Hello folks! I need some help.

A friend of mine picked up these knives from a flea market in Japan awhile back and forgot about them. He passed them to me to see if I could restore and sharpen them.

I'm currently working on the right most knife as it is possibly the easier right now.

My questions are:

1. How do I remove the heavy rust? I've been able to BKF and remove most of the rust via the rough side of a sponge, but there's still a few rough patches (See pic 3)

2. How do I remove the (I think) stains? Not entirely sure if it's considered rust since it feels smooth after scrubbing, so I assume it's stains due to said rust.

3. The Nakiri's handle is kinda leaving black residue when I hold it. Almost like charcoal. Does it require a handle change? Or can it be saved?

- Additional notes: I have sandpaper, but no access to any heavy machinery or a belt

I'll work on these knives over the next few weeks, so all advice is appreciated!

Hello folks! I need some advice to repair this chair. It's held together by some dowels which I have purchased, but upon closer inspection, there's a pin/nail of sorts that was hammered in.

I can't seem to see from which side, and how to remove it, since it's stopping me from putting in a new dowl, and removing bits of the old one (not pictured)

All help is greatly appreciated!
