A tool is a device that can be used to produce or achieve something. Anthropologists believe that the use of tools was an important step in the evolution of mankind. Tools are the most important items that the ancient humans used to climb to the top of the food chain; by inventing tools, we were able to accomplish tasks that our bodies could not since our teeth were not sharp enough to pierce many animals' skins. If these are true then we need some good tools. Good tools help us produce and achieve something better and faster.
Pictures show some of my tools. Some of them are new some of them are old that i acquired more than 10 years ago. Good tools are nice and safe to use, good to hold, work, and last.
One that I'd like to recommend - The BMI QUICKY measuring tape. It's refined, accurate, robust, reasonably priced and lightweight that should not weigh more than 30g. That means it minimizes your pocket burden even you are carrying one all day.
