Have you been chided in the past with why do you haul that thing ? Yet, more often than not, it hasn't been me that has needed a road-side repair and the typical bicycle tool bundle can be bit awkward in some tight spots... Yep,
I've even fashioned a hanger splint using one piece of this with a couple of zip ties - you guessed it - on a riding partners bike !
I got this as an impulse purchase and am really happy with it. So much that I'll end up using it for things around the house and not just bike-specific tasks. Most other multi tools either don't have everything I'd want or have things I'd never use, so this is a great option since I can pick out exactly what bits I want. Otherwise it works great and the bits are available at any hardware store so it's easy to add to the collection or replace them. The compactness is also nice - I keep this in my race toolkit and barely notice it's there.
