The heated blade slices through most grades of sleeving and seals the ends to prevent fraying during installation. We offer an assortment of tools to accomplish this, ranging from heavy duty, high volume devices to portable gas powered units. German engineered, Heavy Duty Handheld 220 Volt Hot Knife.
