There are many tasks that require a good file and of all the tools found on SAKs & MTs the file is really the only one to use on the job - therefore it amazes me that so many SAKs lack a file. I bought a Ranger to get a file on a SAK, but most of the time I carry a Cybertool 34 (no file) but also a SwissTool so that I have a file on hand (as well as some other useful tools). I'm a computer tech and I've had a sticking power button - dismantle switch, grind a little plastic off the button, button now slides in & out as smooth as silk. When you want to grind a little wood/plastic/metal off to make something fit, that's when you are glad to have a file on your MT or SAK.
