【DIY】A stunning sight! The craftsmanship of Tsubame-Sanjo shines in this "lifetime" hammer
While surfing the net, I was captivated by this hammer, which is as beautiful as a work of art. It not only has an appearance reminiscent of a starry sky but also features outstanding usability as a high-performance tool that showcases the craftsmanship of Tsubame-Sanjo in Niigata Prefecture.
The hammer that allows you to hold the brilliance of stars
Using a hammer often involves hard physical work or tasks, which can be demotivating... At such times, I came across the ion plating hammer "Hoshikage" while surfing the web. True to its name, it features a beautiful color reminiscent of stars that makes it hard to believe it’s a work tool, turning routine tasks into something enjoyable.
A seven-colored brilliance born from space technology
The biggest feature is the beautiful seven-colored shine reminiscent of space. Thanks to the ion plating process developed by NASA for space development, ionized metal is thinly and uniformly deposited. The high adhesion and durability ensure that its beauty lasts long.
There are three types: octagonal, pointed, and box. You can choose according to your needs, from heavy-duty work to nail pulling. Items crafted by artisans from Tsubame-Sanjō in Niigata Prefecture are likely to perform well in DIY, outdoor peg driving, and firewood splitting.
The wooden handle is designed in an "octagonal" shape that allows fingers to naturally grip it, making it easy to hold firmly. With its flat surfaces, it's easy to determine the orientation of the striking face, enabling straight downward strikes at the targeted position. The power of the swing is transmitted efficiently to the hammerhead, allowing for stable strikes with light force.

You can also get the handle personalized with a name, made of white ash.
The handle is made of durable white ash, which provides a comfortable grip that reduces fatigue even during long hours of work. With laser engraving, each piece features different wood grain expressions.
If you purchase a set of three, personalized engraving is also available. It would be great for siblings to have matching ones or as a child's first tool.
