Most photos show files just tossed into a drawer slapping around with other tools or files. I was taught that a file was to be protected from this type storage. My files each have a sheath had from clear flexible rubber hose.
Storing files is tricky, because condensing is good, but contact is bad.
I recently found a fun way to store needle files.
I purchased the colorful board on my next trip to the store, where all games are $.50 each. Thankfully, it has slightly larger holes that fit the Dremel bits. Cribbage reminds me of summers at the cabins with family.
The little-file drawer isn't as crowded now. I seem to reach for the black handled one the most. That's an old pan lid knob.
There's another deep-storage drawer below that.
I paid a buck or two for this old board full of holes. It works well for pointy-tipped files and handle-less ones, but it's a little overcrowded. The grün handled rat-tail on the right was my most-recent find. It's a repurposed kitchen utensil handle.
(I collllect those too).
Others dangle by their handles in an overcrowded slotted board I made myownself.
I need to go through and cull out the duller ones, one of these days.
