Preheat the oven to 350°F and line a baking sheet with parchment paper.
In a mixing bowl, cream the softened butter and sugar until light and fluffy.
Beat in the egg and almond extract until fully combined.
Stir in the all-purpose flour, almond flour, and salt to form a soft dough.
Divide the dough into 12 equal pieces and roll each into a thin log about 4 inches long.
Place the logs on the prepared baking sheet and press an almond into one end of each to form a fingernail.
Use a knife to add light knuckle lines across the middle of each log.
Bake for 12 to 15 minutes until the edges turn lightly golden.
Cool the cookies on the baking sheet for 5 minutes, then transfer to a wire rack.
Serve the cooled cookies with raspberry jam for dipping.
