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!

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.
THRUST BALL BEARING
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.
