Cordless rotary cutter

It does the cutting.You just steer.CORDLESS

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.

What changes

  • The motor makes the force. Your hand only steers.
  • Cuts thick board, carpet, foam board, screen mesh and upholstery weight fabric.
  • The edge turns behind a metal guard.
  • Cordless, so nothing to trail across the garage floor.

It cuts straight lines, not tight curves. Separate carpet from its padding before cutting, because padding clogs it.

In the field

The jobs it actually gets bought for

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

Four parts, and what each one is for

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.

Rotary blade

Does the cutting, so your grip does not have to

Powered

Blade guard

Keeps the turning edge off your hand

Fitted

Safety switch

Stops it starting in a drawer or a hand

Fitted

Grip

One hand, guiding only, no squeeze

What it does not have

  • No blades to snap off
  • No cord
  • No two handed squeeze
  • No sharpening

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 Double Duty Hand

The mechanism of the problem

The Double Duty Hand

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 blade does the work, the hand does the line

The mechanism of the answer

The blade does the work, the hand does the line

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.

The first box, and the fiftieth

What it looks like

The first box, and the fiftieth

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

Three things and one warning

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.

Three things and one warning

Charge it first

It arrives part charged. Give it a full charge before the first stack.

Let it pull

Set the blade on the edge of the board and let the tool travel. Your hand steers, it does not push.

Keep the guard down

The guard is the reason nobody gets cut. Do not work around it.

From the reviews

What people say it changed

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

Customer review

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

The ones worth answering

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.
