Hiya! Big fan of the horrors you peddle!

I'm starting my masters in biomedical communication in less than a week, and we have a very jam-packed anatomy course this term. I'm really nervous for it, so I thought i'd ask you the one question that's been on my mind:

how sharp are the knees meant to be?

thanks!

Sharp as possible without carrying risk of self damaging complications. Humans need spurs on all their outward facing joints for utility and combat purposes.
