I have 'inherited' some hex-sided glass/metal display cases from my wife's collections as she out grew the cases. I have fb's in one (Sheaths are elsewhere.) - folders in another. They lock - and are too large/bulky to steal, thus, a lot of broken glass would be necessitated to get at the knives. I know crime is rampant... I mow the grass with a .38 in my pocket... but last month, an even more 'real' tragedy missed me by a block or so - an F3/F4 tornado. My neighbors' devastation was all but complete. Insurance? Sure - but it's just stuff. Enjoy it while you have it. Sure, much of what I have is worn and virtually useless - but I like them. Plus, as I said, my wife 'out grew' the cases. I bought my cases - and, later, her current cases, from collectable type gift stores as they changed 'lines'. My pair were $50 & $75 when I bought them for her. They are made for sales, so they have quartz halogen lighting at the top, with glass intermediate shelves and a mirrored bottom shelf. Her trio of replacement cases are taller. Don't try to buy one new - one of her current cases cost more new than whats in all three of them did combined. Check local collectable/gift stores, if you can find one still open! Sadly, her trio of newer cases was bought when her favorite store closed.
