Review on Wiha Screwdriver Quergriff 334 0X100 by Joey Richardson

I bought this T-handle because I was looking for a good quality 2.5mm Allen key that would loosen stuck screws. Unfortunately, the shaft is too flexible and you cannot use it to loosen screws that have been tightened too much. The good news is that the handle is hex all the way to the handle. So if you round off the tip you can clip/dremel the end for a new tip. That's the only reason I'm giving 4 stars. because at least you can still use it if you peel it off. Wiha tools claim to come with a lifetime warranty, but given the shipping cost compared to the cost of the key, it's probably not worth it.
