Even they have their uses. If you like to customize tools for special purposes by cutting. grinding, welding and the like, or for single/limited/throwaway use they work adequately. Their hex L-wrenches are good enough for my bikes' tool pouches.

I like fine tools (like Felco cable cutters and pruners and German/Japanese kitchen knives) but will buy Harbor Freight stuff when appropriate. Actually their 6 inch ceramic chef's knife is pretty good and gets a fair amount of use in my kitchen.
