Despite all the BBQ tool analysis

JUDL!! I cant resist throwing in my 2cents on this 'item'.
I am inclined to agree with Marc on the 'Victorian' period assessment, but am wondering if this might be a theatrical weapon. It seems that some of the weapons made for 'period' performances were made sturdily, although not necessarily completely accurate. While this sword is made to appear to be a cuphilt rapier, it is clearly not intended to withstand comparison to the authentic examples. It would however, present the desired effect as part of a costume in a performance.
Just speculation on my part. It seems like many of the so called wallhangers or reproductions for gentlemans parlors during Victorian times at least made viable attempt at a degree of authenticity. Many of these were easily passed off as authentic examples by antique dealers in the 20th century to unwary buyers.
Katana, even if this is a Victorian period sword, for whatever purpose, it still clearly has its own story to tell....
All the best,
Jim
