Stanley Knife
Comfortable to use. Easy blade storage. Could be easier to change out blades.
Cheaply made, the blade pulls out
Great product
One of my favorite utility knives I have worked with over the years
Stanley Utility Knife
Great knife and ergonomic shape. I would recommend it without reservation
great utility knife
I like the blade storage and ease of loading new blade. I had been used to the antique kind you had to unscrew!
Avoid this piece of chit
When it's brand new the blade change out is great. After using it, not exposing it to any corrosive elements, it becomes a giant piece of chit when trying to change the blade out. Don't buy this product. Avoid it.
Poor Design
I have 2 of these and it is difficult to load the blades and Stanley does not have any instructions on line.
Easy and comfortable
I've owned a couple of them for over a year and they have become my "go to" Utility Knife. Unlike many reviewers, I have *NOT* had problems with the blades sticking or not holding. Loading and unloading is easy. I find when you load a fresh blade, if you wiggle the blade back and forth it will confirm that it is properly locked in, if the catch isn't fully engaged, the rocking motion will engage it.
Good control
I bought this knife because I liked the extra blade storage. I use it frequently when I want to insure a good grip. The ergonomics are good. The handle is designed well to prevent slipping. The blade change is a bit clunky but once you get used to it, it's not a problem.
Great Utility Knife
I picked up this utility knife at my local hardware store on sale. The knife itself is comfortable to hold. I really like the on-board blade storage at the rear of the knife so that I don't have to stop what I'm doing to find a new blade. The only issue I had with this utility knife is that I found it a bit difficult to push in the red button at the front of the knife and to also change the blade. I have another utility knife by a different manufacturer that has the same blade changing mechanism and is much easier to push the button, slide the blade in, and release the button locking it into position. Other than that, I think it's a great utility knife for the sale price I paid. It's so much better than the old utility knives where the blade would not retract, no on-board storage for new blades, and having to physically take the knife apart to change the blade.
Easy to use
Just picked one up this week! Works just like it should. Really easy to load compared to others I’ve used.
Blade insertion is unreliable
Blade keeps falling out or will not completely retract. Taking knife apart to insert new blade is laughable. Thank goodness I kept my old standard Stanley knife.
Can't get blade in
Tried and tried and could never get the blade in. Squeezed the heck out of the red button. No use.
Easy Blade Change - Now that I know how!
Haven't changed the blade since I bought the knife but then... I kept looking till I found a Ytube video on how to. Obviously, it's easy to pull the blade out simply by pushing the red button and letting the blade fall out. I was jaw-dropped when I saw the guy simply push the new blade in till it locks! THAT is how easy it is to change the blade. You do not even need to depress the red button, just push the new blade it till it locks (might need a jiggle or two. Yes, should have included that instruction. It is the easiest blade change of any knife. Glad I was not the only who struggled :)
Can’t beat Stanley priducts
Solid design and performance
Don’t bother.
I’ve spent more time putting the blade back in than getting work done. Even caulk will pull the blade out of the holder. I wanted it to work, but it doesn’t. Bought a Dewalt today.
Gman is happy!
It's hard to find a good working comfortable utility knife at any price. Aubuchon's has this model that is and I found had it for the lowest price of anyone! The comfortable grip, extra blades compartment and quick changing if the blade are all what I was looking for. No screw diver required. The yellow color makes it easy to find while working and laying it down in several different areas.
Over engineered, no useful instructions
Take a simple utility knife, make it bulkier than it could be, use star drive screws instead of "normal" screws and don't provide info on use and trouble shooting instructions and this is what you get.
Great Product
A great product and easy piece of equipment to use. Despite the other comments on this page the blade is so much quicker and easier to change and use than other knife products
Cannot insert blade
I have had same problem as the other reviewers. The red button will not push in so you cannot insert a blade. I called customer service and they could not help. I will take back to store where I purchased it and see if they can help. Company should be looking at their reviews and fixing the situation.
Works fine.
The blade is easily put in by pressing a red button on the side, if you don't lock it propperly in place it will fall out, but if you have half a brain you can figure out how to use the knife in 5 minutes
Had to take the knife apart....
This thing made me take it apart to take the blade out and then I saw how to load it. Be ready to take out the two little allen screws on this thing.
Works like it is suppose to
I am happy to find this knife that performs like it should
