Blazer PT-4000 Pencil Butane Torch

Blazer PT-4000

The Blazer PT-4000 Pencil Torch is relatively small as far as Blazer torches go. It is pencil-shaped and designed for very small jobs that require a precision flame to be applied in a particular contact area. It is small enough to be carried in your pocket and, therefore, very portable and easy to store. Its many features make it the perfect tool for various jobs.

It runs on butane gas however it must be a quality butane gas so as to avoid clogging the nozzle. Customers have found some novel uses for it, such as igniting campfires and cigars, as well as the usual applications for which it is intended, like making and mending jewelry, plumbing and brazing.
