Extreme bellied hollow ground blade

Hello,

I have recently finished this blade for a customer and wanted to share some photos of it. At the moment it is the thinnest blade I have ever ground. And I dont think I will ever make a thinner blade because the edge would just fall apart ;-)
It´s a bellied full hollow with the belly being 0,4mm thick and the thinnest part being only aprox. 0,04mm thick. These measures are calculated from a very enlarged photo because measuring is difficult at such sizes.

Here are the photos:

I. Want. Bad.

Superb grinding Ulrik!!

Wow, what a beauty... and I assume not easily done... I had seen a 'blue print' (just a wall decoration picture) you could buy with an edge like this on Etsy, and thought it was quite interesting and unique. Nice to see an actual blade with this edge to it. Very fascinating to see. Thank you for sharing.

P.s. Don't drop that beauty on its toe.

Phew! What a grind!!

:dropjaw: Phenomenal grind!

Amazing job.

I can't imagine how difficult that must have been. Outstanding!

Holy Snopes, that is unreal. Beautiful work, lucky fella getting that.

Nice!

Nice work. Love the vintage bellied hollows I have.

Bob

Wow!
Thank you all for your kind words. I am glad that you like this grind so much.
It is indeed a difficult grind and one has to pay a lot of attention not to grind through the blade ;-)

Since you liked the photos, here is one more showing some more bellied full hollows I have recently made. The first is the one from Post#1.

Really stunning work. It looks amazing I have no doubt that the recipient of it will be thrilled.

That is some beautiful grinding, bet they sing like a canary :chapeau

Beautiful grinds Ulrik. That's my favorite grind also.

My goodness...that is thin!
Looks like you have been given "the magic touch."

Pete <:-}

Beautiful, and incredible.

You sir have some exceptional skills!!

Thank you all for your kind words!

Phenomenal work! Your razors are consistently at the 'top of the pile' of any of the newly made razors that I have seen... Just unbelievable craftsmanship!

Impressive

Thank you for your kind words!

I have recently tried to go a step further and to make an extra full hollow bellied grind.
To achieve this I have added one more grinding radius which results in a higher placed and thinner belly. The blade get´s even more flexible but is still not collapsing.

:dropjaw: that really is an invisible edge

No idea what these bellied razors shave like, but it certainly looks cool in the pictures.
Nice work.

That’s some craftsmanship! How in the world did that not just grind right through?

It can happen that I grind through, but not very often ;-) After some hundrets of razors with such a grind you get a feeling for it.

This grind is very close to a "normal" fullhollow. The belly has not such an impact on the shaving behaviour. The most important parts are the thinnest part of the hollow grind which defines the overall flexibility and the last 1-3mm down to the edge. This part defines the micro flexibility torwards the skin and the whiskers

Here is a photo showing the two areas:

But normaly any proper fullhollow razor has at least a very subtle belly because the belly is automatically created while grinding a full hollow.
Often the belly is then reduced in thickness by using flexible grinding wheels and leather weels with a special paste. This process is called "Pließten" in german. It makes the entire blade thinner and the belly is less visible, but it also rounds the edge area a bit. So a non rounded bellied blade is normaly a bit more flexible near the edge.
Here is a sketch showing both grinds compared to a 1/4 hollow grind:

Sir, you have a fantastic skill!
