Is there any cultural, geographical or temporal distinction between the pihas with a tip that angles towards the edge, and those that curve towards the spine? I noticed this in a number of pieces and I am wondering whether the backwards sweep is due to the blade having been broken.

For comparisons, I'm adding a picture from Oriental-Arms. In this example the sheath follows the same curvature, possibly indicating it was original.
