CF carbon fiber lever

[Alan Barnard]

Sorry, but something is seriously wacky with your assessment.

 The carbon fiber Fujan feels like almost nothing in your hand. It is extremely light. I own the Jahn extension hammer and it is, as hammers go, very heavy.

I have NO anxieties about the durability of the Fujan. It is designed by an engineer (Mr. Fujan) and manufactured  with exceptional quality.
