Total cost to me, the price of writing a quick note. Now that's service! Kershaw makes a quality product and supports it well; I'm happy to recommend them to you

I was asked by another blogger if I found the tips of these blades fragile. They're certainly not screwdrivers or prybars; the blade shape and profile are such that the very end of the tip is quite fine. The blade becomes much more substantial around 3/8" back. If you were planning on using a pair to scale a wall, you will need to drive them in deeply (this use probably voids the warranty, BTW). As knives, they're just right for me; the slender shape of the tip spares me having to carry a penknife for fine work. When I have been inadvertently rough on the blade end, I was able to bend it back with a vise and a bit of effort, which is impressive resilience for a blade that holds an edge as well as these do. (The little Japanese carpenter's knives I carry as a backup and for precision wire stripping take a slightly keener edge -- and snap like glass under bending stress.) YMMV; there are plenty of choices and you should fit your knife to how you'll use it.
As the old adage has it, "Two is one and one is none." The reason I keep using the plural is my daily carry knives are pairs: one in my pocket, one stored at home in case of loss or damage. I carry two knives (of different sizes) plus a Leatherman "Wave." The first rule of having a knife when you need one is to have a knife.
