The Spyderco works GREAT at home. I usually put it on a TV dinner food tray and sharpen while watching the TV.At home I have the Ken Oniom edition Worksharp. After the Ex fine belt I use a razor strop. Shaving sharp. Got by for many years with Spyderco tri angle sharpener. Might have to try the Lanski sharpener. Just carried the Spyderco because I had it. Mine is the old one in the cloth case.
The Lansky is small and light to carry in a backpack. We just keep them in case we need to sharpen (touch up) a knife. We always carry several knives so when field dressing we always have a sharp knife. Say if you are shooting several animals you may need to touch up a blade. You won't carry your main Knife Sharpening Kit.
