What brand is your favorite tape measure?

You don't need to swing twice as hard if you have half the weight. I've used these light hammers since the mid 90s. It is surely because of this that I have NO elbow or wrist problems, NO carpal tunnel issues either. Lots of old time Carpenters that I worked around 30 years ago thought that "The heavier, the better" but they also worked in pain and drank a lot! Nail guns are popular now for almost every instance so the hammer is not used nearly as much as it was 30 years ago.
You have more control when swinging less weight. If I have to whack something 3 times instead of once, the three swings still take less energy than the one heavy swing. Think of how this applies to weight lifting. If you can bench press 200 lbs once but also lift 100 25 times, isn't it much easier to lift that 100 lbs 3 or 4 times?
