Great knife
Great knife from ZT, a slip joint folder and a good slicer for opening envelopes, cutting small items and a fantastic collectible.

ZT0230
My addiction to knives aside, this looked like a good candidate to carry in my pocket at times a clipped knife is better left at home. And it fills that role very well - slim, light, sturdy and short. This is a beautifully built and finished knife by ZT (my fourth), and is easy on the eyes with the black CF, blue backspacer, and nicely ground SW blade. The scales are subtly contoured and feel great in hand - exactly long enough for four fingers in my med/lg hands. The 20CV blade came paper-slicing sharp and if it performs like my 0393 the edge should retain very well. Now for my only complaint - this knife has premium materials and modern design, but $180 is a lot of money for a small slipjoint. But if you can handle the price it's a wonderful knife.

Great knife
This Anso slipjoint knife is a great design and fun small nick knife. Great for opening envelopes, packages. Or as a ZT collectible.

Great knife
Great little pocket knife. Good for opening boxes and envelopes. Great design for collecting as a ZT knife. I respect each knife designer and try to add each design to my collection

True knife
This slipping folder was primarily purchased for my personal knife collection. A "closet queen" as you may say, however it came super sharp and a great little Zero Tolerence knife.

Nice gentlemans knife, but not for active duty...
This is a very well made knife. The blade is perfect and the handle fits well in the hand. The only issue is that the detent system is not designed for EDC. Conventional slip joints generally have a fairly stout homing of the blade in the open position. But this modern detent system does not have the feedback of the traditional designs.
