This. This is the best box opener I've ever had! I started working in the store's shipping department and didn't like the cutters that came with it. They fell apart when dropped and weren't deep enough to cut through layers of tape and cardboard, so I started buying my own. I saw this one but couldn't really justify paying close to $20 for a cutter. However, a year later and 2 promotions I see this as an investment in a trading tool and I'm really glad I finally broke down and bought it. It fits comfortably in my hand and easily slips into my pocket when I'm not using it. I'm the envy of all my peers, and it cuts like a hot knife through butter. I can eventually see the rubber coming off the handle but tape will fix that. Probably the last box opener I will ever buy. I also have a green one that retracts automatically because it's faster for me. Even my customers ask for it!
