I've seen some of the work that Pakistani craftsman put out. Their handmade copies of mainstream firearms are literally a thing of beauty. Engravings and details are beyond description. That said, the metallurgy in many of those firearms is quite often very suspect. When it comes to truck /machinery repairs, they meet a market segment that is quite competitive. They fix things at the lowest cost because that is what the market demands. The repair is only going to last weeks/months until the next breakdown, but that is all that the truckers can, or are willing to pay for repairs.
