Treeline is proud to offer the Razertip line of woodburners and woodburning pens. These tools have been setting the standard in Canada for 30 years and they are now available in the U.S.. The power and recovery is the same for both the Razertip Single Burner and Razertip Dual Burner but the Dual Burner allows you to have two pens plugged in for immediate use. Both woodburning models feature near instant heat response, small and lightweight wood burning handpieces and an excellent warranty (3 years on power supply and 1 year on handpieces).
