Vintage Cordless Knife Cutter Restoration | HITACHI CK 12D

I found this tool from Japan recycling shop in my city. It is an old model cordless knife cutter made by Hitachi, Japan. The tool is working fine except for the battery. I convert the Nicd battery to a Li-ion battery. I use 6 cells of 18650 and BMS 3S40A to build a new Li-ion battery pack 12.6V 6Ah.

Very interesting, I have never seen a tool like that.

[@tomilipin]

Yeah, me neither and I'm wondering what it's capable of. I can't be a tool just for cutting cardboard.
