Olfa18mm Heavy-Duty Utility Knife (MXP-L) - Multi-Purpose No-Slip Grip Precision Knife w/All Aluminum Handle & Snap-Off Blade, Custom Cutting Depth, Replacement Blades: Any OLFA 18mm Blade

I have had their L-1 18mm ratchet for 2 years and love it. Once I found out OLFA made a die-cast Aluminum unit, I had to have it! The way this unit feels in your hand screams quality. It can be used for light applications to very hard applications. With that said, if you are going to use this knife under heavy load, I would suggest getting the ratchet version. You can really crank the wheel down and make sure the blade is secure. Lastly, buy the OLFA BLADES.... please. I spent $20 on another brand and cut cardboard and it was painful. I swapped back to the OLFA LBB 18mm Ultra sharp heavy duty blades for $29 and its was way better. Night a day difference. Totally worth the 9 bucks more and you get 50 blades. The OLFA blades also come in silver if you want to save a few bucks and not get the black ones. LB is the Silver Blades and LBB are the black blades.

A utility knife that gets the job done in tough conditions. Simple design and easy to handle. Beautiful to hold and use.

OLFA knives are known for being well-made, sharp utility knives and this example is no different. It is designed to be tougher than some of their other offerings. With its aluminum housing, it seems to be strong enough to handle some hard use while still being comfortable in the hand- that is, if you're right-handed. For having a nearly symmetrical design, there is no option to reverse the blade for left-handed use. This means southpaws end up with the wheel lock digging into your palm and a less secure grip. Being Left-handed myself, I took a chance on this knife mainly due to OLFA's reputation and found that in less than 5 minutes with a nail file, this utility knife could be made to accept flipping the blade over for use with the left hand. I've included a picture of the area filed down and, for such a small modification, it's a shame that OLFA doesn't offer this knife for both right and left hand use straight from the factory.

Great utility knife. Super sharp if you get silver blades. Use it for everything. A pleasure to use. Japanese quality always amazing.

Like lots of tradesmen I made the switch from utility knives to the snap blade ones a long time ago…don’t get me wrong …you still need a good quality utility knife for lots of jobs but this is the knife that should always be on your tool belt.
