The purpose of this article is to show you how to modify your Motobilt Bottle Opener Gusset to make it functional. We do not make this modification before shipping due to not knowing which side you will need to file down. This can be done with a hand file, die grinder, or Dremel Tool. As you can see in these pictures only one side of the tab in the gusset is modified to open a bottle top. If you have any questions be sure to comment below or CONTACT Motobilt for more details.
