The Overwhelming Durability Achieved by Forging Technologies

Since its founding in 1963, KOBAYASHI TOOL MFG has been good at manufacturing tools and blades via “Precision Hot Forging”. Our craftsmen have made no compromises in our production method that uses forging to produce cutting tools for over half a century. KOBAYASHI TOOL MFG products are now active in the hands of engineers around the world.
What we focus on today is the technology of “precision hot forging” which can not be imitated by other companies.
It is almost impossible for other companies to manufacture thin blades using a forging process. We realized this by utilizing KOBAYASHI TOOL MFG specific technology. Unlike products from other manufacturing methods, please expect excellent durability due to the use of a unique forging process.

Performance Test Results

The microphotographs (50x magnification) below show the comparison of the endurance test result ( 500 times cutting test of 325 sq.-mm copper wires) among;
(a) A Forged cutter (KOBAYASHI TOOL MFG product),
(b) Lost wax molded cutter (Product of Taiwan)
(c) Blanking machined cutter (made from plate material) (Product of China)

(a) Forged blade (KOBAYASHI TOOL MFG product)

The brighter white area along the edge of the blade after the test reveals that the original black surface finish (corrosion resistance) has been ground off.

The structure of the edge is completely maintained despite the strain of the cutting test. The sharpness of the blade is mostly maintained and is almost as sharp as it was before the test.

(b) Lost wax molded cutter (Product of Taiwan)

The edge (grinded part) is completely lost and broken.

It is afraid that the service life might come to the end before long if continuing usage.

The many ditches on the blade surface are scratch marks given by copper wire during the cutting test.

(c) Blanking Machined Cutter (Made from Plate Material) (Product of China)

By the 400th cut, this cutter had broken (that is, the handle springs had broken down). At this point, the test was discontinued. The photo shows the condition of the blade at this time. The edge (grinded area) is completely destroyed and broken. The possibility that the service life of this product might soon come to an end with continued use is reason for concern. The many deep scratches on the blade surface are marks created by the copper wire during the cutting test.

The quality of blades made by forging are incomparable to those made by casting methods (Lost-wax). From the beginning of blade production, reports of blade damage are non existent. Moreover, all operations are carefully inspected after their completion. We pursue compactness and maintainability by utilizing the design technology of experienced development staff.
With a strict management system, we aim to pursue higher quality product creation. Currently promoting research and development of patented products day and night, KOBAYASHI TOOL MFG products are now widely exported not only to Japan, but also to the United States, Europe and other Asian countries.
Since functional parts can be continuously repaired, they can be used for long periods of time. KOBAYASHI TOOL MFG maintains the production of high quality, reliable technology for long term use.
