Product detailed description
Electrician's Knife DENKO Warikomi KT-407 Traditional Japanese Folder
The DENKO KT-407 model is a traditional Japanese slip joint electrician's knife, whose design has remained virtually unchanged for over 100 years. To this day, it is used for electrical installation work in Japan and is also gaining popularity among outdoor enthusiasts due to its authentic retro style. The blade has a drop point shape and is decorated with a delicate bamboo engraving that highlights the knife's Japanese character. The blade construction is of the WARIKOMI (clad blade) type – a hard SK-4 carbon steel core is clad with softer layers, ensuring a combination of high sharpness, durability, and easier maintenance. The laminated wood (plywood) handle, complemented by a classic brass bolster, provides a firm grip while giving the knife a traditional look. The knife is robust, reliable, and ideal for more demanding work where you can utilize its solid construction and higher weight. This tool is manufactured directly in the workshops of Kanetsune - Kitasho Co., Ltd. in the city of Seki, Japan, which is world-renowned for its steel processing tradition.

Japanese precision and traditional materials
Kanetsune production is defined by the use of premium Japanese steels and natural materials that give each knife its unique character and spirit. The key pillars of the brand include:
- Traditional carbon steels: Kanetsune expertly works with steels such as Blue Steel (Aogami) and White Steel (Shirogami), known for their extreme sharpness and ease of sharpening.
- Damascus layering technique: Many models feature multi-layer construction, enhancing blade durability while creating stunning visual patterns.
- Natural handle materials: Traditional woods such as magnolia or oak, as well as ray skin-wrapped handles, provide an authentic feel and excellent ergonomics.

The Kanetsune Seki portfolio bridges two worlds. On one side, it offers high-end kitchen knives that deliver exceptional precision in food preparation.

These knives are built to withstand demanding conditions while maintaining outstanding aesthetic value.
