NT CutterHeavy-Duty ABS Grip Screw-Lock Utility Knife (L-500P)

It's the quality and sharpness. Twenty times better than any snap off knife in the box stores.

Maravilloso y funcional para lo que está diseñado.

18mm Snap off utility knifeThe quality of this utility knife is exceptional, Japanese are really skeptical about what they're doing. I love it!, all metal construction except only 2 things! Although this knife is great it could be much more better IF ratcheting lock wheel knob should be metal too but it is plastic, and the blade snapper is also Plastic as well but the rest of the knife are all metal. Overall it's a great knife, great quality Japanese made utility snap off knife versus the Chinese imitations, copied and replica ones. One thing for sure! I have to use and abuse this knife to find out if it last! My 17 year old Japanese made retractable utility knife is still working though but it's not a snap off like this one. I highly recommend this cutting tool. ⭐⭐⭐⭐⭐

With my old go-with-the-cheapest box cutter on its last legs/blades, I decided to shop around for something a bit nicer to replace it just in time for moving into a new apartment. The NT Cutter wasn't much more expensive, but it sure as heck was a lot nicer.Since getting it a few months ago, it's been through some brutal box and packing tape cutting, including really hard multi-ply corrugated cardboard boxes that held appliances and heavy furniture -- and even the dense sort of boards that protect furniture corners (for which I probably shouldn't use a box cutter). For the vast majority of boxes, it slices through like butter, never catching or tearing except on the gnarliest packaging. The edge has certainly started to visibly wear by now, but its performance for my purposes is largely unchanged (especially now that I've gotten through the move in large part).The size is perfect for my small hands, and I really like the clicky extension/retraction -- much smoother than my old box cutter.Really happy with this knife, and would be glad to keep refilling it with blades.

This is the best snap-blade utility knife that I've used. Funny, yesterday I was discussing how much I like this tool with a friend over lunch. My friend said that he really likes the Lennox Tradesman Locking Utility Knife, also sold by Amazon. (When I remember how to link to Amazon products within the page I will update with the link.) We have different needs: he owns an HVAC company and puts his knife to heavy use. Professionally, I am an electrical engineer and my hobby is woodworking. I also use the Utility Knife for home projects. My friend needs a strong blade; sharpness is less critical for his purpose. I need a sharp blade; there are different tools I use for heavier cutting.Pros-------------------+They mean it when they say "Locking". Unlike other utility knives I've used, the blade will not slip in this one.+Integrated blade snapper. The red plastic end-plug has a slot the fits over the blade tip like a shoe, covering the point and exactly the right depth to snap off the old blade.+Feed good in the hand.+Stainless construction.+Easy blade changes.Cons---------The blade snapping slot in the red plastic end plug could be marked so that it is easier to see: I struggle to see a <1mm slot in red plastic in anything other than bright light. Usually, I mark it with a Sharpie.-The gray color looks cool, but makes the tool more difficult to find inside my tool bag.Comparison---------------At this same time I bought the NT Utility Knife, I also bought an OLFA 5003 L-1 18mm Ratchet-Lock Heavy-Duty Utility Knife, also from Amazon. This blade will stay locked, but only after you take several turns on the thumb wheel. They use interchangeable blades.

The blade holder does bend if you drop it tip down.

I've purchased 2 of these because I was impressed by the quality of the first one. These are made in Japan, super sharp, and well put together. If you need a good, solid sliding utility knife and want to support first world countries, this is the ticket. NT cutter often gets overshadowed by OLFA here in the states, but they are absolutely on the same level of quality.

I like them so much I ordered another 2!!!

... great product

One of the best cutter available for skilled jobs.

A little heavier than the Olfa L-1, and ever so slightly larger, but you'd expect a little extra weight when you move to a metal cutter from a plastic one. The NT Cutter doesn't feel any heavier when you're using it. The ratchet lock is just as nice as the Olfa. Super sturdy and I've put a ton of weight on it cutting outthick silicone between glass. This new NT Cutter weighs in at 104g and my old weathered banged up Olfa L-1 at 74g both with an identical brand new blade. The same crappy kitchen scales were used so use the weight given as a scale for comparison. I've used the NT Cutter for a few days now and I'm really happy with it. As good as the Olfa so far and so long as the ratchet is as good, and it does seem as good, I think the aluminium body may outlast the Olfa. It's also worth noting the ratchet piece from the Olfa L-1 fits the NT Cutter, although the ratchet piece from the NT Cutter is a tiny bit wider than the slot in the Olfa so it doesn't fit the other way. In summary, this seems like a really solid knife and a great alternative to Olfas L-1. Plus it looks very different so it's less likely to move to someone else's toolbag from your own...

I really like this utility knife as it is lightweight, made of stainless steels, though painted with a nice vintage look, and the blade locks to the location I'm using it without using a wheel.
