I have small gun vault with no guns and 18 drawers per 3 units, stacked up that were to be screwed on the side of fancy tool chests....I only have a couple of big non-folders , so the drawers are lined with the thin foam that goes in tool cabinet drawers and the knives are grouped in similar models. Models and descriptions are printed on strips of paper and taped to front of drawer.
I know there are many here with more than a shoe box of knifes, do you ever think about 'Bad' things or just handy storage.
Bad things being theft, fire or flood. OK, so you lock it up, screw it down , lock the lock for theft. What about fire or flood. Hopefully, you are out of the flood plain, if not you put them on the second floor or just hope. But fire, you can actually do something about that. If you build something to put your knives in, line it with fire rated sheetrock or drywall. (Don't use imported drywall)
That is what lots of gun vault makers use. Depending on the number and width of layers you get increasing temp and time of flame contact control. I retro fitted my cheap, non-fire resistant gun case with 3/4 " fire rated drywall. I guess I have a good 20 to 30 minutes to knock the fire down in that area...or the little city department does. In dire straights the vault is situated where a hose directed thru a outside window with directly hit vault. I thought about putting the case on the outside wall then if the other end of the house was totally engulfed and I hear no sirens on the way, I could cut power and chainsaw around the vault, throw a chain over it and jerk it away with vehicle.....
I hear you laughing now, but how many of you plan for other emergencies....how many think about surviving a tornado, power outage or intruder attack......thinking about saving your hard won traditional knives is no different. Many slipjoints have scale material that will survive some heat and my old black Bucks plastic scale materials a little less so, and some other older knives not so much either. But gain some time by planning and building for heat. You may need them to sell to get back on your feet.
So given the chance to plan, think about fire, line your boxes, line your chests, line a closet. Give yourself at least 30 extra minutes for the fire guys to knock down the flame and heat. If your home you can point out the gun and knife area to the hose men, tell them don't worry about the dishes or furniture.........
