The Chinese razor technique is a comprehensive men’s haircut in which the Chinese razor (feather razor) ceases to be merely a tool for customization and becomes the primary instrument for shaping the entire style. The course demonstrates how to transform simple, flat, and lifeless hair into a modern, textured mullet-style haircut, based on the deliberate use of irregularity and movement.

Marek Krzyminski guides you through the entire process step by step: from a precise sectioning system based on the anatomy of the head (midline, mastoid process), through building an elongated back using the 90-degree layering technique, to creating volume on the sides with high-grade layering. The course demonstrates how to strategically introduce a disconnect between the sides and the back to achieve the longer hair behind the ear characteristic of a mullet, while maintaining the cohesion of the overall shape.

In this course, you'll learn:

  • A complete haircut from start to finish using only a Chinese razor—no clippers or scissors
  • Strategically creating a disconnection behind the ear as the key to creating a modern mullet
  • A 90-degree flap technique with controlled extension below the occipital bone
  • Creating volume on the sides using layering – when to comb from the top and when to comb from the bottom so that the hair accumulates over the curve of the head
  • Cut the bangs with zero tension to prevent them from "popping back" after drying
  • The technique of "scraping" with a knife along the top in a triangular shape to lighten the crown while maintaining the weight of the fringe
  • Style your hair with a sea salt diffuser to bring out its natural texture and movement

After completing this course, you’ll start using the Chinese knife as a full-fledged creative tool, not just for finishing touches. You’ll understand the philosophy behind working with this tool—where balance and proportion are more important than a perfect line—and you’ll learn to consciously create dynamic, fluid shapes that will bring your clients’ straight, flat hair to life.

Frequently Asked Questions

What tools do I need to cut this hairstyle?
The main and only cutting tool is a feather razor. The stylist uses it to create the entire shape, deliberately avoiding scissors and clippers. A trimmer may be needed only for any necessary, gentle touch-ups to the outline.
What type of hair is this technique best suited for?
This technique is ideal for straight, flat hair that lacks natural movement. Using a Chinese razor revitalizes this type of hair, adding texture, movement, and lightness that cannot be achieved with classic scissors.
Is precision and a clean cut the key to this technique?
No, quite the opposite. The instructor emphasizes that working with a Chinese razor is all about creating controlled irregularity. The goal isn’t the precision associated with scissors, but rather achieving balance, movement, and plenty of texture in the hairstyle.
Is this course suitable for people who have never used a Chinese knife before?
Yes. The course is designed for hairdressers who want to learn how to use a Chinese razor as their primary tool for shaping hair. The instructor explains the technique in detail, so no prior experience with a razor is required.
Does the course explain the system for dividing the material into sections?
Yes, the instructor explains the entire sectioning system in detail, using anatomical landmarks such as the midline and the nipple as reference points. They explain why specific sections are created and how this affects the final shape of the hairstyle.
Does the course also show how to style this hairstyle?
Yes, the final section of the course is entirely devoted to styling. You’ll learn which products to use and how to work with a diffuser to highlight the natural texture and movement created by the razor cut.
How long is the entire video?
The video tutorial is 79 minutes long and shows the entire haircutting process step by step, from sectioning the hair to cutting it and finishing the style.
