The SkeletonFX (FX7870GE) is a specialized trimmer designed for contour and precision work, developed with absolute attention to detail. You may have experienced that with a conventional trimmer, the housing obstructs your view of the cutting lines. The SkeletonFX features a 360-degree free-standing T-Blade that gives you an unobstructed view of the cutting line, no matter what angle you hold the precision trimmer. Another advantage of the free-standing blade is that the distance from the housing prevents heat buildup, keeping the blade cool. Additionally, the free-standing blade allows for unrestricted 360-degree use with a Zero Gap function—without the need to remove the blade.
