In today’s post I am restoring old broken pocket knife. I found markings on the blade Gust.Haker Solingen. Pocket knife is rusted and hard to open. Also has a smaller broken blade.
My first idea was to replace the blade with spare ones, but after finding markings on the smaller blade as well I decided to keep it and shape it a bit…

This one was not so hard to take it apart. I hammered all pins out on small anvil. Furthermore I checked all pieces for damage and imperfections. Other than rust all looks good.
Vinegar bath and sanding
To get rust easier from metal parts I placed them in a vinegar bath for 12 hours. While waiting I jumped on covers to sand down and wax them. It was quite pleasant surprise to see them as new.
After finishing both covers I pull out metal parts from vinegar and washed them with water. After that I brushed them with steel brush.
To be efficient I used a steel brush wheel mounted on hand cranked grinder and cleaned all the parts carefully. This was a great example to do it fast, definitely efficient and with good result.
So, next step was sanding. For sanding I used sandpaper 120 > 240 > 400 and 800 grit to get nice smooth finish. As a result hand sanding is definitely a time and energy consumer. So, If you plan of doing similar projects please be aware.
Polishing and assembling the old broken pocket knife
Finally is time to get some shine effect to metal parts. For that I will be using same hand cranked grinder, but this time with a polishing wheel. I applied polishing paste from tube. It works good for hand polishing or with this hand cranked grinder.
The funny moment was when I burned myself with a small blade on polishing wheel. Lesson learned here. Next time I need to use gloves, because while polishing it can create a lot of heat from traction…
Finally all parts in place and I am ready to put it together. To assemble this old broken pocket knife I used new brass pins. IF you don’t know where to find them I suggest checking out this two links:

Assembling didn’t went smooth. Even though I haven’t removed any material from spring or blades area around spring I got a knife with very weak spring. So I disassembled the pocket knife again and adjusted the spring itself. That helped a lot to get better spring effect. After that I successfully assembled the knife and hammered all pins in place.
