OLFA 25mm Extra Heavy-Duty Utility Knife (XH-AL) - No-Slip Grip, Auto-Lock

I’ve been asked where I got this utility knife several times after bringing it to work, and it’s easy to see why. The build quality is excellent, and it cuts through thick cardboard, plastic wrap, and other packaging materials with ease. I’ve been using it regularly and have only had to replace the blade once after it naturally became dull. One of my favorite features is the size. It has a comfortable grip that feels secure in your hand, giving you better control and allowing you to apply more force when needed without feeling awkward or uncomfortable. The retractable blade and locking mechanism are also standout features. The blade extends and retracts smoothly, locks securely in place during use, and folds away safely when you’re finished. Those features make it both convenient and safe to carry throughout the workday. This knife stays sharp for a long time and makes quick work of everything from heavy cardboard to plastic wrap. The blade replacement process is simple, and replacement blades are easy to find. The ergonomic grip and smooth blade operation make it comfortable to use for extended periods. Whether you’re opening boxes or breaking down packaging, it feels natural in the hand and is easy to control. Considering the build quality, durability, and performance, this utility knife offers excellent value. It feels like a tool that’s built to last, making it well worth the price for anyone who uses a utility knife regularly. Overall, this has become one of my favorite tools for work. It’s durable, comfortable, reliable, and performs exactly as you’d expect from a quality utility knife.

Yes, this looks like an OLFA because it is! After checking out many knives of this sort and reading many reviews, I took the plunge on this 25mm version. No regrets. It's a superior performer and built very well. The blade lock has a nice solid positive locking set and feel to it. Retraction is smooth and there's no rattling. Blades are easy to change. The grip is superb wet or with gloves. I wouldn't recommend this size for a small hand as the body is robust, which also puts you in command. It's hard to go wrong if this is the style of knife that fits your needs.

I hesitated on this "box cutter" because of some reviews that complained about the slide latch not holding. But I figured different strokes for different folks, right? This boxcutter came with a heavy duty blade, and was a fit for blades I already had. I've cut cardboard, drywall, plastic and thin wood. The latch hasn't slipped once. I like the fact you can just snap off a blade section and keep on cutting. This blade has served my needs in the best way. So construction is excellent, function is spot on, the slide latch is excellent and locks well, the blade quality is sharp and heavy duty, and value for the money is excellent. If you want a sharp and simple cutter, this is the one. I recomment this as a buy.

I have bought a number of Olfa knives recently from Amazon, in a variety of sizes, and I am impressed with all of them. For years, I used either an X-acto knife or one of those knives with a retracting blade where unscrew it and take it apart to change the blade. These Olfa knives are much better. The knife with the retracting blade was annoying because the blade had a tendency to retract when you applied too much pressure on the blade and sometimes it was hard to slide the level for extending or retracting the blade. The Olfa mechanism is solid and keeps the blade in place but moves easily when you want it to. It moves with a satisfying click. When the blade tip gets dull, you can take some pliers and break off the tip as the blades are perforated, so you get a fresh tip, which means the blades can last for a while. These Olfa knives are very satisfying to use.

The "ginsu" knife really is the way to go for a utility knife in construction. Having the extra blade length means you can saw through deep material and do flush cuts. However, I had to return it because the thing is so big it doesn't fit in my bags or my pockets or anywhere. Even the slim model has a grip that's a little too wide and 'grippy' to pull out of my tool bags and put back in, I was fighting it all day. I've used the BeWalt equivalent for years, and it's a little janky now. So I went for the upgrade and this felt better made, but it takes up too much space. It's also plastic and the BeWalt is all metal. The locking mechanism does feel very nice on this one though; much better than the BeWalt. Try the H-1 I liked that model more than this, but still returned both. If you're leaving it on a bench or in a drawer it's perfect.

I have several Olfa utility knives. The handle on my “decades” old original 1” started to crack. Slide lock is much easier to use but wheel lock works OK. Super sharp black blades are the best. Highly recommended.

This knife cause me to rethink all my assumptions about the usefulness and viability of using a box cutter over a razor knife. First and foremost is the thickness and width of the blades themselves. The knife fits well in the hand, is easy to find in the tool pouch and best of all - you don’t have to stop to change a blade - just take your linesman’s and break the current tip off. I still have my razor knives and blades, but they are idle and have been so since a few days after the Olfa’s arrival. This is the single greatest utility knife I have ever used…If it wears out (and so far that doesn’t seem likely), I will definitely buy another one!

Works great! Well built and sturdy. Excellent for large hands and heavy cutting.

la lame manque de coupant je ne comprends pas pourquoi, le cutter reste excellent

I have used all types of cutters, Stanley etc and none of them are equal to the Olfa. Solid build with easy to use blade adjustment. They offer a range of blades and they are all sharp enough to cut through thick materials with ease.

All I can say is wow! I did not know utility knifes had such a quality ceiling. What a time to be alive.

This is ridiculously sharp. Which is safer in the long run as you don't need to hack away at things and use excessive force thereby slipping and cutting yourself. Being this sharp, it also encourages a healthy respect in use. Nice grippy rubberized handle which is very easy to maintain a grip on. Mostly used for opening full packages and dismembering empty cardboard boxes. It's sturdy enough you could use it for cutting up old carpets or whatever. It's of the type that you index out just the amount of blade you need then when that bit goes blunt you can snap it off and dispose, indexing out the next section of sharp blade until you run out and replace with an entirely new one. Amazon also sell the replacement blades at a decent price.

It's great. Heavy duty with grib. Worth the money
