The markets in Cambodia are very extensive. Selling everything you can imagine (fruit, vegetables, fish, meat, etc.). All of these product require cutting and chopping. All the vendors are not only selling their products, but they are cutting up more to sell all the time. I came around a corner and hidden behind a tent was a knife sharpener. That is all he did and he did it all day long for all the vendors so they had sharp knifes. He paused long enough for me to grab a quick photo as he took a break.
