Pro Hammer (top right) and Pro Hammer Mini (bottom left), powerful professional hammers that won't lose to pegs.

A masterpiece Made in Tsubamesanjo: The industry's first 0.3mm titanium double tumbler (according to our research).

Ultra-lightweight 40g: All-titanium single mugs in 2 types x 4 colors.

High durability & powerful striking: The world's first 2-Way peg hammer (according to our research).
The Pro Hammer pursues resistance to deformation, durability, and powerful striking. It joins 'tool alloy steel (HRC48-54) for the cylindrical part requiring strength' and 'carbon steel (HRC40-50) for the plate part that won't deform upon impact' using a 'cross lap joint' and 'L-shaped welding.' The concept is a stylish, powerful professional hammer that won't lose to pegs.

As a new endeavor, by sharing a handle with the Pro Cut Saw folding saw, it enables a 2-Way function as both a peg hammer and a saw. The exchange process can be done with a coin and by hand, making reconfiguration possible in outdoor settings.

The lineup includes two sizes: the full-sized Pro Hammer capable of driving 500mm pegs, and the compact Pro Hammer Mini capable of driving 300mm pegs, allowing you to choose based on your needs and portability.
