Good observation, Lotfy. The heat treatment/hardening would not be made at a later time - highly unlikely without ruining wootz pattern. So better to accept the tempering is original, which is not as evident for the false edge. the question is: can heat treated edge be sharpened/reshaped at a later date while preserving the same color and contrast? I'd think the visually darker contrast would be throughout, not only surface based. so technically it can be. sorry for throwing it into the mix, as this is just a guess.
