why use carbon fiber

• Aluminum (6061-T6):
  ~ 167 W/m·K
  
• Carbon Fiber (unidirectional composite):
  ~Across the fiber (matrix direction): ~ 0.5–1 W/m·K

 It is a thermal insulator and helps protect your hand from heat soak. The weight savings is about 40%. It localizes the heat and also dissipates it better as well.
