Our knives are built to last. Cleaning and caring for your knife will maintain performance and enhance the life of your knife.

Tips for Caring Folding Knives
  • Keep your knife dry; that means the entire knife, not just the blade.
  • Keep your knife clean, particularly moving parts and locking devices.
  • Keep your knife oiled; especially pivot points and the blade. Oil at least twice a year.
  • Keep your knife sharp; a sharp blade is safer than a dull one.
  • Again, store your knife in a dry place.
Tips for Caring Kitchen Knives
  • Always use an appropriate cutting board in the kitchen to get the most out of the sharpness of your knives.
  • Cleaning knives after each use will keep them in the best condition and promote food safety.
  • Knives require a safe dry storage place, and a knife block is perfect for storing knives.

What a beautiful surprise

I didn’t know what to think. The review of it on U tube didn’t do it justice. This is in the top level on of high end knifes costing 3 times as much. It looks perfect the fit and finish it excellent The action is as good as my high end knifes. I love the feel in my hand and the blade is the best coated blade I have seen. Hardness is 64 Rockwell and it is wicked sharp. I will definitely be getting more KATSU knifes. I won’t have to think about it.


This is a great knife. Well crafted and well made. The materials are top notch.

A work of art for an affordable price

This has all the fit and feel of a custom knife but for 200 dollars less than most customs at their base price. Don't let the front flipper action sway you either as once you get used to it, which doesnt take long by the way, it feels like an absolute dream. And as for the edge? Like a laser right out of the box! Absolutely phenomenal knife that I havent been able to keep out of my pocket.

Is it an art or a knife. The KZ-S1 by Katsu

Sorry about the title but in my humble opinion this knife is sheer perfection. I would go so far as to say that it looks like a Custom Knife at a bargain price wise especially when you consider the materials used and the fit and finish.
It not only looks good but razor sharp out of the box. I’m so happy that I took the plunge because I thought it might be a scam, I mean when you consider all of the premium materials used and each knife is hand crafted polished and sharpened. Honestly I think I got a bargain, a semi custom knife at a bargain basement price.
I will definitely be buying from Katsu again. BTW the customer service is excellent, something I value very much.
