Amazing
This makes opening boxes and cutting up the recycling a breeze, and there's no risk of accidentally cutting yourself with the retracting ceramic blade. I wouldn't have bought it at the higher price but when it's back to a more sensible figure it's a great purchase.

High quality box cutters
Very good quality box cutters, cuts through the vast majority of cardboard packaging with ease. Absolute must have if you want to break-down your recycling into more manageable sizes, easy to hold and sharpe but safe ceramic blade.

This is fab
Wasn't expecting much with ceramic blade but it works Brill. Carved up loads and loads of cardboard easily for the ♻️ recycling. Happy days. Just ordered some replacement blades for it but having said that, the one which came pre installed shows no signs of getting blunt and of course if it does its easy to turn around and refit

Works very well. A bit pricey but I had a lot of boxes to cut up.

It does the job
Due to lockdown and not being able to get to the recycling centre, my car was full of cardboard boxes. I know from experience that our kerbside recycling won’t take the larger boxes so I needed a solution to cut them down to a size they would take (70cm it seems). I thought the reviews on this were a bit hit or miss and it’s not the cheapest thing to buy for this one purpose however what else is there to do nowadays? It arrived and first impression was it was much bigger than I expected so feels solid and allows a good grip. I grabbed a box and started my slicing routine. It was incredibly easy to carve up single and double walled cardboard boxes and my stockpile was quickly reduced suitable (hopefully) for my next kerbside collection. My plan now is to keep cutting up the boxes as they arrive to never find myself with a car load of cardboard. My life is improved. My wife is happy and lockdown life just got a little more bearable.

Now this is The Business
The page says it all. An amazing ability to cut through box seals - in total safety! Very effective; effortless. It's actually a lot bigger than I thought. Awesome. Best buy for a long time.

IT'S JUST A PRETTY FACE
I was most attracted by the good looks of this knife, but performance is not impressive. It is a struggle to get it to cut through thick cardboard (the dreaded recycling rules), and I usually end up using a good carving knife.

Easy to use
Handy to keep in the cutlery drawer, saves me using a knife to open parcels - easy to use.
