u/Dry_Schedule_7520

The year the Nanbu Jukan Railway in Japan was scheduled to be discontinued, I filmed a documentary about its railbus for a commercial video package.

At the time, one of the people involved in maintaining the railbus gave me these railroad spikes as a keepsake.

The photograph and ticket were included as extras with the commercially released video.

Looking at these again brings back many memories.

NEPROS' neXT series.

Not many other products have been released in the neXT series so far.

Personally, I would love to see KTC combine the PROFIT series and the neXT series into a new “PROFIT neXT” series.

The “3S” engraving indicates September 2023 as the manufacturing date.

I found this unusual screwdriver at a Japanese used tool shop.

I believe it is probably an older PB-SWISS-TOOLS product, but I haven't been able to identify the model number.

The blade can be adjusted by sliding the cover on the shaft, changing the width and thickness of the tip.

Does anyone recognize this screwdriver or know its model number or approximate age?

Any information would be appreciated.

Two old Stanley Proto Industrial Tools with very different histories.

The one on the left was used as a keychain for about 20 years. The other was heavily rusted when I found it, so I cleaned it up and restored it.

I came across this at a second-hand tool shop vintage hand-operated hair clipper at a second-hand tool shop.

It has a finger ring on the back and a scissors-like operating mechanism. The blade is stamped “SPECIAL CONDOR – MADE FOR BARBER.”

I’m always fascinated by the craftsmanship and mechanical ingenuity found in old hand-operated tools.
