Ran brake cables through the frame housing for 3 years before I caught my mistake
Back in 2019 I picked up a Park Tool cable cutter and noticed my cuts kept fraying no matter how hard I squeezed. Turned out I was cutting the housing with the dull side of the jaw the entire time, and a guy at the bike co-op in Fort Collins named Dale showed me the right side in about 10 seconds. I felt pretty dumb standing there with 6 inches of frayed cable in my hand. Anyone else learn a basic tool trick way too late because nobody ever pointed it out?
