I carried a SpyderCo Delica for years until I lost it and was pissed. I bought a Benchmade Aphid that I carried for a bit before I gave it to my brother as a New Zealand present when he left the US to shear sheep with the Kiwis.
Now I carry an Benchmade Axis (580S assisted open):
I'm not gonna lie, I've cut my fair share of triple caps with this puppy.
The knife that's in my car is the SOG Seal Pup which has survived many a backpacking excursion, salt water use, and backpacking in Italy and New Zealand. I love that knife.
My other regulars are Buck hunters, the SOG Northwestern Ranger, classic Leatherman tool, SOG tool, Gerber tool, and assorted Swiss Armies I've picked up throughout the years. I am dying for the Benchmade Infidel next...but for now it's way out of my paygrade. Summer is the slow season.
