I love this Knife. I've got 4 of them now and have had a few of them for more than 6 years.
I love the quick change feature and the blade storage in the handle is amazingly convenient and very easy to use. The feel and weight of the knife is nice and it fits in the hand very comfortably.
I was surprised to see that this knife had a one star review from someone, because I love these blades. I got my first one around 2005 or 2006, and I quickly decided that it was the best utility knife I had ever owned.
The only one of them I've ever had break, broke because I was trying to cut a really hard to get to cut-out in a piece of vinyl siding and I was using a hammer to beat on the top of the knife to drive the blade down. Given, that was not the intended use for the knife, but it got the job done, and the blade is still fully functional, the damage to the blade was purely cosmetic and it still works great. Not to mention that particular blade has seen extremely heavy use since the day I bought it.
I guess with any product one buys they run the chance of getting a lemon, and maybe that's what happened to the other reviewer, because like I said, I have four of these and everyone of them is awesome. I actually bought another one a few days ago and it's feel and weight seem identical to the other ones I already owned. I'm very happy with this particular product.
Pros: Durable, Easy to Use, Sturdy, Strong, Good Size & Weight, Light Weight, Long-Lasting, really convenient
