Introduction: Old Knife Restoration (Step by Step)

About: I love to make DIY projects with my son

What ?

Restoration of old knife - cleaver.

Why ?
Becaouse it is shame, that somebody threw away such good knife, because we all should be more carefull deciding what is trash and what could be repairde, because it is good to make something from nothing/from trash and because it could be great feeling cuting meat with self restored knife

What woudl be needed:

One rusty knife ;-)

sandpapers (from 80 to 400)

drill or rotary sander


Step 1: Get Rid of Rust

First You need to get rid of rust. This could be done as on the picture with grinder or with vinegar. Just put the knife into vinegar for a night and the rust should be gone but then.. You still need to grind/sand the knife to get rid of bumpy holes made by rust :(

So I decided to use just grinder.

Step 2: Polishing

After first grinding You will get rust free surface but not very smooth. Now You need to sand the knife.

I use for this drill with sandpapers from 80 to 400.


Overheated knife could get soften and will never be so sharp again. So cool it often during work.

Step 3: The Handle

Cleaning the handle is easy. You could do it by hand - it will take a long time, but it isn't bad idea at all. Such way gives better accuracy.

I however used rotary sander - it is faster way :)

The end of the handle was sanded manually.

Remember to sand with sandpapers from 80 to at least 320.

Step 4: Finishing

Now the easiest job to do - putting stain on the handle and sharpening the knife.

You can use any stain but keep in mind that it shouldn't be poisonous for people since the knife will be used in the kitchen.

Step 5: The End

That's all :)

Now You can enjoy Your brand new knife (made from trash). Isn't it great ?
