I was cleaning out my garage today and found this old set of bicycle tools. I don't know what they are or what they're supposed to be used for on a bicycle. Can you identify them for me?
The tool on the far left is potentially a tire spoon for removing a tire. I don't think that was its original use as it looks more like a tobacco can or possible a a patch adhesive lid tool. the second appears to be a combination flat head screwdriver and an allen wrench. The third is a brake adjustment aid. It squeezes the brake pads to the rim to allow for proper pad placement or cable adjustment. The far right is a multi size wrench. It is almost but not completely obsolete as most bikes now use allen head hardware.
The tool on the right side is a spanner with several sizes. Not exactly a top quality tool as far as spanner go, but this one was once very common in Germany. It is short and it was standard to have it in a small bag hanging underneath the back side of the saddle. I am not sure whether it is still sold nowadays.
