Rotary blade
Does the cutting, so your grip does not have to
Powered
Cordless rotary cutter
Cutting cardboard by hand asks one hand to do two competing jobs at once: make the cutting force, and steer the line. Both run through the same small muscles and the same thumb joint. That is why it hurts, why it gives up on thick board, and why people cut themselves on box nine rather than box one.
It cuts straight lines, not tight curves. Separate carpet from its padding before cutting, because padding clogs it.
Free over $79, otherwise $9.95. Orders leave in 1 to 2 business days and arrive in 7 to 12.
Sixty days. Use it properly first.
In the field
People buy it for the recycling bin and then find the rest. Carpet out of a flooded basement. Five rooms of it. Foam board, screen mesh, quilt fabric, book board, pet food sacks.



The tool
There is no clever chemistry here. It is a small rotary blade, a guard, a switch and a grip, and the whole argument is about which of them your hand is responsible for.

We have not confirmed blade diameter, runtime per charge or a maximum rated thickness with the supplier, so you will not find those numbers anywhere on this page. When we have them in writing, they go here.
Box nine
People do not cut themselves on box one. They cut themselves on box nine.
The failure is cumulative. Your grip is doing the cutting, so it fatigues, and a tired grip is a slipping grip. That is why the injury and the giving up both arrive late in the stack rather than at the start of it.

The mechanism of the problem
Scissors and a box cutter both ask one hand to generate the force and steer the line at the same time. Those are competing jobs and they run through the same small muscles and the same thumb joint.
That is why sharper scissors did not fix it, a fresh blade did not fix it, and better technique did not fix it. All three were variations on asking one hand to do two jobs.
Every previous fix you tried was a variation on the same wrong idea.

The mechanism of the answer
A powered rotary blade separates the two jobs. The motor makes the cutting force. Your hand is left with steering, which is the job a hand is actually good at.
The blade turns behind a metal guard, so the edge is not the part meeting your fingers. That is the difference people describe when they say nobody got cut this time.
Your grip stops being the engine.

What it looks like
The first box: you will over steer it. The tool wants to travel and your instinct is still to push. Let it pull itself along the line and follow.
By the fiftieth: you are cutting a flat screen box down while something is on in the background, and the bin closes. This is the part reviewers describe rather than the first cut.
It cuts straight lines, not tight curves. Learn that early and it stops being a limitation.
How to use it
If you have never taken a daily pill in your life, this is about the most we would ask of you. Put the bottle next to the coffee and it takes care of itself.

It arrives part charged. Give it a full charge before the first stack.
Set the blade on the edge of the board and let the tool travel. Your hand steers, it does not push.
The guard is the reason nobody gets cut. Do not work around it.
Against the alternatives
Named by category, not by brand, because the comparison is with the method rather than with anyone's product.

From the reviews
Quoted exactly as written, typos included. We have no star rating to show you yet, so there is not one on this page.
At 79 years of age, cutting boxes with knives & scissors was the bane of my existence - sometimes taking hours due to the stack that accumulated.
Customer review
I have Arthritis in my thumbs so using this is so much easier than using regular scissors to cut/break down cardboard boxes.
Customer review
Great tool cut about 1100 sq. Feet of wet carpet out of my flooded basement with ease!
Customer review
Super easy to use and no one got cut which is a normal occurrence for me when cutting boxes.
Customer review
There's so much more eoom in recycling bin now that I can cut things smaller.

Use it on the stack that is actually in your garage, not on one test box. If it does not do what this page says, tell us inside sixty days and we will make it right.
Questions
No. It cuts straight lines. For tight curves you still want shears.
Separate them first. Padding clogs it.
We are not going to give you a number we have not confirmed with the supplier. It goes through appliance and moving boxes and pet food sacks, which is what people buy it for.
It is a rotary blade rather than a snap off one. Whether a spare ships in the box is something we are confirming.
It is a one handed tool. We have not published a weight because we have not confirmed one.
This is a cutting tool with a powered rotary blade behind a guard. Keep fingers and loose clothing clear of the blade, use the safety switch, and keep it away from children. It cuts straight lines rather than tight curves, and carpet should be separated from its padding before cutting because padding clogs it. It is not a substitute for a rated tool on a job that requires one.
