Key Technologies Explained

Digital Longlife Brushless Motor

The brushless motor eliminates friction-prone carbon brushes, extending motor lifespan and ensuring consistently quiet operation. The digital control maintains 7,200 RPM even under load for smooth cuts without pulling or snagging.

DLC T-Blade Technology

The Diamond-like Carbon coating reduces friction and heat at the blade surface. The T-blade shape provides enhanced visibility for precision work and a wider cutting surface for efficient line-ups and edge work.

ASSASSIN Visual LED Indicator

The word ASSASSIN on the handle doubles as a 10-stage battery display. Letters glow green at full charge and dim one by one as power drains. Below 20% the logo turns orange, below 10% red. During charging, letters fill back up from bottom to top.
