I was avoiding this old knife to restore for a while now because it has a broken tip. Finally, I did the old KKS knife with a broken tip restoration video. The whole restoration process went smoothly. I even had a chance to use a recently restored hand drill press to make a brass disc for this old knife. As a result of this restoration I tried to keep the knife in a vintage look with that blacksmith charm…

I started by disassembling the knife. Usually there is a small washer which holds the blade in place, but with this one that was not the case. It was glued with a not very strong agent.

It took me a while to scrape that filling agent out and release the blade. After pulling out the blade I managed to separate bolster as well. Here is how it looks after disassembling.

Vinegar bath, cleaning, sanding…

Since the knife is disassembled I placed the blade and bolster in the vinegar bath for 12 hours. For a moment I thought the bolster was made out of copper, but I was wrong. It is brass.  

Always after vinegar bath the metal changes color. Bolster it looks like copper, but it is actually brass.

The next step is to wipe the blade and brush it with a steel brush wheel mounted on a hand cranked grinder. I managed to get the surface clean enough to be able to proceed with the restoration. So the next step was to mark out the line for the blade’s tip. In that way I could grind some material and reshape the damage. So don’t look broken as before.

It was nice to see the hand cranked grinder in action. After a few minutes I got a nice ending blade.

I will stop here with grinding, even though I marked much more.

After that I started using file and I removed some material from the blade. I did that on both sides. This was not very difficult since the blade is made out of laminated steel. This means that the outer layer is made out of soft steel and in the middle is very hard steel.   

Here I finished with a file. I removed enough of materijal to start sanding.

Finally to finish the blade I did sanding with wet sandpaper. I started from 120 grit and finished with 800 grit. In between I sanded the handle as well. I got a really smooth finish with 800 grit.

Ready for assembling

This was a moment where I become excited. Final step before I can say I restored one more.

Here I was ready to start assembling the knife.

Assembling was really simple, just stacking pieces in order as I removed them previously. I used just a little glue to secure the brass disk piece that I made (check out the video above) and the blade itself.

  1. Nice restoration. Trusty knife.
    Have you ever considered a pedal (pulleys and belts) system for your grinder? You will have both hands free. Just an idea.

  2. Hey Boris
    This is exactly what i mean Last time
    You give Tool , knives and other Things the Soul back.
    The Brass Tip give the handle the perfekt Touch.
    👍👍👍👍

  3. Man, when you started crocheting the handle. I flinched !!! Sadist dentist 90lvl! =)))))))

  4. very nice job. I love the fact that there’s a knot in the handle as it really adds character to it.

  5. You did a great job as usual and put a lot effort in this restoration. Just a little tip if you don’t mind… The tip of the knife in my opinion has to be more sharp, the rest is perfect!

  6. stoooop
    never cut sandpaper with a knife you just sharpened
    I have seen that before in your vids but thought(and hoped) that I just saw it wrong.
    turns out you realy do that.
    pls dont
    <3

  7. Look for an old fashioned treadle sewing machine. It has a table and a foot powered treadle that usually turns a sewing machine. Remove the sewing machine and put your grinder on it and it will turn it much faster and not use any power other than you. You’ll like it

  8. Love your videos, but How do you find so many knifes? I always looking for some knife to make a restoration video but I never find one. Some advice? Perfect job by the way.

  9. I ĺike that little knife! Just looks like he belongs on his own! Nice fix

  10. What I like best in your videos is the saving and restoration of the original handles. There are many people around cracking up the old wooden handles and replacing them with newly made ones. I would always prefer reusing old wooden parts, if possible. Thanks again for another great video !

  11. Very nice and pleasant to watch. But never use your hand as a hammer. Just my 2 cents of good advice.

  12. Good job, friend. You have skillful hands. Take care of them. When I saw you stick a wooden handle onto the shank of a knife, my heart sank. I have a friend with whom I once worked. He used the same method to put a wooden handle on the rasp shank. The handle split into two halves, and he pierced his arm with the shank. The spectacle, I must say, is not a pleasant one. Of course, I myself do not always follow safety precautions at work, but it was this moment that made me shudder. )))
    I wish you creative success and health.

  13. Hi Boris, good stuff! 🙂👍
    The vinegar bath worked nicely and you did a nice job on the knife tip.
    And the hand milling was a nice touch 🙃
    Nice restoration mate!
