In a few days I must receive these blades blanks from Germany.
I don't know the history of these blades. Your opinion? And I need your advice what to do with them, to grind and to hone or only to hone?

Dorko's are good shavers but those blades look to have some serious pitting. Start by scrapping the rust off with a single edge disposable razor blade so you can see what's under the rust. Being hollow ground there isn't going to be much metal you can grind off before the blade gets too thin. If you do grind be sure to have safety glasses and a face shield. A leather apron may be a good idea also. Protect yourself from flying metal should the blade break during grinding. Also be aware that blades can launch off the grinding wheels if you are careless even for an instant.
Good luck.
Thanks for advice.Quote:

But if I'll decide to grind. I'll do this on my workplace(factory) on the grinding machine tool.
Looks like a lot of hand sanding and maybe some time on the buffer. You will get some good shavers though,but due to the thinness of the blade you may not be able to remove all pitting. Surely worth a try, and you may end up with some real beauties.
Simple. Send one my way! I like their grindQuote:

I agree they look like blanks just prior or right after heat treatment. I would first check the blades to see how they react to a file to see if thy have been in fact heat treated. They may be ready for final grinding.Quote:

So, I received blades and the first result isn't bad ...I think.:)
I hope the end of the work will good.
Looks like that one is ready for some quality time with the hones. Screw grinding it, pin it, hone'r up and shave away.
Looks like there is some pitting really close to the edge... I dont know how well it will hold up with honing. Usually, pitting on/near the edge spells doom.
It may be possible to try honing with a few pieces of tape to increase the bevel angle and keep the edge from reaching the pitting... But I am no expert, so others may chime in.
It's not pitting. But this seam is more interesting for me.
Not sure what to make of them. Usually one would need wheels to get blanks properly ground, but they appear to be frame backs.
However the blades appear to be a millimeter or more in thickness, so wheels of the proper sizes could get them ground… 1 and ˝ inch for the hollow and maybe 8 inch for the edge.
As they are now, if you simply sand and then hone the result will be very large bevels (not to mention flattening of the spine unless taped).
This is an interesting find… please let us know what you do... and the results.
Here the result. Blade is ready. I must receive the same pin. And the razor would fully ready.
Unfortunately on one edge there was deep rust, but it will not affect quality of the razor, unless on appearance.
The end of my humble work with Dorko at this time.:)
Very nice Alex
I did not envision such a good result when I saw the first photo you posted!
But I have left the most "tasty" on the next time, 7/8 blade.:)
Awesome Alex! Would you be so kind as to post what grit sizes you used to achieve the results for aspiring restorers?
Did you handsand majority of them or dremel/sander?
Did you use 1/16 pins from microfasteners as well?
Again very inspiring
Thanks,
Ivan
Yeah, I'll take it. Thankyouverymuch. ;)Quote:

For polishing I used Dremel and grinder.
It's simple Dovo pin.

May be, may be.:)
I think to visit Germany in spring...
Excellent. Beer is on me. :)Quote:
