One sunny afternoon my dad was in the workshop fixing some old furniture. I got so bored in my room and decided to join him. I saw him holding a pistol shape tool; I’ve never seen anything like it. He usually uses the typical local drill to do his thing. Still, he was almost done with the work he started some minutes ago. I just had to ask what it was holding that seems so magical.. “it’s called a cordless impact driver,” he said..” oh, an impact driver, you say?” I asked with this excitement on my face. Yes, it makes everything so fast and smooth, see I’m almost done, and it’s probably one of the best; I don’t have to use all my energy”, he said as he gave this grin… I just smiled back and left him to continue his thing.
