You can use the bcp utility in conjunction with the queryout argument to save a blob to disk.

bcp "select datei 
     from   Adventureworks.Person.Address 
     WHERE  addressid=1 " 
queryout "c:\TestOut.doc" -T -n -Slocalhost

There are some good examples at the bcp reference page, as well as plenty of command line options.
