"guillotine(n): a device used for execution by decapitation"
But ours just cut paper! Which they do very effectively. And unlike their French namesakes, ours all have fully featured safety guards to make quite sure nobody gets hurt!
Whether you use a Guillotine or Trimmer is mostly a matter of personal choice, although guillotines are slightly better at handling thick multiple sheets of paper and trimmers are generally more compact and rather easier to store.
