i wanted to "test the waters" so to speak on OTF knives without spending a ton of money. the Lightning OTF that I purchased from Perry's Knife Works was very reasonably priced. I haven't had it long so I haven't had a chance to work it hard but for the money the knife seems very solid. The opening/closing action is VERY crisp and though there is the typical side play in the knife, it is certainly not excessive. I am very happy with this purchase AND with Perry's.
