Hi, I’m hoping someone can help, I’m new to grooming. I bought a new Oster 10# blade to replace the original because I thought the first blade was dull. The new blade lasted for one grooming session and now just fills up with hair and doesn’t cut. I do oil the blade before, during, and after use. I wipe the blade and clear as much hair as possible also. Any advice? Are there some specific steps I should be following? Thanks!
