The Zero Tolerance 0230 Slip-Joint is the EDC knife to carry around in places where you usually wouldn’t carry a knife around.
A good friend of mine is part of the corporate world during the week. On the weekends, you can find him wandering around in the woods like some caffeinated spider monkey. In the warmer months, he splashes through the lakes and the streams. Now that the world has gotten back to normal, and he has to wear suits all week, it’s tough adjusting to life without a knife in his pocket.
Have you ever tried to hang a decent EDC folding knife off of a pair of dress pants? It might as well be an anchor. Besides, there’s a little bit of etiquette that comes into play in that scenario — office life, social mixers, speaking in large crowds – sober – without swearing; so you almost need something a little more buttoned up if you’re going to carry a knife around with you in those situations.
Enter the Zero Tolerance 0230 – an Ansø designed gem of a slip-joint knife made from carbon fiber and CPM 20CV steel.
Based on the perpetually sought-after Monte Carlo by Jens Ansø, the 0230 may harken back to the old days by the fact that it’s a slip-joint knife, but believe me when I tell you — this thing is VIP level in terms of modern. But what caught my attention was that the 0230 comes complete with a pocket clip, a recent upgrade Zero Tolerance made based on demand.
In short: The Zero Tolerance 0230 is a premium slip-joint pocket knife with carbon fiber scales and exceptional steel. Based on an iconic design, it’s a perfect blade for the dapper dresser in the urban world.

Design and Features
The 0230 is the epitome of opulence: carbon fiber scales with a blue, anodized backspacer, 20CV stonewashed Sheepsfoot blade, and a deep-carry pocket clip that allows the 0230 to disappear in your pocket without getting lost.
The whole package is less than 2 ounces and works in all environments. But it shines in an urban setting as slip-joint knives meet and exceed almost all knife laws across the world.
The blade on the 0230 is controlled by a ball detent on each side of the blade, as well as a half-open position. This keeps the knife closed until you need it but also keeps the opening and closing operation smooth over time and not just out of the box.
First Impressions
Not only is Jens Ansø an incredibly nice guy, but also a very gifted knifemaker. This shows in the Zero Tolerance 0230. It is a production version of his Monte Carlo, a knife you’d be hard-pressed to get your hands on. If you did, you’d find it ultra-premium and ultra-posh.
