Large Knife
The 4" version of the X5 is a large knife. The advantage is that it is easier to grip and has more blade for cutting. The disadvantage is that it takes up more pocket and is harder to flip open. For me, the 4" Hogue knives feel better in my hands than the 3.5" ones. The materials and build quality are very high, but you will have to bend the pocket clip a little to make it work better. This price point, though, is the best I have found anywhere online. If you are buying the X5 to have a large knife then you will be happy with the purchase.
