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.
