New Moto Guzzi Door Mats Available Now
As a life long mechanic with a collection of ASE, Metric, Whitworth, and Brit. Std., I suggest you don't buy any tool 'till you need it. If you buy because of "maybe" future use, you'll end up with tools you'll never use.
I can sort of agree with that sentiment. I’d also recommend to not buy a full set of any special wrenches unless it is the only way to get them. I have wrench sets where I used one or maybe 2 out of a whole set for a specific job. Never found need for the rest.
