Difficult to load
I am a contractor and use utility knives quite often. However loading this one is not easy. The button does not always engage the blade when loading, and you have to reinsert the blade several times to get it to seat properly.

Useful knife, difficult to load blades
The convenience of the folding knife is nice, and the construction is sturdy. I decided to get one of my own after using one a friend had. Its “rapid change” blade change is a joke. In the end I had to disassemble the knife to load it as the quick load button did not work as intended. Hopefully they improve this feature in the future.

Quality heavy duty knife
This knife is very nicely built. Good heavy duty construction. Read some of the reviews after I purchased my knife. On the back of the display card it tells you where to tear to separate the knife and the card. You may actually need to cut it there because it seems they used a mylar strip so it is not too easy to remove the card. These days if an item is not nailed to something, it must be free, right. For blade removal, you must extend the blade fully, no slot visible in front of the slide button, so the black button on the left side lines up with the retainer to push it out of the way to release the blade. If the blade is not fully forward, things don't line up correctly. To insert a blade, you need to accurately line up the blade top to bottom and side to side to slide it into place. This is a well crafted tool, you don't have 1/4 inch of play like a cheap knife. This is a very nice product.

I bought this awhile ago and never use it, because it is a pain to change blades.
You have to press the button hard, then fiddle with the blade,wiggle it side to side, pull and curse. Then maybe it will come out. Buy something else.

This is an easy to use, well built product. It's very comfortable to hold. Changing the blade is as simple as pushing the button. I don't get some of the other reviews, but I suspect if they can't figure out how to easily change the blade, they probably shouldn't be using a utility knife!

I can see where the other reviewers are coming from about poor instructions for initial setup. There are some small images on the front for inserting new blades and text on the back about how to remove the knife from the packaging but it still took some trial and error to figure it out. Used it to cut carpet and underlay. This is the first time I've purchased a premium utility knife and it was well worth the money. Comfortable, well constructed and holds an edge. All around great knife.

Piece of junk
Bought one in the morning and it’s in the trash this afternoon. One can’t put a blade in this thing. Even after watching the instruction video.

Difficult to take out of packaging
I bought the DeWalt Retractable Knife (DHHT10046. You have to undo two screws in order to extract the knife from the packaging. Heaven help you if the internal parts fall out because there is no diagram showing you how to put the parts back together. I'll probably take it back to ACE Hardware where it bought it to see if they can put it back together. Not sure yet if I will keep or like to use the product.

Can't remove blade
Blade release mechanism didn't work reliably out of package and got worse over time. Currently won't release blade at all. Poor design. Do not buy this product. I have many Dewalt products that work well so this is a disappointment.
