Product Description

Product Description

In response to customer requests, ZT is proud to introduce the new 0350. It’s slightly smaller and slightly lighter than the 0300—10% to be precise—but just as aggressive. The 0350 is fully equipped with SpeedSafe® for one-handed assisted opening. Even in combat gloves, you can easily deploy the blade using the large, ambidextrous thumb stud or blade protrusion. The blade is S30V stainless steel with Tungsten DLC (Diamond Like Carbon) coating. S30V provides extreme durability, while the black Tungsten DLC is non-reflective, enhances hardness, and reduces friction drag. Textured, matte-black G-10 scales provide a secure grip. Includes a quad mounting system for tip-up, tip-down, left- or right-handed clip carry. Item can be shipped within US but NY.


With a tough stainless blade and grippy textured G-10 handle, the Zero Tolerance 350 folding knife is an ideal choice for law enforcement and military applications. The ZT350 is 10 percent smaller than the original ZT300, yet is just as aggressive. S30V stainless is the steel of choice for the ZT350 PlainEdge blade, which includes a non-reflective, low-friction black tungsten DLC (diamond-like carbon) coating. The G-10 handle, meanwhile, includes textured, matte-black scales to ensure a secure grip.

The knife is also outfitted with the patented SpeedSafe ambidextrous assisted opening system. Invented by celebrated knife maker Ken Onion, the SpeedSafe system lets users smoothly and easily deploy the stone-washed, stainless-steel blade with either the left or right hand. This makes it ideal for sporting and work situations in which one-handed opening is easier and safer, such as when hunting, fishing, or working with your hands on the jobsite. You can even easily deploy the blade in combat gloves using the large, ambidextrous thumb stud or blade protrusion.

And the ZT350 is a breeze to carry thanks to the quad mounting system, which allows for tip-up, tip-down, left-handed, or right-handed clip carry. Bundled with a reversible pocket clip and lanyard hole, the knife measures 7-5/8 inches when open and weighs 6.2 ounces. Zero Tolerance gives a portion of the proceeds for the sale of its ZT350 to the Paralyzed Veterans of America Heritage Fund.

I have been so impressed with the Zero Tolerance line of knives, I decided I would buy their latest superstar. The 0350. This knife was designed as a EDC carry variant of its big brother the 0300 line. As many of you know these knives are a direct collaboration with [B]Strider knives [/B]and [B]Ken Onion[/B]. One look at the the 0350 and you can see Striders handy work all through the knife. ZT states the 0350 is 10% smaller than the 0300 line. This number is very deceiving in real world carry. If you never were to handle the 0300 line, you would say the 0350 is a full mid size folder. "Over build" rings true across the 0350 as much as it does the 0300 line so again, the 10% smaller is kind of misleading .Its dimensions lend itself to a much more friendly EDC carry than the 0300 or 0200 line. The 0350 is flatter in design with rough G10 handles. The thick SS liners are just as impressive as the 0300. There is more steel used in the liner lock than most companies use as their frame. The blade pivot screw uses a more conventional torx bolt but once again, it is a huge pivot torx bolt. There is a distinctive sound ZT knives make when opened..[B]"shlack!"[/B] That is the sound of bank volt lock up. Absolutely no movement in any direction. Its very satisfying and reassuring sound. ZT owners know what I am talking about.;) Carrying the 0350 as a Every Day Carry is pure joy. It works well in jeans, tactical pants or even sweat pants. You just forget you have it unlike its bigger brother the 0300 line. Its flat construction rides close and comfortable with out any flopping around. The ZT pocket clip is the same as the 0200 and 0300 line. It is stiff and excellent. The knife carries much lighter than the 6.2oz weight would have you believe. IMO it feels and carries like a 5oz knife.Read more ›

This knife is great. The s30v steel holds an edge beautifully. I carry this knife every day working in the shipping industry (cutting straps/cardboard). The speed safe opening mechanism is awesome. I recommend aquiring a t-6 torx bit if you like to carry your knife tip up. Also have a t-8 handy for blade adjustments. I will definately purchase another Zero Tolerance knife in the future.

I traded for a gently used version of this knife. It was a great folder and I enjoyed carrying it around. Unfortunately, I gifted it to a friend in the military who really liked it, and I have missed this knife ever since.

To aid you in your decision, here are some of my thoughts on the knife. Think of Zero Tolerance as a heavy duty brother to Kershaw knives. If you own a Kershaw and are pleased, you will most likely enjoy this one. The blade is very tall and slightly thick for it's length, but feels indestructable. The liners on this knife are also very thick and seem strong. The texture of the G10 grips is perfect in my opinion. It seems like you have two things usually happen when you buy a knife with a G10 handle. Either the G10 is very tame and slips when wet (Benchmade), or the G10 is overly agressive, tearing up your hands and pants (Cold Steel). While the G10 on this knife will most likely tear up your pockets over time, it's not nearly as bad as some I've handled and it feels great in the hand. It is comparable to the G10 on my Spyderco ParaMilitary 2. I can't comment on the DLC blade finish, as mine was a special edition with a satin blade. However, the S30V steel used to make the blade performed adequate. It will lose it's razor edge rather quickly, but still retains a very usable edge for a long time. It's a little difficult to touch up if you aren't experienced, but you shouldn't need to do that often unless you are shaving with it. In a day I usually break down boxes, open mail, cut plastic straps and rope. None of these tasks ever took more than quick swipe.

One of the coolest features about this knife is also the reason I only gave it 4 stars, the SpeedSafe assisted opening.

I just now opened the box of the ZT-350. This Zero Tolerance knife is one SWEET blade. It's razor "chicks dig scars" kind of sharp right out of the box, and the fit and finish are impeccable. And the icing on the cake is that it's made in the U.S.A.! - Dang....I've carried an Al Mar SERE 2000 for years as my EDC. I hope the poor fellow doesn't take being retired to hard.

After lusting after the ZT 301 I finally decided on something a little cheaper and smaller to complement my current EDC knife, a Cold Steel AK-47, I will offer a few comparisons with that knife.

This knife is so solidly built it is almost ridiculous. The locking mechanism leaves zero doubt that it will hold the blade in place no matter what, the handle is great, the G-10 scales offer excellent grip without being coarse, and the Speed Safe system is an absolute pleasure to use. I have played with opening the blade using the thumb stud and stopped after a couple awkward attempts, the nub on the back of knife is so easy to use I don't see a reason to bother with the thumb studs. If I were right handed the thumb studs might be a little more useful, as one stud is closer to the handle than the other due to the handle layout to allow for the liner lock.

The blade is smooth and sharp, I think it will hold up quite well to everyday use, I've heard good things about the S30V steel. The pocket clip can be moved into 4 different positions, my cheap $4 Torx wrench stripped itself on the screw when I tried to move the clip today, but when I get another I plan on moving the clip to the left handed, blade down arrangement.

This doesn't have a safety of any kind, but the Speed Safe doesn't seem like it could be flipped by accident very easily. Although nothing is out of the range of possibility. I don't want/need a safety so I don't consider this a negative.


Compared to the AK (another great knife, and a little cheaper for anyone not wanting to drop +$100).

- The 350's blade is slightly smaller, and the handle is a LOT smaller.
