I have carried this Kershaw Leek since 2006, and couldn't be happier with it. It has met every need I have had for 15 years. It's solid, opens quick as a auto knife, open/close one handed, takes a great edge, and holds it. What more do you want, and it only set me back $45, believe the MSRP is $70, but can be found a lot of places for less.
