Perfect for my Key Chain
This is the most perfect little box cutter to have on your keys. It is super small and lightweight and is so helpful to have when you need to open boxes or cut things open on the go. It is super sharp and has an extra blade inside of it so that you can switch out the blade when it gets dull. I use this thing all the time and now I can't imagine not having it on my keys. Great product!

It works
It works and is a Godsend for being so small but sometimes the blade comes out, not the extra blade, but the blade you’re using. Not often but it does happen. I use it at work everyday so it gets a workout some of those days

Switched to inferior cutter
In early December 2024 I purchased a Sheffield Mini Utility knife and I liked it very much, It was well-made and worked well for opening boxes. Two weeks later I purchased another for my son. It was a different knife. The two halves did not fit closely together, the blade carrier was plastic instead of metal, and it used a different style blades. It was a piece of junk. I wrote to Sheffield and never received a reply.

Great little knife
Great little knife, I use it all day long in my job. I like the fact the blade has multiple depth settings as the packages I open do vary quite a bit. Lightweight so you really don't even notice it in your pocket.

Nice at first
It was a really nice knife at first but it kept falling apart in the screw kept coming out I can't put my back together and then eventually it fell apart when I didn't notice and I lost the inside blade also the screw

El producto no cumple la calidad, Muy bonito y todo Pero No encaja bien A pesar que lo intente varias veces, y cuide que estaban las piezas en su lugar, Tiene un juego que no le agrada del todo, Aparte que vi que las cuchillas son algo especiales al menos aquí en México no son fácil de conseguir Te obligan a comprar la marca y son excesivamente caras Para ser un repuesto desechables
