Flaring tool.

Not to sound to pedantic but your brakes are quite important and if there is one area that you shouldnt really scrimp on its your brakes.I think that a decent tool will pay dividends even if you only use it once.Maybe worth doing a loan one as done with the axminster reamer for the uprights and passing it around so that people can make a quality set of brakelines and the tool gets maximum use for the monetary outlay.
