Your pencil is human-powered it only stops when you stop writing. Easy to sharpen with a variety of readily available items: knife pencil sharpener sharp object etc. So do yourself a favor and always have your trusty pencil available you'll be a hero at the next meeting when the skype TEAMS zoom or whatever goes out of service. Carry On!!
