Today, while picking up some hunting supplies at Walmart, I checked out some Kershaws they sell. Chive, Scallion, and Leek. They were very tight to open and the assisted opening did not kick in at all. Do these knives have to be broken-in, oiled, or adjusted? I own many knives, including an older Kershaw with assisted opening. I bought it from a knife show several years ago, and it works fine. I presumed it was brand new. I was suprised that these three models were very "sticky", right out of the box. My take on this matter is maybe the blades are very light because of their small size. Has anyone experienced this with these models?
