This is a nice double pointed leaf shaped blade. It is flat on one side and almost uni-face but it does have some edgework all the way around it. It still has some or the outer rind of chalk from the flint nodgule present.
Here is a thin blade made from the outer core of a flint nodule. It was only worked on the one edge with fine pressure flaking. A possible nick on the end was possibly done during manufacture. The patina there matches the rest of the blade.
