Thumb notch

I saw a new razor with a thumb notch. It sort of looks nice, but I have never seen this before. Does anybody have such a razor?

Attachment 226596Yes, and it's one of my favorite in the hand. Tc

Thumb notches are aces to shave with and Jokers to strop.

Thumb notches razor are somewhat common, but its brother the double thumb notch is not so.

I suspect that some of them were added by the same guys that did the regrinding of old Sheffield blades. I agree with WW243, they're great the shave with and awkward to strop.
