I have the Kershaw Leek and Blur. Got one from USA Made Blade. Someone gave me a Leek as a gift. It was my first Ker. That got me thinking I want to try another Ker. Once I held the Blur in all Black, I was in love! You know you are holding a tool. I highly recommend it if you want a 4 oz knife that is ready to work.
The Leek feels light weight and the tip, to me, is the weak point. I slightly bent mine right after I got it. I don't even know how I did it. However, with a little work and fine stone I got it back in line. So, anyone interested in the Leek, just be aware if you plan some heavy use, it probably isn't for you. I would call it a "Gentleman's" knife, if you will. I find it much lighter & thinner than the Blur. It will disappear in your pockets. Where as the Blur, you know you have it in your pocket. Also on the Leek: it has a cheesy plastic safety gizmo that you can slide to make sure the blade is locked in the closed position. I find this is kinda flimsy and comes loose. So, to solve that I slid it out of the way of the blade and screwed it down tight. So now, no more safety feature, but I haven't had a issue with it accidentally opening. And I have carried it a ton! BTW: The thing flings open with the authority of a switchblade.
You want"
Working blade: Go with the Blur and you can work it hard with no worries or regrets. Blur = cut yellow or white plastic straps off of crates.
