Sensei Open Neutral Grip 40 Tooth Hair Thinning Shear

Sensei Open Neutral Grip 40 Tooth Professional Hair Thinning Shear takes the concept of an offset thumb and extends it forward to where your thumb naturally sits at rest. There is not cramping and this concept removes pressure from the palm of the hand, and reduces muscle fatigue. The neutral thumb position removes 75% of the distance required to open and close the shear, and is built to maximize your efficiency, and minimize stress on the hand. This Open SOT-40 Thinner is the first step to a healthier, pain free way of working. Made with high quality Duralite™ Japanese 440C Stainless Steel. The finger rest on the Open SOT-40 Thinner is removable, and adjustable with the option of a traditional tang as well as the lower full Neutral Position.

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.
