What is the difference between the Jetstik and a Rosebud or an Acetylene torch?
TOP A: The Jetstik is an internally combusted flame as opposed to an externally combusted flame, giving a lot more velocity and rapid transfer of heat than other common torches. Also, a Rosebud or Acetylene may get too hot for the stone causing more frequent fractures. The Jetstik allows for better control and consistency.
