"Keen" is and adjective, used to describe something as sharp or acute. "The sword had a keen edge." "He was a man of keen intellect." It can also be used to express enthusiasm. "He was keen to learn another language."
Keen is an adjective. It is used to describe a noun or a pronoun as sharp, or finely sharpened. Examples include a keen edge, keen wind, keen eyes, keen mind.
Keen as a been makes more sense. Who the heck would say keen as a lemon? One must consider the relative intelligences of the vegetable matter. Is a bean, in fact, more keen than a lemon? Could lemons not be a misunderstood fruit, perhaps with unrecognized wit and wisdom? Is someone less keen just because they are sour and yellow? Perhaps we should reconsider the traditional simile.
With these examples, you could replace the ones that have 'like' with 'as' and it will still be a simile, and vice versa. Silent like a fox. Sneaky like a fox. Sly like a fox. As red as a fox. As thin as a fox. As keen as a fox.
