The following is a series of observations based on my experiences with reel maintenance, tuning and upgrading. I do not do this professionally. I work on my own reels because I enjoy it. I started to do so a long time ago. little online research will reveal a confusing amount of information, and misinformation, about polishing internal reel components; what is often referred to as super tuning. Some of these will recommend sandpaper for certain parts. I do not recommend sandpaper be used anywhere near a reel.
The word porcupine comes from the middle or old French word porcespin, which means quill pig. Its roots derive from the Latin words porcus or pig and spina meaning thorns. Other colloquial names for the animal include quill pig. It is also referred to as the Canadian porcupine or common porcupine.
Porcupine: Porcupine, any of 25 species of large, herbivorous, quill-bearing rodents active from early evening to dawn. All have short, stocky legs, but their tails range from short to long, with some being prehensile. The quills, or spines, take various forms depending on the species, but all are modified hairs embedded in skin musculature.
