After doing some reading here and there, Im looking to purchase one of the Lansky sharpening systems. After looking at the different models they have Im now unsure which I need. They offer a 3 stone, 5 stone, Arkansas stone and diamond stone systems. Which do I need for just basic resharpening of pocket, skinning and kitchen knives? Also, who has the best prices on the systems like this: http://www.sharpeningsupplies.com/Universal-Lansky-Sharpening-System-P135C57.aspx?UserID=20732765&SessionID=WrOc554f{WcoRruGLcVA
