Maximum Hollow Kamisori

Hello,

i would like to show you a kamisori style razor i made for a customer. Needs some more finish but the focus on this Razor was the maximum hollow ground i could do on the beltgrinder. The customer wanted to try the grind on a simple not so expensive Razor and order a more complex design if he likes it.
I am very happy how the grind did turn out, and wanted to share this.

Nicely done on the belly. How is the flex in that blade? Impressively thin, I must say :tu

Nice job grinding it looks great.

Charlie

Now thats a fine line!! excellent!!

Ray

Wow! That is some fine grinding. Well done.

Ulrik,

I've come back and looked at your images several times, and the thinness and symmetry of the blade fascinate me. Well Done!! :D

Regards,

Howard :)

I think the idea of a kamisori is the shape and the harder material on the stamped side with the nonstamped side being iron. but other than that it's an awesome looking fixed blade razor I'd even buy a fixed blade razor if I had the extra money right now

as others have said, very nice grinding, thin and symmetrical, congrats

That Is amazing,all my best shavers (palmeras) are belly ground,I wish more makers made them,Great work Ulrik

The grinding is very impressive, great work!

Man that looks awesome!

Is that slightly thicker part in the middle of the blade for added stability? I love the way it looks.

Thank you all for your kind words.

@str8fencer: Thank you! The blade is very flexible, even a soft touch makes it flex from the edge to the belly.

@Swerve: You are right, this is not a real kamisori. Fixed straight surely is the better term.

@ZeroCool: Thank you. Yes, the thicker part (belly) gives a bit more stability. Without it the blade would be to flexible.

cheers,
Ulrik

Great griding skils and geautiful razor.
Do you have some WIP pictures? What did you use for grinding that profile?

Thank you.

Unfortunately i did not take any wip pictures. Maybe i take some next time i make such a grind.

To create such a profile you need at least two different contact wheel sizes. The more different sizes, the thiner the final grind can be made.
I started with a 20cm Wheel and made a grind to nearly zero at the edge. It is important to have a perfect grind at this point, any mistake will make the rest much more difficult.
Next is a 10cm wheel with a hard coating that is very aggressive. With this one i grind till i nearly reach the edge. Then i change to a soft 10cm wheel an grind the rest exactly till i reach the edge. The blade is now hollow ground but hasnt the belly yet.
To achieve this i change to a 5cm wheel. I start grinding at the spine and often change the side to get it symmetrical. This needs to be done till both grinds nearly match in the middle of the blade.

I hope this is quite understandable ;-)

cheers,
Ulrik

Thank you very much for your instructions. Do you have some jig or you grind free hand?

No problem.

I do the grinding free hand.

cheers,
Ulrik

WOW! Great skils you have!

Gosh that must sing when shaving.
Very thin and very impressive work.
Thank you for sharing your skills.

One more question.... Did you hadrening blade before grinding or somewere in the middle of this procedure?

I always do the rough grinding with the 20cm wheel before hardening. But i leave about 0,5mm at the edge.
The rest is done after hardening.

I thought so. Thanks!

Holy Snappin' Ducks. That grind is incredible. :bow Sensational work.

Stu

Yikes, any thinner and you wouldn't be able to see it. I bet that takes a lot of time and some very fine belts. Probably some water for insurance ? Your skill level at grinding is to be looked up to for sure. That is a nice razor and can hardly wait to see the next 1.

impresive grinding skills and blade geometry.

I love the way it looks, excellent work.:tu
