Forged products are different from general products, but most of them can be compared with a measuring instrument. However, if you magnify the EDGE part by 5000 times with a microscope, you can see a clear difference in density that greatly affects sharpness and durability.
After forging Hitachi ATS314, Michiko shears undergo special heat treatment unique to Michiko in a high-performance vacuum furnace. The difference in the quality of steel products is several to several tens of times larger due to heat treatment technology. The invisible quality of products from other companies is already incomparably different at this stage.
