Been using mine for fifteen or so years now...love it!

I don't know what you consider a pocket knife but I use the Lansky on my small folding knives almost every day during the trapping seasons.

Lansky and systems like it operate on a very simple concept. The clamp for the blade and guide rods for the stones ensures a perfect and identical angle each and every stroke.

They offer an idiot-proof system for those of us (most of us) that can't achieve that level of precision free handing it.

For those that can get satisfactory edges by hand, there is really no need for the Lansky. It does take a bit longer to sharpen with a Lansky than it does to just whip out your knife and stone and have at it.
