I just got a Leatherman Surge. I was going through all of the tools and noticed that the saw blade in the blade exchanger seems to have some play in it. There is enough play that when I shake or tap it the saw moves around somewhat loosely. Is this normal? I swapped it in and out with the file and it was still was the same. Should I take this back and try to exchange it for a different one or is this normal for this tool?
