The Overwhelming Durability Achieved by Forging Technologies

Since its founding in 1963, KOBAYASHI TOOL MFG.Co., Ltd. has been good at manufacturing tools and blades via “Precision Hot Forging”. Our craftsmen who have no compromises manufacture blades by forging and our blades are now active in the hands of engineers around the world for over half a century. A thing that support us today 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 our own technology. Unlike products from other manufacturing methods, please expect our products that have excellent durability due to our unique forging process.

Performance Test Results

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

(a) Forged blade (our product)

White brighter part along the edge after the test shows the black surface finishing (corrosion resistance) being grinded off.
The edge is not lost at all after the test. Sharpness of blade is maintained almost same as that before test.
The hairline pattern on the blade surface is scratch mark given by copper wire during the cutting test.

(b) Lost wax molded cutter (Taiwan product)

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.

When the test reached to 400 times cutting, this cutter was broken (spring on handles is broken). The test was discontinued and this photo shows the blade condition at this time. 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.
