Wera screwdrivers are my favorites. If you're thinking about purchasing, get your metric-to-SAE calculator out, though. The screwdriver I am reviewing is the Stainless Steel Slotted Screwdriver, Lasertip, 6.5mm Head, with the 6" (150mm) Blade Length. Phillips heads are universal, but flat-head, slotted screwdrivers might need to be converted. For instance, 6.5 mm = 1/4". Note that this is a slight keystoned-tipped screwdriver, not cabinet-tipped, although this screwdriver easily fits fasteners on 1/4" electrical wallplates, for example. One reason I chose the stainless steel version for this driver is because the handle is a different color (black-and-white, vs. black-and-green), so I have easy identification. However, there are easy-to-read identification markers on the top (end) of the handle to identify the difference between slotted and Phillips drivers. I really like the fit and feel of the handles, and they have proven to be plenty durable, at least for my usage, which is frequent home repair and maintenance – frequent enough that I like to have some professional quality hand tools to reach for. If you are a home mechanic (autos, small engine repair, light construction, etc.), the Wera "Chisel Driver" lineup might serve you better. If you read professional forums online, Wera is becoming a favorite for professional electricians. Many are abandoning the iconic Klein screwdrivers, favored by electricians for decades, for German brands, such as Wera, Wiha, and Felo, because the tips last longer under heavy, daily use and the handles are more comfortable. You will typically pay more for these imported screwdrivers, but you can catch them on sale frequently, and they are quite reasonable if you need or want this level of quality. The "Laser tips" are unique to Wera. The grooves DO increase the grip on fasteners, and you can find many demonstrations online that show this. Be aware that many pros have noted that the grooves might wear down after heavy use. However, even if the laser grooves wear down, the tips retain their tight fit on fasteners and are long-lasting. It's possible that the laser grooves on the stainless steel version of this driver might last longer. Only time will tell, and perhaps I will update this review once I apply more use. If Country Of Origin (COO) is important to your purchasing decisions, note that Wera is a German company, and their hand tools are designed there. However, most of their tools (including their screwdrivers) are manufactured in the Czech Republic. I also own screwdrivers made by Wera, Felo, Wiha, Klein, and Snap-On, and Wera's quality is comparable to all of those genuine German and USA-manufactured products, IMO. They appear to have very tight manufacturing tolerances and great quality control, based on all the Wera products I have purchased. Highly recommended!
