Zero Tolerance 0450CF Knife Review

Zero Tolerance 0450CF Every Day Carry

Zero Tolerance 0450CF Knife

Manufacturer: Zero Tolerance
Model number: 0450CF
Weight: 2.45 oz
Over the years I’ve tried lots of different “every day carry” knives and I’ve not found many that check every box. However, about six months ago I started carrying the Zero Tolerance 0450CF Knife and it’s easy to say my favorite EDC knife to date. It’s a lightweight, compact knife with an excellent edge.

This sophisticated ZT is a smaller option in the ZT family, yet offers a robust combination of durable, premium-quality materials. The blade steel is CPM S35VN for exceptional toughness, wear resistance, and edge retention. The S35VN blade is DLC coated for matte-black good looks and enhanced performance. The front handle scale is carbon fiber, balancing the knife’s solid construction with lightweight convenience. The DLC-coated titanium back handle offers a secure frame lock—so you can always cut with confidence.

Lightweight and Compact

For my job as a project manager and construction supervisor I’m in and out of the truck all day running between the office and construction projects. So my preference for an EDC knife is something lightweight and compact. I want a knife that holds an edge without needing constant sharpening and a knife that can tackle most small to medium cutting applications.

As you can see in the adjacent photo, the 0450CF is pretty slim for a blade measuring just over 3″. Because of how slim it is, I find it makes a great EDC that doesn’t make pants pockets feel bulky and the knife doesn’t catch on when it’s tucked into my pocket.

In addition to be slim, the carbon handle is extremely light making me forget the knife is in my pocket compared to larger, heavier EDC knives I’ve tried before. It weighs in at just 2.45 oz!

The belt clip is also slim (really meant more for clipping inside a pocket in my opinion) and doesn’t on things easily.

Excellent Edge Retention

I’ve been extremely impressed at how well this knife holds and edge. As I said before, I’ve been carrying this knife approximately 6 months and just recently sharpened it for the first time. That’s pretty impressive considering I use the knife daily and I’m not shy about what I cut with it. From cutting open boxes to strapping material and even using it in the woods while hunting.

Overall Impression Zero Tolerance 0450CF

While not as beefy as some of the ZT knives I think this is a perfect size for EDC, especially if you’re not cutting with it all day. The ZT 0450CF is a lightweight, compact knife with a great edge and a great look. If you’re looking for an excellent knife with a long lasting edge and compact size I highly recommend this one!
