I am very satisfied with only products with a reputation. Smoothly enters the hexagon socket of the screw, smoothly escapes without being stuck. Even if it searches with Bella, Vera, wera, it does not come out, I did not notice and bought a set of V company, I will not say that it was in vain .... When searching with wera, it seems that there will be circumstances of adults in which different groups of bits are coming out without photographs, but I would be happy if you arrange a little about that. Likewise, it would be appreciated if other products can be searched by manufacturer name etc. to clarify the feature. Previously, there was something that Knipex's wire stripper (IC thermocouple can cleanly peel off) whatever you saw, but I could not order in a state with price uncertainty only for the price, I went out to the tool shop and bought it.
