The first aspect to think about is the length. Short screwdrivers can be handy if you need to get into a constricted space. Long ones also play an important role when you need to get down into a tight spot. Both lengths are worth carrying because you never know how a situation may play out.
Another important aspect is the grip. If you can't get a good hold on your screwdriver, you can't properly use it. In many cases, when you are using this tool, it is not the most ideal circumstances. Your hand may be greasy or dirty, so grip becomes even more critical. You want to find one that is ergonomic and has a nice material on the handle that will give you a good hold on the tool.
Lastly and most importantly, it would help if you had screwdrivers of all types. Whether you have one set bit or interchangeable ones, you need to ensure you have a varied collection. You don't want to think you have the right tool only to find out you don't have the one you need.
Screwdriver bits come in a variety of shapes and styles, including flatheads and Philips, and they are not interchangeable. In addition, each style comes in different sizes, so even if you have a flathead in your collection, it may not be the right size for your next project. It is well worth it to gather a selection of screwdrivers, so you always have the one you need.
Luckily, there is an excellent range of choices when it comes to this standard tool. You can choose from all your favourite brands, including Irwin and Stanley, to get the screwdriver you need for your tool collection. You can even buy just bits, which make the ideal way to save space if that is a concern for you. In the end, all that matters is when you need a specific screwdriver, you have it on hand.
