### ⭐⭐⭐⭐⭐ Great knife
*by P***N on 23 March 2026*

### ⭐⭐⭐⭐⭐ Good knife
*by M***G on 30 June 2026*

Great thanks

### ⭐⭐⭐⭐⭐ 420 Stainless Steel blade.
*by M***N on 18 November 2025*

This knife is made from 420 stainless steel from my findings. I really like it and it is cheap. I struggle to sharpen stainless steel knifes in all honesty. I have tried many ways. Next I am buying a diamond stone basic machine that clamps the knife in place and runs the diamond stone along the edge at any given angle. I will go for 20 degrees probably. 420 stainless . This below is copied and pasted 420 stainless steel is harder, more wear-resistant, and heat-treatable, making it ideal for knives and tools, while 304 stainless steel offers superior corrosion resistance, weldability, and is non-magnetic, making it suitable for food-grade applications and medical equipment. The main difference is their intended use: 420 prioritizes strength and sharpness, while 304 prioritizes durability in corrosive environments.
