3. what part of the blade gets sharpened?
4. the clipper keeps jamming up. name 3 potential reasons
( hair getting caught)
i cant find two other reasons
i would say they are looking for the blade is damaged as maybe another reason also i would watch the video on clippers and blades again i find i miss things all the time i almost have to re watch or re read with specific questions in mind. I also find a lot of stuff pretty vague or leaves you wondering what they are looking for.
