Looks like its the sharp square end that gouged your board. Ever see a park rail that looked like that?
When there was more snow it was pack down and the sharp edge was covered in the center. He came from the side and clipped the corner.
Any way... It is being fixed as we speak. I gave it to a local shop to get base welded because of your guys input. With a detune, wax and base weld it will cost $80. I am only going to tell my friend what the base weld costed. I learned my lesson. Never give your board to a beginner
