Does anyone have any additional info on these? I can't find anything more about them in any straight razor or blade manufacturer database:

"Ivy straight razor with a pretty leaf tang stamp, which was made in Germany only between 1900 and 1901, by S. Hecht and Son"

and

Theo A. Koch, Marcella style straight razor bone handle, 1913-1917, wells street, chicago

and

Louis Grah & Soehne, Solingen


Any info would be appreciated, thanks
