Honestly, there is some redundancy there in this drawer. I admit it. I could slim it down. But that’s no fun. The collection must be massive.Holy moly - how often do you use them all?
I would pick the 10 or so that I actually use, and get rid of the rest.
Organize the top 15 of them using any kind of screwdriver organizer you like maybe tool grid or ernst and then “organize” the rest into a Rubbermaid bin in the corner of the garage. Any screwdrivers you haven’t dug out of the bin in the next year get sold or donated

Who makes those partitions?I partitioned mine.
Drivers are organized by tip style and size.
I really like this method and find it functional.
Occasionally I have to move something to get what I want, but for the most part I can see everything and its not a big deal. I keep the most used on top anyway.

Looks like standard Lista/Vidmar/Equipto. Most I have seen are gray vs the tan. Edges of the drawers have matching slots to keep them upright.Who makes those partitions?
