Growing old disgracefully
I use mine to do most of the work on the bike! Yes, I do need some other tools but, it's surprising how useful it is.They're intended for emergencies... crapped out at the shoulder you need to do something...
Like the lug-wrench or the jack coming in a car's kit... you'd use that once or maybe twice in a lifetime...
Whilst I'd have to admit that the spark plug wrench coming with the Honda bikes is the most practical for the job...
