Wendigos are still capable of humanoid shape and presumably keep semi-human intelligence so, it's a reasonable assumption that they'd be able to use weapons albeit not as well as a normal human. Skinwalkers by contrast prefer to take an animal's form to attack mostly wolves or bears, so them carrying a weapon is unlikely unless they're still in human form.
