Sensei Revo Rotating Thumb Professional Hair Cutting Shear

Sensei Revo2 Rotating Thumb Professional Hair Cutting Shear is a state of the art cutting tool. Designed with the finest Japanese Cobalt Molybdenum Alloy Steel. Sensei is one of the few companies to cryogenically temper this grade of steel. Tension is controlled by a Ball Bearing leaf spring system to reduce friction, and will feel like new for many years. A Polymer Glide has been inserted into the Pivot Area of the shear ( where the shear opens ) to eliminate metal to metal wear, and keep the shear operating smoothly. Handle is a version of the original Hineta Crane design. The Rotating Thumb turns effortlessly on a sealed bearing to insure years of problem free performance. An Excellent Rotating Thumb Shear.

FAQ's

Which shears are best for me?

Which steel sheer quality is better, those made in Japan, Korea, or Germany?

Japan has the highest standards for workmanship and quality with steels in hair cutting shears.

Many shears made in Korea which can save some costs on labor, and still maintain good quality.

Use steels from Japan. Look for Japanese Steel.

What metals are used in my scissor?

YIron, Carbon, Nickel, and various other alloys like cobalt, and manganese. When using stainless Steel Chromium is added to make steel Stainless, and prevent rust. Handles are welding to the blades and not constructed using the same quality steels. This is not necessary and would add to the cost.

What are the different categories of stainless steel used to produce hair cutting scissors?

Steels are important to a point in a scissor, and when combined with high-quality machining and design you have a beautiful cutting shear ready to provide excellent performance for many years or career depending on the quality of service the shear receives.

You should never purchase a scissor with a stainless steel rating of less than 440C. This is an industry-standard for stainless steel in hair cutting shears. There are a few entry-level shears made using 410, and 420.

Cobalt Alloy Steel is abrasion resistant and will give increased blade retention, and a longer last edge. These shears can also be machined to a finer edge and have the steel hold the edge the result of adding Cobalt Alloy.

They often cost more due to the increased labor costs of finishing and polishing and extra abrasives used in the finishing process.

Cobalt does have some categories and some companies use there own. They include Cobalt Alloy, ATS-314, V-1, V-10 and now they are using a powered Sintered Cobalt Alloy that is expensive but has excellent performance, and with the use of the sintered powered steel process has great quality control when producing it.

Is there a scissor that never needs to be sharpened?

This is fiction, and simply not true. There are high-quality steels that can hold an edge longer than others with the use of Cobalt Alloys but the longest we can see a shear used everyday cutting hair to last is about 18-24 months and most need to be serviced in about 12 months.

This depends some on the use of the shear how many cuts per day.

The wear resistance when cutting strands of hair is the same as cutting equal diameter strands of copper..! Hair is Keratinized Protein, soft and pliable with strong resistance to cutting.
