I like to keep spare blades sharpened up and ready to go so that I can get through a project without stopping to sharpen. For my BU planes, Veritas' nifty plastic storage cases work well, but their cases for BD blades are too short for factory Stanley BD blades. I used a plastic letter/check file folder for a while, knowing I had to figure something out. A plastic desktop file holder provided the inspiration for this blade storage box. The wooden box is 1/2" oak, with saw kerfs cut at 1/2" intervals. I cut the kerfs in the floor and back of the box as one piece to keep the kerfs aligned, and then cut to length. The dividers are cut from 0.08" thick acrylic sheet and shaped by bandsaw and belt sander. An inch or so of glue from a hot glue gun holds the dividers in place. Masking tape ID's the sharpened blades, the ones needing attention have no tape. I have 3 2" blades/chip breakers still in the package. They're too cheap from Stanley not to stock up on them.
