I have had those, and they can break. Now I just make them from stainless table knives, heat and bend the end, cut the prongs to shape with a dremel cut-off wheel. When it breaks you dremel off the end and make another.
When you need to use such a pin-tool near the limit, clamp it to the chainring with a pair of wood blocks; have the back one overhang the whole tool, and the front one leave clearance for the hex key. It helps if you can brace the tool against another part of the crankset.
