What are the differences between the Ichi-Nino-San series vs the Cronos series?

Here is the reply by Martin, our Canadian Mizutani scissors fitter:

Hi Chang,

Thank you for your continuing support with Mizutani Scissors Canada.
In terms of both the Ichi-Nino-San series and Cronos series, they both uses cobalt alloy forged through a proprietary heating process called Extramarise. In terms of cobalt density of the alloy, they are very similar.

However...

Ichi-Nino-San Series

Materials Maximized

EXTRAMARISE I

EXTRAMARISE® is a proprietary heat treatment developed by MIZUTANI based on long years of accumulated data and experience.
This process brings out the special qualities and distinct characteristics of the rare metals such as: cobalt, molybdenum, vanadium, etc.
The goal is to maximize the materials, and manufacture the ultimate strength required for haircutting scissors

Designed For Efficiency, Effectiveness and Excellence

Let the scissors do the work for you.

Ichi-Nino-San 1
Designed for detailing work and shows it's true strength in cutting hair-lines and point cutting techniques.

Ichi-Nino-San 2
Designed with R-shaped blade that can smoothly cut while releasing the hair. It can smoothly glide through dry hair without damaging the hair.

Ichi-Nino-San 3
Designed for volume control and for creating direct texture upon contact. It has a 15~25% hair cutting ratio and leaves no demarcation lines.

Ichi-Nino-San 4
Designed for volume control and direct texture upon contact. It has a 15~25% hair cutting ratio and leaves a natural soft and airy  blend.

 

Cronos Series

A New Cutting Philosophy

Developed in collaboration with Mr. Kazuya Kubo of BAGZY from Japan
The Cronos series was developed to improve the haircut speed by simplifying the user's cutting techniques - an important facet for both novice or experienced barbers and stylists alike when training.

"It is surprisingly difficult to adjust hair texture with the all-round 25% thinning scissors that many barbers/hairstylists use. If the stylist is inexperienced, the ends of the hair strands will be too thin, but the roots will stay thick. When the hair grows back, it often loses its style.

I thought up a system of using three types of thinning scissors:

50%
9%
3%

By using each of these thinning scissors the right way, we can target and tackle each hair types' needs. We created an educational tool that gives motivation to professionals and students."

Cronos 1 An all-round cutting scissor. Designed for detail work and point-cutting techniques.

Cronos 2 These scissors are designed with an R-shaped blade that can smoothly cuts while releasing the hair. It can smoothly glide through dry hair without damaging the hair.

Cronos 3 50% cutting ratio. These scissors are designed for speed cutting by volume control while creating a soft perimeter cutting-line at the same time.

Cronos 4 9% cutting ratio. These scissors are designed for directing textures into hair. Ideally used for adding movement and softness to hair flow without leaving cutting line behind.

Cronos 5 3% Cutting Ratio. These scissors are designed for safely adding textures starting from the root. Ideally used for detail barbering work and pixie cuts. It has a slimmer tip of blade for detail work.
