I'm like you. I can do quite a few different things except I cant do masonry, but I have hobby machinist on my list . Anyway I didn't have a small torque wrench or small metric allen sockets and I was going to be doing quite a bit of work to my bike so I bought one of these on a whim.

I usually dont like buying "kits" as they are always lacking in some respect. I'm really enjoying this kit though, most of the time I don't need anything else.
