Other blades items. Khukris, bayonets, etc.
I do have a few vintage computers, not enough to call it a serious collection though. Timex, Aquarius, Commodore, early IBM, early Compaq (including the first non-IBM computer to be PC-compatible), Sun, Atari, Kaypro, Apple, Tandy, Texas Instruments....
There is lots of other 'stuff' around here related to various hobbies, but nothing specifically for collecting. Photography, guitars, gold pans, mountain bike, backpacks and hiking gear, fishing gear, motorcycle, convertible, pickup truck... Just regular stuff.
