Zero Tolerance: ZT0566 - ZT Hinderer


Zero Tolerance Knives and Rick Hinderer team up again to create the new Zero Tolerance 0566. More compact than its larger brothers, the 0560 and 0561, the new 0566 is built for pure performance in an EDC-perfect size.

On the performance end, the blade is pure CPM-S35VN powdered steel. With almost no impurities in the steel, the 0566’s blade can be sharpened to hair-popping levels—and also offers excellent edge retention, strength, and toughness. For a secure grip, the front scale is textured G-10. The back is all stainless steel with a sturdy frame lock and lockbar stabilizer. The 0566 offers Zero Tolerance's quad-mounting system so users can choose tip-up/tip-down, left- or right-handed carry. And because it's a deep-carry clip, the knife will sit comfortably deep in the pocket.

For Rick Hinderer style in an easy-carry size, the new 0566 fits the bill.


  • Made in the USA
  • SpeedSafe® assisted opening system
  • Frame lock, lockbar stabilizer
  • Quad-mount (tip-up/tip-down; left/right hand), deep-carry clip


 Blade Steel:    CPM-S35VN, stonewashed finish 
 Handle:    Textured G-10 front, stainless steel back 
 Blade Length:    3.25 in. (8.25 cm) 
 Blade Thickness:    0.156 in. (0.396 cm) 
 Closed Length:    4.45 in. (11.3 cm) 
 Overall Length:    7.70 in. (19.6 cm) 
 Weight:    5.4 oz. (150.3 g) 

The 0566 is the perfect compromise of compact size, durability, and comfort.

By reducing the size just enough from its predecessors, ZT has struck the perfect balance. The stainless steel construction and robust locking mechanism maintain a feeling of beefiness without taking up quite as much room as the larger Hinderer models.

The 0566 blade is CPM-S35VN powdered steel, a highly refined steel which is formulated to have great edge holding, toughness, and stain resistance. The blade opens on ZT’s SpeedSafe Assist system, a spring-assisted opening that launches the blade open once you push on the flipper tab.

When open, it is totally secured thanks to the built-in framelock. The blade has no play, and the lockbar has no unwanted lock-stick. Thanks to the integrated lockbar stabilizer and a stainless steel lockbar insert, ZT has ensured that this knife will keep functioning just as well as it does on day one. It's built to withstand a lifetime of use and remain totally dependable.

The corners of the handle are chamfered for relief and comfort, and strategically placed jimping (grooves) on the front and back of the handle add even more grip to the ergonomic design. The end of the handle sports a built-in lanyard hole and a deep-carry clip that can be carried on the right or left side.

Zero Tolerance is filling an important spot in the knife industry with knives like the 0566, making a high-quality and totally accessible version of a custom maker’s ingenious design.

    Heavy duty EDC.

    Posted by Cameron on 24th Apr 2014

    I have the bigger version of this knife, which is a thing of beauty. It has a titanium frame and an ultra smooth unassisted frame lock. It also cost $260. But I found it to be too large for an EDC, being a 4 inch blade. So I ordered this model as soon as it came out, expecting the same knife, only smaller (3.25in). It is different in a couple of ways. The flipper opener is assisted, which I tend not to like since it makes the knife seem aggressive. However, it has worked well. The frame seems to be made of steel, rather than titanium, so it is much heavier for its size. That probably accounts for the large price difference. It was sharp when it came, but it had a really heavy grind, that I felt needed changes, so I convexed it, which made a world of difference. I know it is usually a bad idea, but I really felt it needed it. I have been using it hard on remodeling, scraping adhesives, wood, plaster etc. I even have been intentionally abusing it a bit and it is just fine prying paint cans open. It's a brute. I actually hammer brads with the frame. The Elmax is great and really does take a wicked edge. Overall, tough, heavy, great steel, but needed some lovin up to get hedge I needed.
