Separate toolkit with each bike? Or one per bike?

[I like Skol]

Aside from the bickering the repair/rescue debate has generated, I actually think this misses the main point. If you are prepared and capable of repairing issues at the roadside you can set out confident that your ride won't be ruined unless you experience a catastrophic failure.
On that one warm, sunny, Sunday of the year when you set out on a memorable ride that you have been looking forward to for months, the last thing you want is for your ride to be cut short after 10-15 miles because you suffer a minor, easily fixable mechanical.
A puncture, broken chain or loose handlebars can all be cured in minutes, but without basic tools can mean the end of your day when you would much rather enjoy the rest of the trip with your friends.

My attitude is to enjoy the ride, to the end.

This thread has inspired me to make a list of tools for each of my four bikes, make a shopping list and get stuff ordered.

No more worn allen keys, no more wrong inner tubes or inadequate tyre levers. My tourer is getting a pedal spanner.

Feels good.

I usually carry my “water bottle” kit

I also have a more basic smaller kit in a Topeak saddle bag for short city rides. And of course the very clever Brompton tool kit slid into the frame of my M3L
