Marc mccarragher –
Un très bon produit cela fait plus de 30 annee que j’ai acheté mon premier et que j’utilise encore
FG –
Very sharp and strong
PB –
I somehow misplaced my other one so this is a replacement. It is sturdy and fits well in the hand. I haven’t had any of the problems reviewers have had.
Michael Crowe –
Very ergonomic and super easy to switch out the blades. I use these in all my shipping hubs and wouldn’t use another.
CQCoder –
I’m a huge fan of these blades. This is an update to their original silver model and, thankfully, is an update without one of those ‘crap, why did they remove that’ feelings.
I love these because the blades are sooo easy to change. I can’t stand a dull blade and having to stop and unscrew them to change this is simply annoying. Here, a quick press and you can reverse the bald or swap in a new one.
I also like the grip and the built in blade holder.
I purchased three of these and did run into a quality control issue on one of them. Removing the blade was very difficult and I couldn’t insert a new one. I took it apart to see if I could fix it – the frame that holds the blade was just a bit too tight to let it slide past and lock in. I tried prying it wider but finally just game up and toss the bad one.
I’m hoping this is just a glitch and not something that has happened in redesign. I’ve given these gifts in the past – gone through probably six of them with out a bad one (the older style).
MR P PARNELL –
A classic tool. Great quality and performs as expected.
PK –
Loved it while it worked. But the blade for some reason went inside and not able to slide it out. So now totally not usable. Ended buying another Stanley snap off blade cutter.
Cris Gonzalez –
gets clogged with dust & jams easy
John Thoren –
Removing the packaging is the only downside – it’s ridiculously difficult. Blade changes are a snap with this, but you have to read the directions – it’s not like any other utility knife. It feels great in your hand. A touch of grease applied to the blade sliding area on the inside, and it works very smoothly.
Lauren Kiernan –
Great knife. Easy to seat the blade. Love the handy blade storage in the handle. Just moved house and this is making opening boxes a lot quicker and smoother.
Big Tex –
Fat and cuts through like butter. Very sturdy.
Amazon Customer –
As an artist I use this for many projects and I won’t ever be without Fat Max
Mc2128 –
Terrible product. When pushing the blade advance button the blade carriage would rock in it’s track in the knife body and lose it’s tracking. As a result the tip of the blade would jam on the inside edge of the blade opening of the knife body. You have to push and wiggle around the button and/or push it back and forth to get the blade to advance. Over all resulting a delay in using the knife as intended. In simple terms, you have to mess with it to get it to work. I eventually took it apart and filed a section of the body to make a sort of ramp so the tip of the blade wouldn’t jam while trying to advance the blade.
That somewhat fixed the issue. Now instead of the blade being jammed 90% of the time it jams 30% of the time. I think the noob designer(s) of this product needs a through dress down. Perhaps Stanley has lost sight of who they are and the principles they were founded on. It seems to me they have designers working for them that are more into having a product look “cool” then one that functions reliably. I suggest Stanley start making it mandatory that their designers actually be experienced in utilizing the tools they are tasked with designing. Because I feel it’s evident the team that worked on this knife have been wrongfully collecting a check from Stanley under the false pretenses that they had any talent, common sense, or understanding of tool and die making.
