I recently picked up a new silver Gillette Mach 3 for travel and noticed the handle was much heavier than I expected it to be. I've never had one before but it got me wondering if the new Mach 3 handles are still made of the same materials as the original ones in the 90s and 2000s. Have there been any changes to the base model silver and black Mach 3 over the years? I know the blades themselves have changed somewhat but I can't find any information out there on the stock Gillette handle. Anyone who has had experience with the original and new model please let me know your opinions. Thank you!
