Pacific Handy Cutter S4R Safety Cutter

Works great, much better than the blue ambidextrous ones. It can hold a bunch of extra blades in the hilt, and is very easy to clean/lubricate. Fits in the hand well, and has yet to let me down. I’ve used this bad boy every day for a few years now. The blades that are made for it will cut anything you throw at it, and last a pretty decent time before getting too dull.

Knife is a excellent to work in warehouse environment

Work in a retail job and have been using this knife for years. The last one lasted me 4+ yrs...it's comfortable and perfect for my daily use.

I HEAVILY rely on the s4’s overall durability. Nice grip. Great cut guard. A little dab of machine oil and you’re set for a lot of cutting!

Best box cutter for cardboard boxes. There is a belt clip available for this model but fits well in your pocket, so I never bothered. Important modification. I ground off the "tape breaker point". It is not needed and just pokes wholes in you pocket lining. You can use a grinder or mettal file. The metal is soft iron. One of them I ground off the tape breaker at work for a friends by scraping it back and forth on the rough concreate. That worked just fine also. I have always carried these in my pockets for more than 20 years now. The original I bought is still working strong. Needs a little oil now and then to keep it opening and closing smoothly. For all day warehouse work. I change to a new blade about once a week. Buy extra blades. They are cheaper with today dollars, than tommorow dollars.
