Review: desertcart beats Stan - I have had -and lost- several knives of this sort over the years. All have been by the brand leader and, as a result, my expectations of them were high. However, they never quite lived up to expectationsas I found small but significant shortcomings in ease of use, convenience, and ease of changing blades. I had lost yet another and needing a replacement, I thought I'd give the desertcart Basics one a try, partly because of the price, good reviews, the description and apparent ease of use. The next day delivery provided by desertcart was another factor in its favour. It arrived yesterday and I soon got the immediate job I needed it for done and dusted. How I wish I'd bought one of these before. The first thing that was pleasing was the sensible packaging it came in - none of that stupid plastic bubble stuff that's impossible to get into without some cutting tool - stanley knife anyone????!!!!. Mercifully, mine arrived in a small but solid cardboard box. And yes, there were instructions although desertcart's site had video's and pdf versions of the instructions too. Actually the instructions are almost redundant. Once you have twigged to the purpose of the red plasic lock widget, how to remove it and and also put it back, the basic usage of the knife is pretty self evident. There are a couple of settings that allow the blade to be used with one of three possible blade extensions making it useful for different cutting jobs. Although there's no blade auto-change facility - given the price I wouldn't expect this - the folding design makes it very easy to change blades manually - the knife can hold three spare blades in the handle. The simplicity means there's less to go wrong too, always a virtue in my book. The knife seems well made and I like the design which is well thought out and provides a good balance between ease of use, convenience, and price without safety being sacrificed. Only real minus point is that plastic locking widget. It is perhaps too easy to lose and given the important role it plays in storing the knife safely, some way of making it an integral part of the knive seems desirable. Nevertheless, I'll stick with 5 stars as I can't award 4.5
Review: Good quality at a good price point - Good value yet high quality item, having spent the afternoon chopping up boxes with it I can confirm that it feels good in the hand and made box disammebly a breeze. As you'd expect, the blades are sharp and the mechanism for replacing them is very straightforward. The design of the knife as a whole is pretty clever and leaves you with a nicely self contained device. After using it for several hours it wasn't too heavy or overly fatiguing to use for prolonged periods, it made the whole job a breeze so works very well. Given how sharp it was I didn't have to force it through anything so also feels pretty safe to use.

### ⭐⭐⭐⭐ Decent
*by D***. on 14 November 2025*

Nice sturdy box cutter. Only complaint is the similarity of the ‘extend blade’ button and the ‘open case’ button. Very easy to pop the whole thing open when you’re just trying to pop the blade out
