The best way to thin down a blade would be to take off the handle of a Deepeeka, or indeed any other then lock the blade in a bench vice by it's tang. Then with a 4 inch disc angle grinder it only takes a few mins' to thin down the blade thickness, not forgetting to wear good gloves and of course safety goggles.
