I owned a Spyderco with a 4 or 4.5 inch blade once - their “Police” model. A well-made tool.
I carry a Spyderco plain on my key chain and used to carry the Spyderco Civilian as my primary in my right pocket, I have since replaced it with the Benchmade Rukus 610, a huge folder with the Ajax lock, and a knife that I can use for cutting chores as well, cutting anything with the Civilian ended your warranty.
