 5 would be decent, 2 or 3 really iffy, and a couple of just plain fails, so I always took from that there was no always way to get them right, because to look at his, they were all done the same. He was a bender, and had as much time in the curved molds he used, as in the canes themselves.
