There are many regional forms of billhook in India, and as many different names are there are dialects and tribes. Again a problem obtaining information due to the language, but often as English is spoken universally, so not as difficult as, say, for Chinese or Japanese tools.
Up to the end of British rule and the Partition, India was a market for UK made tools, but locally made tools had also been made for centuries. Since WW2 India has developed its own manufacturing industry, and new billhooks are being made for the European export market - some UK 'makers' import tools now - I have even seen some Indian and Pakistani makers offering a full range of Italian leather handled billhooks.
A tea pruning hook, marked T E Thomson, Calcutta - Thomson, established in 1834, were factors, sourcing and importing British goods for the Indian market - this tool is probably Sheffield made.
