Customers like the quality of the utility knife. They say it's solidly built, works well, and will last. The 99E has a stout solid feel, and is one of the best brands on the market. The shorter and thicker blade is much more resistant to lateral forces, and despite using it with no spare blades, it'll still cut straight along the markings.

Customers are mixed about the ease of assembly of the utility knife.

"...how well defined the different blade positions are; there's no wasted time fiddling with it to make sure your blade is locked in place...." Read more

125 customers mention75 positive50 negative

However, others say that the blade could not be slid out of the product like you would, the lock stopped working, and that the knife won't emerge.

"...sure everything was lined up correctly, it still was very hard to extend and retract the blade. I thought Stanley made a better product than this...." Read more

"...I like that it is retractable, so I can keep it in my tote with my scissors, stapler, cable cutters, etc...." Read more

37 customers mention10 positive27 negative

Customers have issues with the ease of opening the utility knife. They mention that it is difficult to open, has a tricky screw, and the 3 blades are inside, making it difficult to use. Some customers also mention that the box was open at the end, making the knife more susceptible to falling out of the box.

"...The screw was very hard to open and one blade was already in place and there was only one on extra side, yet ad said there would be 3 blades...." Read more

"...It was a struggle to get it open but afterwards it screwed in and out easily... it was like the screw may have been crooked originally...." Read more

"...The blade mechanism is convenient, smooth, and more robust than the Stanley 10-499. Even the screw that keeps it shut is good quality...." Read more

"...it's very resistant to being "opened" (having the blade pushed out), and once it's out all the way, the blade won't go back in...." Read more

What started this whole foray into box knife utopia for me is the 99E at work got taken off some where, I took in my 10-499 from home and it drove me nuts with the rattling and blade setting not staying where I put it.Figured why not get the Pro. Pro is too big for my pouch (but not for the workshop peg board at home ) and I use the short blade settings all the time (see comment on Pro bellow ) so I ordered another 99E because I knew I liked it. If they had cheapened the knife I was all set to order the Milwaukee with the blade advance on the side but I don't need the bulk so since the 99E is still very well made I am all set.The 99E * has a stout solid feel * rattles if spare blades are in it but not nearly as much as the 10-499 A small piece of foam stops the rattle. * has five VERY distinct blade settings. * has the firmest button spring for the blade settings. * super easy to feel the blade setting notches * They added some thing to cause friction to hold the screw for opening the case so the screw won't rattle loose. That was a nice touch.The 10-499 * is the lightest by far but strong enough * I find that how ever I grasp it the button gets pushed and the blade advances to the longest setting while cutting up large boxes (many bicycle shipping boxes ). * It rattles a lot * Three blade settings with a slight extension on the forth but that is to remove the blade using the side blade release button.The "Pro-Grade" * It is a very substantial box knife * It is "defend your castle from invaders" substantial (if it is a small castle and there are only half a dozen invaders ). * As you can see from the photo it is way larger. If you are wearing gloves and can't hang onto a smaller box knife the Pro is made with you in mind. * When I slipped it into my small tool pouch on my belt I was concerned with how much room it took up and it is heavy. * The blade changing mechanism works really , really well. Never a snag. Just run the thing back after pulling out the worn out blade and it grabs and advances another blade as you run the button forward again. * This knife comes with eight blades ! ! ! The 99E comes with three. * ONE small problem . . . the spring for the blade advance setting lock is very weak so it is hard to tell were the notches are. It takes a knack and practice to even find one consistently and it is not quick. For the most part this knife will be used with the blade fully extended so not a big deal. Once in a notch it stays put.There is a metal flap spring with a coil spring reinforcing it that pushes against the side of the spare blades to hold them tight against the self loading feeder. This seemed to effect the blade advance lock so I used it with only the one blade being used. Still hard to find the notches. * There are three blade settingsThe photo shows the minimum setting for each blade. A bit longer on the Pro than the rest.
