A plain 9 digit VFD

While digging through a bin of calculators and spell check thingies at a thrift store, I came across what looked like (At first) an old handheld calculator that made use of a VFD (Vacuum Florescent Display).

I didn't have everything mentioned in the instructable, but I did have files, a torch, hammer, some old nails (Cut square nails from our house, actually), and a section of old rail to use as my anvil. After a few hours worth of work, and much heating, hammering, grinding, filing, and sanding, (Plus a bit of thread wrapping), here's the finished result:

The minisword! All earwigs and earthworms beware!
As you might be able to see, it's a but rough, and the hilt is somewhat crooked from the blade, but for only a few hours of work, I'm quite pleased with the result. I didn't originally intend for it to be curved either, but thanks to my low blacksmithing skills, it turned out that wa…
