Perhaps he is scraping dried dog poo off the foot peg. But seriously, it doesn't look like a tool I would use on that part on a motorcycle. Nor does it look like the conditions, place or lighting that I would work on a motorcycle. To me it looks like ad copy from someone that doesn't carry a knife or work on motorcycles very much. By the way, that motorcycle is way too clean. He apparently doesn't ride much either. LOL
