Like James, I carry a partially serrated Spyderco Native when working around the house (in my weekend jeans). Much better for cutting vegetation, carpets and the common yard and house use.

Like others I have and use both for their specific strengths. A sharp straight edge will cut a seatbelt or rope almost as well as a serrated edge, it just won't do it more than a few times. It also will NOT cut warm bread as well :-)!!!

Several have indicated a problem in sharpening a serrated edge. Sal Glesser (the owner of Spyderco) designed the Triangle sharpener - which allowed him to start selling serrated knives. The Triangle makes sharpening serrated edges almost as easy as straight ones.

Full disclosure - I have had Sal as a friend since before he made his first knife.

Respectfully,

Jerry
