DOWELL Utility Knife Retractable Utility Knife Box Cutters Heavy Duty with 5PCS Extra Blades,Self Loading Blades Function,Knob On Top Can Withstand More Pressure

Wow, I really like this utility knife! At first I thought it was a little heavy but after using it for 25 minutes straight cutting down boxes, I didn't find it heavy at all! And I really like how it performs and the blades are Sharp! I was curious as to how sharp the blade would be on 40 boxes that I had to cut down, but it was just as sharp on the 40th box as it was on the 1st, which really is not what generally happens with my other blades! Looks like the Dowell Utility Knife was an exceptionally good buy for the price!

Convenient. Sturdy. Storage. Relatively easy to use. Blade does not lock and will retract when cutting heavy material. You have to use the set screw to keep the blade in place. But, then you need to back off the set screw to retract the blade. Cuts well and I like having extra blades in the handle.

The knife's extend & retract work very smoothly. The lock is very useful to secure the blade when extended far. The blade auto-load feature is the best! It holds 5 blades and instantly loads a new one when needed. The handle seems sturdy and grip feels very secure. I used this to make several animatronic Halloween props this year. I kept this in my pocket because I used it so often. Having a long razor-sharp blade at the ready was a huge time saver for me. My only complaint is with the little locking screw. It works, but it takes 2 hands to lock and unlock the blade, and the screw will fall out if you don't keep slight pressure on it at all times.

I was really hoping this DOWELL Utility Knife would be a solid addition to my toolbox, especially since it comes with extra blades and promises a heavy-duty design. Unfortunately, the overall mechanism just doesn’t hold up to expectations. The biggest issue is with the retractable blade system — it feels rough and inconsistent. The self-loading function sounds convenient in theory, but in practice, it tends to jam or misalign, making it frustrating to switch blades quickly. The knob on top, which is supposed to provide stability and handle more pressure, doesn’t feel very secure. When I tried cutting through medium-thickness cardboard, the blade wobbled slightly, reducing precision and confidence in use. The handle itself has decent weight, and the design looks solid, but functionally, it doesn’t deliver. I also noticed that the blade lock doesn’t always engage properly, which can be concerning for safety during tougher cuts. It’s clear the product had good intentions — self-loading blades and a pressure knob are smart features on paper — but the execution needs improvement. For light-duty tasks it might be passable, but for anyone expecting a dependable heavy-duty cutter, this one will likely disappoint. I appreciate the effort in design and packaging, but given the unreliable mechanism, I can’t recommend it. Hopefully, future versions refine the internal mechanics to match the sturdy look of the knife.

Broke after a couple months of use. My dollar store utility knife has outlasted this one by ages

I've used several different styles of box cutters like this over the last 10 years, working in a hospital warehouse. I had a holster made for an old box cutter of this style for my belt, that's no longer manufactured and I've had difficulty finding another one that I like. The screw safety is nice, it doesn't get in the way, and it fits in my belt holster. The outside is plastic, but the part that holds all the blades is metal, and it uses universal style blades. I'm really happy with this, looking forward to breaking down boxes with it.

Thank you very much

Don't know why I waited so long to buy a good box cutter!. I am surprised how often I use this instead of reaching for scissors or a knife especially with frequent Amazon deliveries . Easy to use, great quality and price. Recommended.
