Preheat oven to 200 degrees C. Using a blender or food processor, grind oats until fine.
Put the blended oats in a medium bowl and sift in the flour, baking soda and salt. Cut in the butter using a pastry blender or your fingers until the butter lumps are smaller than peas. Stir in the honey and buttermilk to form a stiff dough.
On a lightly floured surface, roll the dough out to 3mm in thickness. Cut into desired shapes with cookie cutters and place biscuits on to ungreased baking trays 2.5cm apart.
Bake for 5 to 7 minutes, or until edges are lightly browned. Remove biscuits from baking trays and allow to cool on wire racks.
