Protect a biscuit-joiner blade
To use a biscuit joiner for building face frames, you need to change the regular 4-in.-dia. blade to a 2-in.-dia. face-frame blade.
When I switch out one blade for the other, I put the loose blade in a CD case. The case fits both blade sizes and I can drop the encased blade into my biscuit joiner case, where it is protected from dings and damage.
