Well here is my verdict on Toptul's standard screwdrivers.
I'll start off with the tip and shank of the screwdriver. So far I've exposed some of my screwdrivers well over a thousand times to a fastener. I've been using these screwdrivers daily for at least 4 months and the tips are holding up fine showing minimal signs of wear. In fact most of which happens to be residue left from corroded fasteners. Also, the tips are magnetized and seem to be more powerful that most screwdrivers. The shanks are also in near perfect condition. There is no evidence of deformation and the shanks stay true to the handle.
The handle is my favorite part of these screwdrivers. Off the bat these handles feature a composite material that feels very similar to the composite material found in Snap-on's comfort grip ratchet handles. Anyways the composite material is very ridgid. I have no doubt in my mind that they could withstand muiltiple blows from a hammer. The other material used in the handle is a thermo-plastic rubber which feels soft and resilient giving the handle a comfortable and secure grip.
I figured I'd post this auto-cad drawing from Toptul's website to give a visual reference when reading the following below...
The ergonomics of the handle feel much better than many of the screwdrivers I've been accustomed to. My hands tend to be smaller than the average adult so finding a screwdriver that mates well with my hands seems to be rare. Where the handle and shank meet, the composite material has a rounded triangular shape with three indentations about a centimeter down along the flats of the triangular shape. This is where the composite and TPR material meet as well. The handle is also thinner in this section compared to where the shank and handle meet, and where your palm would rest.
After the three indentations, the rest of the handle is TPR until the very end on the cap which is composite. where the handle and palm would contact, the TPR features a textured surface giving the palms even more grip. At first I was worried that the textured surface would wear out over time, but I still see not signs of wear. At this location of the screwdriver, the handle takes the shape of a rounded hexagon. The Toptul logo is also featured in this location as well (which is a raised section of the composite material.) On the opposite side of the screwdriver is where the model number, size information and DIN standard. There is also a picture of the type of fastener that the screwdriver is used for. All of this information found on the screwdriver is laser printed and shows signs of wearing off consistently throughout the ones I normally use. Lastly is the cap where as said before is composite and rounded.
Overall I am very impressed with the quality of Toptul's screwdrivers. The tips seem to hold their own and show no signs of quitting anytime soon. The ergonomics are superior to practically every screwdriver I've used, though this opinion will vary from person to person. I've liked them enough that I will be replacing all my screwdrivers with Toptul.
