Cutting the Tube Tip
Here's where these newer caulk guns get very convenient. Instead of looking around for a pair of scissors, knife or razor blade to open the tube of caulk, you now have a built-in cutter.
Just insert the tip of the caulk tube and squeeze the handle. As you squeeze the handle a knife edge cleanly cuts the plastic caulk tube tip for you. No extra tools to look for or carry along.
