A spline is a numeric function that can define a curve. And Kershaw's Spline, designed by Les George, is a knife with plenty of curves. The first curve you'll notice is the heavy curve of the blade spine. Essentially, the blade is a modified Wharncliffe version of Les' Mini Harpy, but slimmed down all over to make it a lightweight carry. Les added a top swedge to thin the blade and lowered the tip to enhance its cutting power. The Spline offers a great all-around edge profile with exceptional push-cutting capability. 8Cr13MoV blade steel ensures the Spline's blade takes and holds its edge, while Kershaw's BlackWash finish gives it a matte finish and helps hide use scratches-because you are going to use it. The Spline's handle is steel, also finished in BlackWash, with curves that fit into your palm and give your index finger a secure curve to lock into while you work. The all-steel handles mean that the Spline also gives you a strong frame lock. For quick and easy one-handed opening, just pull back on the flipper and the Spline opens with Kershaw's SpeedSafe assisted opening. The pocketclip is left/right reversible and there's a handy lanyard hole.
