What size do you need? Many experienced carpenters use a 16 oz. claw hammer for most jobs, but also carry a 20 or 22 oz. framing hammer for their heavier nailing jobs requiring big spikes. For lighter work, a 13 oz. curved claw hammer can be useful. Even a 7 oz. hammer will come in handy for smaller jobs like making picture frames.
How often have you been at the store, knowing you should pick up a filter, humidifier pad, vacuum bag or plumbing part, but don’t remember the size or the part number? A solution is to make up a Òparts cardÓ the size of a business card to carry in your billfold. Write down the part numbers on it for all your home or equipment parts that need regular replacement, and add to it as needed.
