San Jamar Klever Kutter Box Cutter

San Jamar Klever Kutter Box Cutter

San Jamar is proud to present the Klever Kutter; the first safety cutter that prevents cut injuries, and damage to products. According to the Bureau of Labor Statistics there are over 250,000 cut injuries every year, with box cutters being the #1 cause. Each incident comes with an estimated $30,000 in medical costs, lost time, and litigation. Finally there is a solution that can eliminate cut injuries. Simply put, Klever Kutter’s unique design makes it virtually impossible for the user to cut themselves. Costly cutter injuries are a thing of the past. Klever Kutter also prevents costly damage to products. With traditional cutters, the exposed blade causes damage to cart and contents. The Food Marketing Institute estimates the cost of damaged product from box cutters is $6 billion every year. From foods to paper products, these costs can really add up. Not only from lost product, but from the time it takes to clean up a big mess. With Klever Kutter the smart design keeps contents protected, saving a lot of time and money. Klever Kutter is designed with integrated blades. You never have to slow down to try and adjust or replace blades. You also never have to risk serious injury by breaking off or replaced exposed blades. Klever Kutter features a patented double-blade design. This provides twice the life of any other disposable cutter, making Klever Kutter an outstanding value. Klever Kutter is versatile for use with a wide variety of materials and applications. From safely opening boxes to ingredient bags, Klever Kutter is the best solution for safe use in any operation. You’ve always known that great things come in small packages and Klever Kutter is no exception. Klever Kutter is the right solution for eliminating the costs and dangers of traditional cutters.

Great tool for leaving in the kitchen readily available to open packages from the mail. Wish I had this years ago. Safer to use than a pair of scissors.

from San Jose Macarons on

Easily open any box you receive with this safety cutter. Quick and easy opening packages swiftly without the worry of accidentally cutting yourself or anyone else around with the special design.


I bought the Klever Kutter for my kids to use to safely open packages and I'm happy with it. It works well once you get it started but you do need to be able to tuck the plastic corner into the box seam to get started. So if a box is taped from end to end, there's not always a place to tuck that corner of the tool in. Prior to buying this, I usually opened packages with my keys or an open pair of scissors. My kids can't quite get cuts started with keys and I'm not comfortable with them using scissors that way. I had something similar to a Klever Kutter but the blade could slide out a little too freely so I really prefer this Klever Kutter tool.


These rival the pouchmates we purchased because 1) there are two blades instead of one and 2) they are a bargain. Definitely should get a dozen of these.


These are some of the best box cutters / openers that i've ever used. I got a few of them because I get a lot of packages delivered and they are just great.

from Whole Health Dentistry on

Not the best at its one job. Just get a box of regular ol' single blade box cutters....save yourself the frustration, unless you have been praying for patience, then give these a whirl.

I love my new Klever Kutter box cutter. This thing works great. The blade is really sharp but I don’t worry about cutting myself because the blade doesn’t stick out. Also, you eliminate the chances of damaging items inside the boxes. Safest box cutter available. Even a kid can use these.


These box cutters are designed so well. Even though it's really safe it also cuts really well. I wish I discovered this product years ago


Convenient inexpensive box cutter with a safely hidden blade which makes it useful for easy and quick disassembly of cardboard boxes. Good value from Webstaurant Store.


Cuts open boxes well - and even through the cardboard. Can get stopped up on packing tape - but I'd rather ruin these on tape than a pair of scissors.

from Parfait Please on

I have 3 of these box cutters—I can’t say enough good things about it. The design is great because you can’t cut yourself accidentally. Perfect for kids to use!


This klever kutter works just as good as a box cutter, but is much safer! The blades are recessed, so it is almost impossible to cut yourself. The klever kutter works great to cut cardboard, or almost any other packaging material.


Great simple box cutter to keep on hand. It has grooves to hold comfortably and beats searching for scissors or keys every time that a box come in the mail. I would also like to note that the top edges are curved and covered in hard plastic to prevent cutting of fingers.


Such a great tool to have when you are constantly opening boxes from food deliveries and such. Works great and is very cheap so you can buy a couple

from Zeppe's Pizzeria on

This is a handy little box cutter that beats using a scissor with the blade digging into your hand . It also is safer than a dangerous and unstable box cutter


These are decent. If you are opening boxes all day, you would not want this one as the cardboard easily gets caught up and bunches into the blade area. Decent for smaller boxes maybe in an office setting.

from Rainbow Juices on

I absolutely Love this klever kutter box cutter! It has blades on both sides making it easy to use for right or left handed people.


The San Jamar Klever Kutter Box Cutter is good for opening boxes quickly. The double sided design allows the cutter to be used no matter which direction it is held.

from Lance on

This Klever Kutter Box Cutter is perfect for your pocket if you're traveling with it and don't want to get cut. Its unique design keeps you safe.


This handy little box opener is a great tool for safely opening boxes or removing box tops. The unique design keeps the blade out or reach so you can't cut yourself.
