pocketknife renovation

[Jokke]

Hi,

an old friend asked, if I could make a new blade for his old pocket knife with a worndown blade, it needed some restoration, so I got an idea,

and since I had fun making it, I took some pics to show them here

this is how it came to me:

so I found a piece of damasc for it.

 

It is damascus with 500 layers, made from 1.2510 and 75Ni8 by my friend Micha Schick.

I cut out a piece and started with shaping the blade. I used files and worked slowly, which was easy since the damasc was very soft super annealed, quite astonishing for me, since I normally hotwork the steel I use, nearly to endform. It was easier than I first thought...

My first pocket knife blade ever...

so I kept on filing with different files to get the blade right

so it took on the right dimensions

and here you can see how worndown the old blade was

(in my eyes no wonder, because of the steel, stainless,

a bit too soft to hold a good edge long

had to see to it that the thickness was right,too

So it took some evenings, since I worked rather slowly,

but then the blade was ready for hardening,

this is how it come out of 830°C and into lukewarm oil:

 

 

and the parts to be put back together

I wondered if I did everything right, you can see that the main pin was all that needed to be removed to get the old blade out and the new one in. You need to take a good look, to see from which side the pin is more narrow and then to slowly force it out. Back into the holes carefully the same way back...

so I tried the fittings:

needed some adjustments and more filing, which was quite hard on the hardened blade and the steelspring on the back

I sharpened the blade on a belgian waterstone, gave it a shaving sharp edge,

the steel is about 60 -61 HRC after an hour in the oven with 170°C

had to see to it, that is was tight and smooth, too

there is no glue on the brass fittings, normally you would simply use a small hammer to flatten the pin on both ends. That would give the strength to hold it all together tight

if you wonder about the loose brass fittings, Axel will want to fix them by himself

I did not want to hammer on the sides to fasten the bronze pin

so this is it now

 

so I keep it in my pocket for a while, bevore I send it back to Axel,

just for the feeling of it

it feels good, I must admit and it is fun to see it done

by the way, it is an old piece from G.Grafrath, Solingen Germany

 

hope ye had fun looking

best seasons greetings from Germany!
