Both of my Endura 4 Spyderco knives boast a half-serrated blade. I find this to be perfect for most of my utilitarian needs, and they are more than capable of slashing a seat belt or dicing a tomato. The blade geometry is excellent and holds an edge well. I enjoy the fact that the design is not overbuilt, and it is elegant enough for most kitchen needs. However, it is a bit wide if you want to make it pull double duty as a regular paring knife for hard vegetables like carrots.
What I appreciate most is that the blade has been easy to carry and reliable. The VG-10 stainless steel has survived everything from deserts and mountains to ocean beaches. You can shave the hair on your arm with the new blade and, with minor resharpening from time to time, the abused old one does just as well.
This is by no means a small pocketknife, but it is deceitfully slender and light in the pocket. My scales put the Endura 4 at 3.6 ounces with a total length of 8.7 inches and a cutting blade length of 3.38 inches. You can compare that to my Cold Steel Recon 1 at 5.4 ounces and 9.25 inches or a mid-sized Kershaw Emerson at 7 inches and 3.9 ounces. Any way you cut it, the Spyderco blade provides a light, slender carry companion. My original still has a very grippy and positive handle.
When I need something smaller, I often reach for my Spyderco Clip. That knife has been a fantastic go-to whenever I need to put on the fancy attire or just want a practical secondary blade. They come with various secondary tools, but I tend to favor the secondary serrated blade. Bottle openers are also available. Again, the blade geometry on these knives is great.
