Japanese blade manufacturer KAI Corporation today announced the global launch of THOLL, an innovative five-blade razor featuring a full-metal construction, on the crowdfunding platform Kickstarter.
THOLL introduces a new alternative to today’s shaving market—dominated by disposable plastic cartridge systems—by combining durability, environmental responsibility, and refined design.
The razor body is crafted from durable metal materials, eliminating unnecessary plastic components wherever possible.
Designed for long-term use, THOLL helps significantly reduce waste compared with conventional disposable systems.
The product draws upon more than 100 years of blade-making expertise in Seki City, Japan, a region globally renowned for its cutlery craftsmanship.
The defining feature of THOLL is its patented* magnetic blade attachment system.
-
The blade unit and front cover are secured using magnetic force
-
Precision engineering ensures safe and reliable operation
-
Blade replacement without direct contact
-
High-durability full-metal handle
This system delivers convenience, safety, and a premium user experience.
THOLL features a five-blade system made from high-quality Japanese steel.
Its flexible head naturally follows facial contours, reducing friction while delivering a smooth shave.
The precision blade architecture provides excellent control and comfort.
THOLL is designed not merely as a shaving tool, but as an object that elevates the daily grooming ritual.Its smooth metal curves and minimalist form blend naturally into modern bathroom spaces while expressing a quiet sense of refinement.
Most cartridge razors rely on disposable plastic units, generating significant plastic waste over time.
THOLL addresses this issue through its durable full-metal construction, requiring replacement only of the blade unit.
From “disposable” to “designed to last.”
