Preheat oven to 400°F (200°C). Line a baking sheet with parchment paper or a silicone liner.
Stir together the flour, oats, brown sugar, baking powder and salt. Add the butter, and mix with a pastry blender or a fork until the largest pieces of butter are about the size of small peas.
Add the milk and honey, and stir just until a dough forms. Gently stir in the currants and nuts.
Drop the dough by 1/4-cup portions onto the prepared pan, leaving about 2 inches between the scones.
Bake 12 to 15 minutes, or until the scones are golden brown.
