Tackle boxes in the original boxes for the ones not being used. The Users are in various places including my maintenance area drying after being treated overnight. The old kind of tackle boxes which don't have the plastic slide in boxes, though those have their uses as well. Loose knives, sharpening goods, tools, stuff like that.
Larger boxes, and fixed blades need larger spaces but the needs are similar. Stout, water proof, and with a handle for easy carry as some of the tackle boxes even with folders can easily top 50-60 lbs when packed in properly. Fixed blades in boxes need a suitcase. I tried an army steel box but that made the overall package way too heavy and bulky to be practical. In an emergency I wouldn't want to leave behind my Spyderco Bushcraft, My old western 49, My marbles and blackjacks in 52100 and A2, my Fehrman in 3V, as well as my Seki Cut made HSEK 9 inch, Micarta knife in M2 steel ( according to the son of the owner or manager of the company who had to research it for me. Sal had stated he remembered it as high speed, and he was right. Another knife like the Western 49 ( pre 1960 sharon steel what would later be known as carbon V, amongst other names) that took me over a decade to get. The Gerber Sportsman 2 in Vascowear took me over 20 years to get.
I could save the best ( or most important to me) with 1 tackle box or briefcase plus 1 suitcase. The flip side of the coin is I could loose some irreplaceable knives just as easily with the loss of two packages.
