Hi i just but a hair clipper and i want to do my sides and beard by outlining them?

the problem is the hair clipper doesn't cut well I've adjusted the blade and power, this isn't the only time all the hair clippers i bought always did the same thing, i don't know if the blades aren't sharp or what it is

If you bought clippers, the bigger ones that are used for cutting hair, they usually won't get close enough to do outlining. You need to get some Wahl trimmers...... they are smaller and will get much closer. Easier to work with too. But don't get the battery operated ones, they lose power too fast. Get the rechargeable ones. Keep them fully charged.
