The Zero Tolerance ZT 0561 is an extreme duty knife. The ZT0561 would be a great pocket knife for anyone needing a large, rugged folding style knife. Due to its 3.75" blade, pocket carry can sometimes be cumbersome. However, the knife does come with a pocket clip that can be located in any of four locations. The knife is fairly light for its size, coming in at 6.4 ounces. This weight is made possible by one whole grip of the knife being made from titanium. The other grip panel is made of G-10 in flat dark earth. Both grips are textured with, what ZT calls, a "3-D machined," which is a type of scallop pattern and gives the knife a good texture to hold on to. The blade is made from an "Elmax" powdered steel, which gives the knife good corrosion resistance and good edge retention. The blade runs on a set of ball bearings for smooth operation with an easy opening tang on the back side of the knife. This knife would make a great addition to anyone needing a tactical folder that might get abused.

NOT A KNIFE..... IT'S A BEAST!

This edged weapon is something to behold. I've owned benchmade, kershaw, spiderco, ect.... This thing will be my last knife I'm sure. It holds an edge and looks good doing so. I've used mine for work and play and will never buy another cheap piece of junk knife again. You get what you pay for!!!

Outstanding Knife

After purchasing this knife, I have officially laid my Benchmades to rest. This is an absolute quality knife. The lock is rock solid and there is absolutely no play in the blade. The handle is very comfortable and grips the palm extremely well. I love how the flipper acts as a finger guard while open. The size is very intimidating at first for an EDC, but it is surprisingly thin and fits in the pocket well. The blade is incredibly sharp and super stout.

The Spyderco Persistence is the second smallest knife in Spyderco’s budget folder line. It’s got a blade length of 2.75” blade and an overall length of 6.8” while open. It has a 4-way clip that can be positioned for left or right-handed carry and tip-up or tip-down carry. The blade has a very large hole positioned just right for quick opening. The G-10 grips and skeletonized liner keeps the knife relatively light. The blade was very sharp out of the box and seemed to keep a good edge for a while. The width of the Spyderco knife helps fill your hand very nicely and is easy to control. The knife locks with a liner-lock that is easily released with the thumb of your hand and (with care) allows you to close it one-handed. This is a great, inexpensive knife that I would recommend to anyone.
