The knives are the danger, not the block. Sheath or wrap every blade individually before you touch the block itself, and this becomes one of the safest packs in the kitchen instead of one of the riskiest.
Pro tip: A rolled dish towel with each knife in its own fold, taped at both ends, is a free and effective substitute for individual blade guards.
Watch out: Never pack loose, unsheathed knives directly into a box; a blade can work through packing paper or cardboard and cut whoever unpacks it.
