Kudos to Buck for this one.I just received this knife. Blade is scary-sharp.Spring is strong - maybe stronger than the spring on my 70's-era Folding Hunter 110. I'm able to open this knife with good control with my right hand (I'm right handed). Opening with just the left hand is going to take some practice, or for the mechanism to loosen-up some. I can open it with my left hand, but I struggle a bit at the point where the knife is about 35% open. I docked it one star on the "ergonomic" rating because - out of the box - I really need to use two hands to open it safely when my left hand is used as the gripping hand.Pocket clip is very secure, and holds the knife so that the rest of the knife is 99% concealed in a jeans-pocket.After having handled only full-weight 110's, this knife is lightweight, and slim. But for the shape and size of the blade, you would never think it was a 110.The axis of the blade is secured by through-rivet that seems to be supported by a steel ferrule. Mechanism is not sloppy or loose whatsoever. Seems plenty sturdy for what this knife tries to be.Excellent value in a knife for the price. And its a Buck, so there is the customer-support (if you ever need it) behind the knife. I really like this knife. Although, I do still REALLY WANT the automatic 110. If only Buck would offer this knife in the lightweight configuration AND with the automatic function. Someday?
