Too many vegetarians in India to have a wide spectrum of knives. Not a fan of Santoku but Nakiri and short Gyuto are good choices. Diamond plate(s) may help meet your weight and cube requirements. And Maxim will ship knives, stones, just about anywhere.
BTW, $300 nakiri on b/s/t for $200 right now. (Hope shameless plugs ok)
Older and wider.
I hear and I forget. I see and I remember. I do and I understand.
Watching episode two of 'Rick Stein's India' where he uses what he calls 'my 40-rupee Indian knife' which to me looks like a KU-clad carbon nakiri with a curved blue plastic handle.
Got that Ealy Nakiri, suggestions on Santoku/Gyuto welcome!
For sharpening, you can get a whole lot of wet-dry for not much cash and it won't weigh much, but I'd recommend the Norton 1k/4k combo stone. It's big (8x3), got good grit combo, and not a lot of money.
Seriously, 3 knives and a stone for about one-half your intended budget - who says 12 step programs don't work!
Oh, here we go...
For the santoku I would check out maksim's zensho line at jns.
I knew about bonti's but squatting on my heels with that big curved blade between my legs isn't something I'm really interested in doing. If you look close at that photo there also seem to be a large number of other types of knives behind the bonti's. Thanks for the photo Seb.
