Zero Tolerance provides a dark, refined alternative to the original 0450 with some extra flair.

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.

As an extra visual touch, ZT has added two emerald-green anodized-aluminum tube spacers that are especially eye-catching, standing out against the black handle. The 0450CF takes advantage of ZT’s KVT ball-bearing system to enable smooth, easy opening for either left or right-handed users. A left/right reversible, deep-carry pocket clip rounds out the 0450CF’s basic feature set.

While it’s a smaller, more gentlemanly knife, the 0450CF proudly lives up to the overbuilt standards for which ZT is well known.
