GF-8010 vs GF-8011
Short answer. Both are CE-certified propane torches (GK 007996 001) with ABS shells and iron nozzles. GF-8010 is slightly longer (320 mm, 427.4 g) with a pistol grip; GF-8011 is 300 mm and 420 g with a loop handle and its own Chinese design patent.
Which to choose
Choose GF-8010 for a classic pistol-grip look and a slightly longer reach. Choose GF-8011 if you want a design that is protected by patent ZL 2023 3 0152720.X, which helps limit copies in your channel.
