Both pairs of my shears are coated with a light spray of WD and then vacuumed sealed with a regular old Food Savor....and they both still are 100% sealed and in brand new condition as far as I can see., If ever needed, all I need to do is put the handle end on the heel of one hand and push forward and they will push right through the seal-a-meal bag to then be free and available. I do have wrist lanyards pre-attached so once they are free of the sealed bag I can secure.
I have never yet needed to use either pair of my shears...but feel better knowing they are there and will function as needed, if needed. Fingers crossed...
