Slightly off-topic but here's a quick shot of the Megadora 930s sitting in my Assistent. Same handle shape as the Megadora 900s in your picture but with integrated hex bolsters and tang-thru striking caps like the power grip line.Yes, I have some of both, but the answer depends on the age of the tool.
If you are considering the older Hazet drivers, with the blue wooden handle, they are very decent. The handles are not the most durable, but they were fine for the time. The blades are first class in every respect. I have not seen Vessel drivers from the same period, but I would suspect the Hazet to be the better tool.
If you are thinking of the later Hazet drivers with the yellow acetate handles, then I think they are the best Hazet drivers ever made, with durable handles and superb forged blades. Better than the Vessel of the period I think.
Of the current tools, the Hazet drivers are made by Oplast in Slovenia. They make different grades, at different prices. They’re not bad tools. The best grade is the “Trinamic”. I own quite a few of these, and they are decent, especially for the price.
However, while so many tool manufacturers look to reduce the range of tools they make in house, and reduce costs generally, the Japanese try to make BETTER tools. If the trend continues, they will eventually succeed.
The Vessel “Megadora” is, in my opinion, a slightly better tool than the Hazet Trinamic. I actually prefer the handle of the Trinamic for dirty conditions, but the blades of the Megadora are superior.
If you consider the best screwdriver that Vessel offer, which is the Powergrip, then there is no contest, the Vessel is superior in every respect. The blades are stronger, they are better forged, better finished, and the handles are superior. To give an example, the Trinamic appear to have a forged hex bolster, but in reality this is a separate piece. The Vessel is forged in one piece.![]()
