How do you tell? This blade looks pretty old, but it also has some waviness/dimpling that I haven't seen. Almost like it was hammered by hand. Nearly impossible to capture in photos, but I tried.
Thank you, Sir! That is good info to know.First photo sure looks like someone hollowed it after the fact.
End shot looks like they did a decent job of it.
So long as the temper is still good - no worries.
I don't think it's a regrind.
Rogers had sort of a signature transition point on their blades with that shoulder less grind, and yours has it.
Rogers blades with typical shoulders and/or stabilizers, or the wedgier blades, did not have that transition point.
Of course, there are always outliers and exceptions. But, I've owned many of them and when I looked at your blade that's the first thing I look for.
The other thing is that when the old Sheffields were re-ground, they were usually done in lots by perhaps not the best artisans. Many times you will find the tang stamp has been compromised. Yours is intact and the lines of the grind match what i remember from other shoulderless Rogers blades.
Lastly, the deep pitting, less common on reground blades. Not unheard of but it's another data point to consider.
If it was mine, I'd consider it to be original.
The 'imperfect' grinding you see is a trademark of sheffield razors, esp pre 1890s blades. Not an indicator of 'regrind'.View attachment 1084778
My opinion is hone er' up and give it a shave and see....could be considered an ugly ducking of the bunch.
Ugly??? Who you calling ugly, Mister? Oh, you must be talking about my older brother...
