Even more narrow - you only need to know when to consider them.

I only ever bothered remembering enough of any algorithm to know my options and a few rules of thumb. If I ever actually need to consider the details of the algorithm, I certainly need to spend a lot more time thinking through the problem and its solution. Knowing a specific algorithm well enough to pump out in 15 minutes is a party trick that is as useful as being able to change a tire in 3 minutes flat. A great time saver that will be functionally useful maybe 3 times in your life...
