A cabinet with vertical dividers - 1/4" panels set an inch or 2 apart with scoop on the leading edge. I don't think a folded blade will deform sitting on edge. If that is a concern space 1/2" thick panels further apart and set the blade(s) on hooks mounted to the panels. All will be behind a closed door, with maybe an open shelf or drawer under the blade shelf for accessories.
