A tone arm with a small double knife edge. Uses a double knife edge that is a bearing system with no diameter and resistance.

In the WE-407/23, the processing accuracy has been improved, and the ultra-high accuracy of ± 1/500mm or less has been realized. In addition, the miniaturization of the double knife edge has been succeeded by the latest high-precision processing technology and the hand processing which can be called craftsmanship, and the flexibility of high-compliance lightweight cartridge has been obtained.

The arm pipe uses a highly rigid light alloy pipe with a special treatment to thoroughly suppress the pipe squeal characteristic of metals.

The main weight uses a helicoid type that allows accurate needle pressure application and has a built-in damping mechanism that absorbs external vibration transmitted from the arm bearing.
