If you have a slew of brass and wood 110’s, they’re hard to sort when they’re laying on the table. My collection covers many brands, materials, colors, and modifications. It doesn’t take me long to find the knife I’m looking for in my 8 holders. I will sometimes make up a couple of holders to do a show and tell. 160 knives are fairly easy to keep track of. The backups are in original boxes in the safe. The less interesting stuff goes in plastic tubs.
