Day one:
I started a restore on this vintage 1901 nautical whaling rope knife yesterday after work.
This restore will be done without dismantling the knife.
I started out removing the rust stains in the bone scales around the iron pins on the one scale. I used bathroom mold & mildew stain remover mixed with kitchen cleanser diluted with water. I soaked a sponge in the solution and laid it on top of the scale with the problem for a couple of hours to draw out the rust. Works like a charm. I did a little hand sanding after as the pins will tarnish from the water in the solution.
Next I started on the blade removing the dirt and tarnish.
I used my special formula which contains a mild acid. The rest of the solution is a secret I will not divulge. The bone scales must not touch this solution and must be protected. I use a thick coat of Vaseline then wrap the handles with blue tape followed by plastic wrap. After soaking the blade and bolsters in my solution for 15 minuets and flushing with hot water I dry with compressed air. Next to the belt sander we go. I used a super fine scotch bright belt to remove a couple of small pits that were in the blade. This belt will remove a very small layer of the metal. I was very careful around the makers marks and ended up doing that area by hand. I was also able to get the nicks out of one of the bolsters with the dremel barrel sander bit then gave it a polish with the grease wheel. I also hand engraved the part of the S in Svane Kniv that was missing from ware. I am not much of an engraver but did the best I could. The rest of this project is for another day.
Here are a couple of pic's of this restore in progress.

Day two:
It doesn't look like I got much done today but in actuality I spent most of the afternoon color matching the material to use to fix the chip in the bone scale.
It took a while but I think I got it close.
The fill I used on this patch is a two part clear epoxy.
I usually mix different color paints with the epoxy to get the right shade.
But I couldn't get close to the color of these bone scales with the shades I have.
After messing around with other materials I finally found something that worked out pretty good. I mixed a little Elmer’s wood patch with the epoxy and it matches very close "go figure".
Here are a couple of pictures.
The glue is fast drying but I like to let it dry 24 hours before taking it to a belt sander.
Plus I'm running out of time for the night.

Day three:

Well, this is the finished product.
This is the best I could do with this old knife.
This knifes blade and steel parts must have a tremendous amount of carbon content in them.
The steel for some reason starts to tarnish up over night even if I put a coat of Rem-oil on them.
Since I am going to be using this knife for work purposes in construction, I’ve opted to put a 600 grit matte finish on all the steel and am thinking of forcing a patina for extra protection. If I were to put a high polish finish on the steel, the first time in use the knife will get scratches. The patch on the chipped bone handle came out better than I thought it would. I can’t even tell where the chip was. The makers marks may have lost some of there detail in the cleaning process but they look better than they did. I also did some adjustments to the blade to make it sit properly when closed due to losing a little of the blades edge in the overall process. The only thing left to do is treat the bone with some mineral oil, force the patina and put an edge on the blade and she is good to go.
This knife cost me less than 5 bucks so the first time I use it for something productive I think I’ll get more than my moneys worth.

Looks very nice! Many folks don't realize the time invested in matching the color of the patch to the color of the handle material. A lot of care must be taken to match the color, it usually takes me 3-4 times longer to match the color than it does to actually fit the patch. It looks like you matched the color of that patch beautifully!

It doesn't usually work that way for me.
Sometimes the patch will dry lighter or darker.
But because this whale bone has so many different colors in it you can get away with it.
I guess I just got lucky this time.
The steel on this knife has tarnished up so much over the last couple of days that I decided to help it along. I got it soaking in my potato salad solution for a few hours. Sould give it that dark gray patina which will help it from rusting. I plan on using and abusing this one.

Would you be interested in selling it? Are these scales original?

Sorry, this ones mine.
I put too much work into it to let it go now.
Everything on this knife is original.
I just gave her a proper conservation & stabilization.
The knife hopefully if cared for properly will last another 110 years.
I don't think you would pay what I would now ask for this knife after putting in all this labor if I were to sell it anyway.

There is a good product for preventing rust that was developed for the gun industry.
It is called Eezox.

I ran in to some guys at the OKCA show this last weekend who use it on knives also.
I learned about it from a customer who is a gun collector.
I have used it with great results.

BTW, nice work and a nice save of an old knife!

Thanks for the info Orvet,

But I like doing things the old school way.
My Uncle was an extreme fisherman.
I remember when I was a Kid watching him soak his fishing knives in German potato salad.
Sounds a little weird I know but it actually works on High carbon steel blades.
It also gives the blade a dark gray black patina. Sort of an antiquing.
After soaking them he would wipe them down with light weight oil.
Plus when you make the salad you can eat some of it before you use it on your blades.
I inherited one of his steel fishing rods & reel and an old filet knife after he past on.
The knife & rod has been hanging on my wall for years and I occasionally use them and after use I just wipe them down with oil and the knife & rod show no sign of rust.
