I've been working as a temp recently, mostly in a manufacturing environment. Since I'm only a temp right now, I don't have super consistent hours. However, during my time working last week, I cut a variety of things, ranging from a sandwich to tape and plastic, and on one of my shifts I spent a couple hours straight cutting up some cardboard for a specific job. I used my Benchmade 531 Pardue for the cardboard. It worked well and got the job done, but it got almost painful by the end, and the edge seemed to be pretty dull by the time I was done. When I described the situation to an acquaintance in the community, he suggested Zero Tolerance, specifically one designed by Rick Hinderer, as they have impressive ergonomics.
That being said, I'll gladly look into any recommendations! I do already own a Buck 110, but the two handed open and close isn't great for how I expect to be using it and for the specific environment. I've had it for a couple years, and it does still stand as my favorite outdoors/camping knife to this day!
