- Reviewed in Canada on October 5, 2014Verified PurchaseThis is the prefect utility knife for my needs. I like this knife so much, I bought two!
I often use the blade while extended, so I need a knife with the snap-off blades rather than the smaller double ended blades. I've used the auto-loading knives, those which hold a number of blades in the body of the knife so the blade can be changed quickly simply by ejecting the old blade and then loading a new blade by sliding the blade lock back to pick up a new one. These knives, while seemingly ingenious in design, and ubiquitous in their popularity, are troublesome, at least for me. I've owned three or four of these and every one has broken down in one way or another over a rather short period of time...and they aren't cheap.
One commenter noted that the EHD Utility Knife requires too much time and effort to unlock the blade to extend and retract and while I'd agree it requires more time and effort, if one were to add up the time wasted getting those auto-loading knives to work properly, the time and effort saved with this knife would be easily apparent...there's almost nothing to go wrong.
Specifics, to fill in where 鶹's terrible product descriptions fall short. This knife uses the 25mm snap-off blades. These blades are larger than the more popular 18mm blades. The knife action is simple. The knife holds ONE blade, the user turns the locking knob counter-clockwise in order to move the blade in or out, then turns the knob clockwise to lock the blade in position. To change the blade, simply loosen the locking knob as described and pull the knob and blade out the back of the knife handle. Insert a new blade, attach the locking knob assembly and continue using the knife.
- Reviewed in Canada on November 19, 2020Verified PurchaseThis is my favorite utility knife. I love the weight and sturdiness of it. It is well built and comfortable to use. I won't keep anything else in my toolkit. I bought my first one years ago and used it very thoroughly. I even bought multiple packs of replacement blades and went through them. Sadly, it was stolen recently so I had to purchase another. If you are looking for a good quality utility knife, you don't need to look any further.
- Reviewed in Canada on July 13, 2017Verified PurchaseI use it all the time at work for cutting drywall and carpets etc. The 25mm blade is a lot sturdier and forgiving than the regular 18mm blades. I used ofther brand's offerings such as Stanley's and this one came on too by far, my only complaint is that you need to really tighten the screw if you're going to be cutting through touch things like drywall.
Would reccoment do any professional that needs a good utility knife for heavy duty use.
- Reviewed in Canada on August 28, 2020Verified PurchaseThis replaces my older different branded knife where the locking feature broke. This is just as good. I prefer the 25mm over the 18 as it can handle tougher jobs.
5 stars as it makes me feel tough as I cut through cardboard boxes to put them out for recycling. Paid regular price for item and recommend after initial use.
- Reviewed in Canada on July 22, 2019Verified PurchaseGood heavy duty knife
- Reviewed in Canada on November 1, 2019Verified PurchaseA rock solid work knife. Definitely strong for a utility knife. Well worth the price. Good fit and heft.
- Reviewed in Canada on December 28, 2023Verified PurchaseMore expensive but you get what you pay for. Blade locks tight.

Reviewed in Canada on May 19, 2020Verified PurchaseJ'ai essayé plusieurs couteaux utilitaires et j'ai conclu une chose de mes expérience : Les Olfa sont les meilleurs. C'est simple, si c'est pas un Olfa, ça ne marche pas. Soit la lame est lousse, soit c'est l'enfer de resserrer les morceaux ensemble, soit la prise en main est mauvaise. Bref, Olfa corrige tous ces problèmes en offrant un produit de qualité. Oui, il est un peu plus cher, mais vous en serez tellement plus heureux de travailler avec le bon outil!
Note: Le couteau est assez large, donc avoir de grandes mains peut aider dans le cas de ce produit.

5.0 out of 5 stars Better hand ergonomics
Verified PurchasePurchased June 2025. MUCH better to grip than the other Olfa 1 inch (25mm) knife, the H-1. Even if you have smaller hands, it's better, trust me, I own both. It's not cheap at $20US. If you're doing fine work, like upholstering a car stereo speaker pod or something delicate requiring exacting or tiny, precise cuts don't use an Olfa, get Heavy Duty single sided razor blades for finesse work, use this Olfa when you've got to put some muscle into it & you need the rapid blade snap-off feature to get a fresh tip on the fly. Wear safety glasses when snapping off a section.
