This is the ultimate extractor combo and uses the very first crop-cut  blade design that utilizes  our Hydra Edge Technology. Gasket pro tools introduced the HCC-1 in late 2017 as a 93 durometer squeegee blade.  This combination is designed to give maxim flex without sacrificing the ability to the best extraction comb available.
The Yellow blade is our  “Sledgehammer”which is rated at 93 Durometer. This is a relatively hard squeegee in comparison to others but the design  allows it to contour to the glass a little easier than the full size  Sledgehammer blade all while retaining the firmness and durability.
 
The choice is clear  you can hammer  your way to extraction action.
