If you could only carry one, which would you carry?

Large substantial folder like a Sebenza or RSK.

or

Large quality multi tool like a Leatherman Wave or Charge.

If you have a particular job that requires the use of tools a lot try not to factor that in. Think of yourself as the average Joe Shmo living a typical America urban/suburban/cubical lifestyle.

Both items are roughly the same size however (if using the RSK as a knife example) the multi tool is about double the weight in your pocket.

Since receiving my pocket clip for my Wave I have been switching back and forth between it and a RSK and just can't decide which to carry for EDC.
