Extracting the fibre
The culm harvested from the forest or farm is cut at an angle to facilitate easy felling. Now the kathi (knife) is pressed hard in the centre of the bamboo so that it enters and then pressed even harder to make it stick there. The Kathi is moved ahead, backed by appropriately hard/soft strokes to force it beyond the first few nodes. Then the bamboo is put on the ground and pulled apart with hand. Kathi is now used only at the nodes where mere pulling apart would not suffice to tear the halves. The splits are cut into desired node lengths to splice them into fine silvers.
