Understanding the Zero Tolerance 0990 Flipper Knife

The Zero Tolerance 0990 series is a streamlined version of the legendary 0999 concept knife, offering a high-performance skeletal design that is optimized for everyday carry. These knives utilize premium CPM-20CV steel and a unique floating backspacer to balance aggressive aesthetics with practical utility.

What type of blade steel is used in the Zero Tolerance 0990?
The Zero Tolerance 0990 series uses CPM-20CV stainless steel, which is known for its excellent edge retention and high corrosion resistance. This makes the 0990 an ideal choice for users who want a blade that stays sharp through extended use in various environments.
How does the opening action and locking mechanism work?
The 0990 operates on KVT ball-bearing pivots for a fast and smooth flipping action. While many Zero Tolerance models use frame locks, the 0990 series features an inset liner lock, which allows for a full carbon fiber overlay on the handle scales. You can learn more about these different systems in our guide to folding knife lock types.
Is the Zero Tolerance 0990 a heavy knife?
No, the 0990 is relatively lightweight for its size, weighing in at just under three ounces. The use of carbon fiber handle scales and a skeletonized structure, including a pass-through behind the pivot, helps reduce weight without compromising the strength of the knife.
What makes the 0990 design different from the original 0999?
The 0990 is a more compact and accessible version of the 0999 concept knife, designed to be more affordable while retaining its iconic look. It simplifies some of the original's complexity by using a steel overlay instead of titanium and an inset liner lock, bringing the price into the $240 range.

Does the 0990 series support left-handed carry?
Yes, the Zero Tolerance 0990 includes a deep-carry pocket clip that is reversible for left or right-hand carry. While the handle features a steel overlay on the front side that makes it look asymmetrical, the clip can be moved to the opposite side to accommodate southpaw users.
