Thread: circa 1810 -1820?

Santa came early for me this year in the form of this find from an antique store. $25.00 and another 20% off for Christmas. No name on the blade. Just 'warranted' on the tang. English maybe? The blade has/had an etching on the show side but it doesn't show up in the pictures. Looks like it was some type of design. No words or letters visible. You can just see the edge of the etched panel in the close up picture. Someone got at it with an abrasive of some sort. What got missed with the sand paper shows it had a high polish. I was guessing c. 1810 - 1820 based on the wedge grind/blade geometry and the scales but I thought etchings came later. The scales are dyed horn with a lead wedge.
Merry Christmas all!
