We Found a Weapon Magnet Fishing! (Potential Murder Weapon). Today we went magnet fishing and found so much stuff in a city canal. We found a potential murder weapon, a knife. We though about calling the cops, but didn’t due to the fact that the knife is a common carpenter/fishing knife. And while magnet fishing we pulled up over 11 bikes, which we later recycled. We recycled our magnet fishing finds at a recycling plant. Check out my other magnet fishing videos on my channel, as well as my other videos about History and trying new things. I use the best fishing magnets from Magnetfiskebutiken.
