Tom19176 is correct. Keep your knife collection locked up and out of sight of any visitors to your home. A safe or a large lockable steel box would be your best bet. I use a large steel Greenlee job site box (locks with two padlocks) as both a small arms locker for my knives, firearms and ammunition, as well as personal papers and petty cash that I also wish to keep secure. Greenlee and similar boxes come in different sizes. They can be had for $300 or less at Home Depot, Lowes and similar stores.
