It's just the right size for special man things . Like the bolt and top hat spacer you allways find on the floor just after you finished servicing your bike . Stripped number plate bolts which are totally useless but you just can't throw them away . Obsolete keys which you have no idea what they might fit ? Mini buzz lightyear that you got from a kinder egg . A pack of random staples and of course , that bloody lambs foot penknife that just keeps on turning up !
