When a cut isn't bleeding very much, is bleeding controllably, isn't very deep, and wasn't caused by a dirty or rusted object, then it's minor and will heal on its own or with basic care at home. However, if a cut is bleeding a lot (but not excessively), if a cut is somewhat deep, or if a cut was caused by a dirty or rusted object, then the cut may require stitches and/or a tetanus shot. Most importantly, if a cut is bleeding excessively and/or uncontrollably, then you must dial 911 for emergency care. Only if the bleeding is minor and under control can you seek care at urgent care.
