Blade just falls out, rapid load joke
Impossible! the blade will not lock in place, I believe they either supplied the wrong blades or this is an insanely poor design.

Awful product
I am very disappointed in my dewalt DWHT10046 box cutter. It will not hold the blade and now is a huge waste of money.

Not as convenient as portrayed
Rapid load is a pain. Otherwise has good grip and feels solid.

Great construction, blade change is a chore
Bought 2 of these and 2 of the folding ones which are a very similar style except they fold at my local Ace. I liked the construction and weight very much. They have a good heft to them and they feel great in your hand. I especially like the fact that the front of the knife is slightly bent. They also hold a few spare blades in the handle and have a rope cutter slot as well.

All was well until the first blade change. The mechanism for blade change is hit or miss at best. The small black button has to be depressed with a lot of force and it sometimes releases the blade and other times it doesn't. I couldn't figure out why it would release sometimes and other times not. I took to holding the blade with a pair of pliers so I wouldn't cut myself.

It's a shame because other than that, the construction is top rate and it is one of my favorite utility knives to use.

Overall good quality, very easy to use when common sense is applied. Blade change is quick and easy.
I have continued to purchase Dewalt product over the years and always look forward to Adding more Dewalt tools to my Collection.
Take care and pride of your tools and they will take care of you.

I bought this item from Home Depot a few weeks ago and just tried to use it. From the MINIMAL pic instruction I found the 5 blades in the handle and inserted one ad shown. Now the blade will not protrude nor dislodge rendering the cutter useless.

I built this along with a cheaper utility knife. Well I was up and using the cheap (half the Price model in no time. The DHWT10046 took a half hour and then a got on to the site to see if I could get instructions.... well no such luck. I bought it because of the name and design. Well execution of the design is a total process and DeWALT missed a simple step

Blade comes out too easily
I bought this 2 days ago and have to take it back. It's easy enough to load new blades since I've had similar knives in the past. However, after using it for only a few minutes cutting up cardboard boxes, the blade began to pull out of the knife. I'd push it back in but it doesn't stay "locked" in the tool and keeps pulling out. After using it for maybe 10 minutes, I can now simply grab the end of the blade and pull it out without pressing the button that's supposed to keep it locked in place. Hey, DeWalt ... this is pretty old and simple technology. I'm surprised you didn't get it right.

Impossible to change blades
Nice design for ergonomics but it's impossible to change blades. There are no instructions on how to change them. I've had to use the same blade for months. Time to toss it in the trash.
