Nameste Suraj,
Welcome to the forum. I'm a new member myself and trying to get acquainted.
I was in India a year ago and I made it to the Western Ghats in Kerala, which is fairly close to you, but I did not get to Bangalore. In the northern part of the country I saw a lot of knifemaking and I brought back a few Damascus blades to finish out. I haven't gotten to that yet.
I was also fortunate enough to run across an old scissor smith who was hand forging his wares and sharpening them on a foot turned stone wheel. I bought one for just a few rupees. It's probably my favorite thing from the trip. There seem to be a lot of people using sewing shears for clothing there and a lot of his business was just sharpening shears for the ladies.
I will be curious to see what you are up to and how your knife making adventures compare with my own. India is a different world. By the way, I'm in Iowa, USA.
Cheers,
Cameron
