My friend found this rare screwdriver in the steel waste at the recycling station. It was dirty, rusty and from its look you can tell that it had a hard life. It was bent in all directions and was used for more than just tighten and loosen screws. I really liked the design of it, specially because of the look of the handle. I've never done woodworking before in my life, that's why I decided to challenge myself and restore this beauty. As i have no clue when it comes to wood, I had to do some research first.I found out that ash wood is very common for handles in general, that's why I decided to go with it. The second thought i had after deciding to restore it was that I'm not going to use any glue to fix the handles. I'm going to use handmade rivets, I've never done that before either. I was really happy with the result, it came out exactly how I wanted.
I hope you like my work and the video.
