Iwasaki Kamisori

Since 1954, Iwasaki Kamisori has been crafting traditional Japanese straight razors in Sanjo, Niigata—a region renowned for its exceptional bladesmithing heritage. Founded by descendants of Dr. Iwasaki Kousuke, a celebrated metallurgist, the workshop represents three generations of dedication to preserving authentic kamisori forging techniques. Under the guidance of legendary blacksmith Shigeyoshi Iwasaki (born 1933), the brand has become synonymous with uncompromising quality in traditional Japanese barbering tools.

Iwasaki specializes exclusively in hand-forged straight razors, employing time-honored methods that set the standard for the entire industry. Each blade is meticulously crafted using Swedish high-carbon steel (hagane) laminated with soft iron, creating a distinctive asymmetrical grind with a tamahagane steel cutting edge. This traditional construction method produces razors with exceptional edge retention and the ability to achieve remarkably keen sharpness—qualities that professional barbers and wet shaving enthusiasts prize above all else.

The brand's reputation within the bladesmithing community is unparalleled. Iwasaki is widely regarded as the benchmark for Japanese razors, with many smiths in the Sanjo region having trained under Iwasaki-san himself. This influence has helped preserve traditional forging techniques that might otherwise have been lost to modernization. The workshop's commitment to authenticity means each razor receives individual attention throughout the forging process, from initial lamination to final honing.

For those seeking an authentic Japanese shaving experience, Iwasaki Kamisori represents the gold standard in traditional barber razors. These tools aren't mass-produced items but rather functional works of art that embody decades of metallurgical expertise and cultural heritage. Whether used by professional barbers or dedicated collectors, Iwasaki razors deliver the precise, smooth cutting performance that has defined Japanese bladecraft for generations.
