Lew is absolutely correct about these being from India. They are in the same general class of reproductions as the ones with mosaic MOP and brass inlay on the hilts (see example below). Some are intended for use by Sikhs as kirpan, but many are intended as items to sell as souvenirs to Westerners, etc.
The "Pure Steel" inscription is probably the most common marking on these reproductions.
I've picked up a few of these inexpensively. Some are quite attractive and reasonably well made, although most of the blades would not stand up to much use. Some of the blades have been electroplated.
