Boti

Boti is a cutting instrument, most prevalent in Bengal, a region in the eastern South Asia which is now divided between the Indian states of West Bengal, Tripura, and Barak Valley of Assam and the independent country of Bangladesh.

Boti is a long curved blade and cut on a platform held down by foot, both hands are used to hold whatever is being cut and move it against the blade. This is quite unlike using a knife; the sharper side faces the user. The method gives excellent control over the cutting process, and can be used to cut anything from tiny shrimp to large pumpkins.
