That's a cool razor, I'll have to get me one of them.

By the way, it is interesting to note that on many (not all) hollow ground razors, there is a slight bulge present just before the bevel:



My guess is that the bellied design was incorporated into the industry standard to fix what Korn described in his patent abstract as the "vibratory character of the edge" present in the earlier hollow ground razors. I pulled out my full hollows: the Klaas, a Mella High Class and a C-Mon Blackie all presented the pre-bevel bulge. The new TI that I have does not have this feature, nor does my early Filharmonica Doble Temple 14.

Interesting, though I'm sure they were producing bellys before this patent. My M&W's have the tell-tale sign of pre-Madrid Accord production (1891): no country of origin stamp.

Now that I think about it my Puma 91 may be bellied as well. I should go check...

I'm sure there were & IIRC "Hamburg Grind" was another name for them.

If I'm not mistaken, "Double Concave" and "Double Hollow" were also used.

My sharpest razor is a Mappin & Webb wedge blade. So sharp my skin won't allow daily use.

Yet. still it is no name, no brand:-(

well i only have once razor that is shave ready so its a pretty easy choice for me. its a richards & conover ,kansas city 5/8 full hollow. i get good shaves from it but i think i am the variable. my technique is not exactly flawless lol but i enjoy the learning process.
