Based on my postal scale, here are some weights with a Sony VTC6 installed (includes weight of the battery):

All aluminum FW3A …………………………………………………………………………………………… 100g
My modded Emisar D4 aluminum with illuminated metal button and bezel board ……………………. 115g
FW3T with Aluminum head swapped in from an FW3A …………………………………………………… 116g
All Titanium FW3T ………………………………………………………………………………………………121g
Ti-Cu FW3T …………………………………………………………………………………………………….137g
Copper FW3C ………………………………………………………………………………………………….169g
Ti-Cu Emisar D4 …………………………………………………………………………………………………Approx 170g

My impressions:

  • The Ti-Cu Emisar D4 and FW3C are too heavy for pocket EDC. They bounce around in my pocket and feel uncomfortable.
  • The Ti-Cu FW3T is borderline weight-wise.
  • The All Titanium FW3T feels good in the pocket, but may have heat issues.
  • The titanium FW3T parts with bare aluminum FW3A head looks surprisingly good, is noticeably lighter, and has less heat issues than all Ti.
  • The all aluminum FW3A feels incredibly light, but lacks the durability of titanium.
