I started using both 1x2 wood and 1 1/2-2" PVC pipe to make knife supports when I run out of room in the safe.
I started with the wood but tried the PVC as it is inert so it won't hold moisture - but rust has never been a problem with either.
Cut V notch about every 1 1/2", place in middle of shelf, run knives on both sides with plenty of clearance for my hands to remove chosen blade.
Easily tripled my storage space - more space, more knives LOL
edit: just re-read your post and realized you wanted edge up storage...
