Hard Use
This knife is exactly what we all expect from ZT.Not a surprise to get an overbuilt hard use knife.Knife came sharp and centered as always from ZTOnly con is the pocket clip,but I will admit it’s better than most other ZT models.

ZT 0203 DuraLock
Personally, I like Zero Tolerance knives due to their rugged, sturdy build, and the unmistakable tactile sensation of having a substantial tool in my hand. Premium steals, excellent craftsmanship and durability are a ZT given. There are other brands and smaller Zero Tolerance knives that are well-made, and well-crafted; I’m just partial to the industrial-strength variety. They remind the holder of the steroid-using weightlifter who has spent years in the gym. I like the large bolt at the joint and the metallic thud when it snaps out of the frame into a locked position. I have a number of Zero Tolerance knives, and have just added the ZT 0203 DuraLock. It is now my favorite. It’s lighter and more pocket-friendly than the 0308, yet as tactical and rugged.There is an odd thing about knives. Every knife has some outstanding features, but in the end, there is a certain unique feel, a visual and tactile experience to the knife you like that is very personal, and that feeling surpasses the physical qualities of the knife. Like relationships, it’s a combination of quality, how it looks and how it feels. For me, the ZT 0203 has this quality.

Return to form for ZT
After owning the 0203 for over a month this flipper has become one of my favorites for EDC, and outdoor adventures. Love the crossbar lock! Silent to open with the thumb studs, quick and easy to close with the lock slider. The beefy 4" M4 blade is very sharp out of the box. Feels very nice and secure in the hand. Longtime fans of ZTs over built aesthetic will feel right at home with this one. A little on the heavier side, but if you can't handle 6 ounces in the pocket, look elsewhere. And of course this bad boy is made in the USA!
