Thoroughly mix together flour, baking powder, baking soda, and salt in a bowl.

Add cheese and chives and mix thoroughly.

Grate butter into flour mixture, mixing thoroughly with a fork to avoid clumps of butter.

Slowly pour and mix in buttermilk with a spatula until the ingredients begin to clump together and then use hands, pressing the clumps together to form a dough.

Transfer dough to a clean, dry flour coated surface.

With your hands continue to press and even out the dough until it is 1 inch thick.

Fold the dough in half and use pressing technique to return to 1 inch in thickness.

Repeat folding and pressing technique another two times.

Coat skillet or baking sheet with butter or cooking spray.

With a medium cookie cutter push down on the dough to cut out biscuits. Do not twist as you cut.

Once you have cut out as many biscuits as you can, push the balance of the dough together and press into 1 inch thickness and then cut out biscuits again. Do this as many times as you can.

Arrange biscuits so that they are almost touching in your skillet or baking sheet and brush with egg wash.

Place in a preheated oven at 425 and cook until golden.
