Preheat the oven to 425 degrees. Combine the flour, baking powder, baking soda and salt in a mixing bowl. Stir with a fork to blend and mix well. Add the butter and, using you fingers as a pastry blender, work the butter and flour together until the mixture looks like irregular crumbs. Add the buttermilk and the chives. Mix only until the dry ingredients are moistened. Gather the dough into a ball, pressing it to hold together and turn it onto a lightly floured surface. Knead lightly about dozen times. Pat the dough into a circle, keeping it about half to 2 cm thick. Use a 5 cm cookie cutter to cut rounds and place on a baking sheet. Bake about 10 minutes, or until the tops are lightly browned. Serve warm.
