I have some drawers that are roughly 16" deep and 18" wide.

The drawers are not deep, from 3/4" to 3".

Some of the drawers will contain things such as pocket knives.

The drawers do not have partitions.

The drawer bottoms are slick so I was thinking about putting felt down on the bottoms since that will add a bit of friction to keep things from sliding around too much.

I have never done anything like this, but, especially with the shallow drawers, i really don't want to try and add dividers inside the drawers.

Any advice? I assume that I can just go to a fabric store and purchase felt and then I should use some kind of spray adhesive before putting down the felt.

Any other suggestions if I want to just not have things sliding around as much.

When I did something for fountain pens, I purchased an insert that I could cut with scissors that holds each pen in place. Don't think I want to be that precise with these drawers. Pens are very uniform in size, knives, not so much.
