Mizutani Scissors - BLACK-SMITH Solid LEFTY


The BLACK-SMITH Solid LEFTY are the result of an analysis done by two professors who specialized in Ergonomics and Metal Engineering, respectively. The center of gravity in this model has been shifted closer to the hand to prevent wobbling during cutting, while a unique hardening process based on thorough temperature management brings out the special characteristics of the materials making this a perfect all-around scissor. For barbering, we recommend 6.5 and 7.0.

A collaboration of these wild guys and professors!

The new Ph.D. collaboration monster SOLID is amazing!

1.Well-balanced scissors with our G-SHIFT wobble prevention functionalityfor comfortable handling

When using scissors that can’t fix the handle in place and don’t have good balance, it takes extra effort to prevent wobbling. For stylists who open and close their scissors hundreds of times in a single day, even the slightest extra work can cause finger and joint pains. With the innovative new “G-SHIFT” design, the scissors’ center of gravity is shifted closer to the hand, while keeping the balance set and avoiding increased centrifugal force during opening and closing operations. Together with the new handle that molds perfectly to your hand, these elements stabilize the blades, and prevent wobbling during cutting.

We investigated muscle activity in the hand at the Chiba Institute of Technology.

2.Thrust Bearing design for ultra smooth operation that won’t tire you out

The joint section has the important role of joining the blade and the handle, and in these scissors, it’s fitted with 9 precision ball bearings. Thanks to this design, the movement is smooth as silk.


3.Powerful and long-lasting: Extramarise® Processing

The new solid uses our proprietary Extramarise® Processing, a unique hardening process based on thorough temperature management that brings out the characteristics of the materials to the greatest extent possible. This process gives the scissors the hardness they need, as well as sufficient durability. This time, with the cooperation of the metals engineering expert Dr. Asakura, we’ve analyzed the structure of the SOLID’s raw material following the proper heat treatment processing. Comparing the SOLID’s treated material with other untreated materials, the difference is obvious. The results of this analysis proved that heat treatments can make a huge difference in scissors’ working life.

We investigated the structure of the SOLID 
at The University of Tokyo.

EXTRAMARISE® is a proprietary heat treatment ideally suited for haircutting scissors that was developed by MIZUTANI based on long years of accumulated data and experience. The same steel material can have totally different performance depending on the heat treatment used. Therefore, to maximize the special qualities of the rare metals (cobalt, molybdenum, vanadium, etc.) we’ve added to our products to the greatest extent possible, and achieve the ideal metal for scissors, (*hardening, tempering, sub-zero processing) and other complete temperature management procedures are essential. To bring out the distinct characteristics of materials, and manufacture a blade with the ultimate strength required for haircutting scissors, we at MIZUTANI have implemented our own proprietary heat treatment using the ideal temperature for scissors: EXTRAMARISE® processing.
These are small, precision metal ball bearings with excellent axial load-bearing ability. Due to their design, which enables radial load-bearing as well, scissors open and close smoothly, which both lessens burden on the hands and contributes to a long cutting life. With anti-rust properties and durability as a matter of course, these bearings are a Japanese-made product.
The handles are so designed that they look nonmetallic, alive and organic. You may feel some warmth from the three-dimensional, twisted handles, and once touched, you would not like to part them from your hand.
Compact and easy to turn, this is a flat type driver for UFO screws. This screwdriver is included with all scissors with the mark shown.
