"From wild streets and workspaces" They use the word "wild" to emphasize the ruggedness of the streets in contrast to the workspace which is usually tidy and orderly. "pioneers and poets" Another contrast, pioneers are active and move around allot often entering rough environments. Poets usually are less physically active and sit around more in safer environments. "fighters and fools to shadows and sneakers." "fighters and fools" are aggressive, rash and prone to damage. "shadows and sneakers" refer to people who move like shadows, carefully and quietly. All in all the poem is just stating that this wallet is suitable for any person in any place.

This is simply saying, in a poetic way, that the wallet could be used by any man. By using things that are very different, the writer is saying that no one is outside of the group that could use it. "Wild streets and workspaces" basically means "any place". The rest is similar to saying "no matter what kind of work you do".

Sounds like it might be from a poem? Anyway, wild streets could refer to the streets of the Wild West, which were filled with gunfighters. That is a guess, but I think I might be right. Workplaces are much more calm and organized/structured
