Note that the seller for this item is in the UK; for some reason, it seems like it's been raining cute old khuks in these parts lately - I picked up two in the space of ten days for a combined outlay of under $50 US; poverty compelled me to pass up another two, priced at around $50 each. All four were early-mid twentieth century, wood handles, steel bolsters; the 2 I managed to buy both proved on testing to have decently hard edges, and AFAICT are the real deal rather than Indian or tourist stuff. These were at small local antique/junk shops, not specialist dealers.
Also saw what I believe was a genuine kothimoda, similar to a couple of those illustrated in the Powell collection; but it was priced at 100 UK pounds, therefore well outside my price range.
