| Abstract: |
A multistate precipitation removal tool designed to remove light ice, snow, slush and liquid water from delicate surfaces and to polish frost thereon without harming such surfaces. Materials of appropriate hardness and flexibility over a broad range of temperature have been located and incorporated into a scraping/polishing/squeegeeing tool for use, for example, in the small aircraft industry for preparing aircraft for take-off after precipitation has occurred. Critical in the function of the tool is that it does not damage delicate airfoil or windscreen surfaces while being used for its intended purpose.

What is claimed is:
1. A tool for removing ice, snow and slush from delicate surfaces, polishing frost, and squeegeeing water thereon without damage to these surfaces, which tool comprises in combination:
- a. a plurality of substantially parallel blade members, each of said blade members having a substantially constant, chosen flexibility, said blade members varying in flexibility from soft to stiff, each having a leading edge for scraping and a second edge, each being adapted to be held by hand, said leading edge of the softest of said blade members protruding forward of that of the next stiffest blade member lying next to it, said stiffer blade members being recessed in a stepwise manner from soft to stiff; and
- b. means for rigidly and detachably fastening said blade members, said fastening means being spaced apart from said leading edges of said blade members.
