The Fucking Adapter is a high quality, affordable fucking tool. It is electro polished for a super smooth surface. It fits any vac u lock dildos, so you are not tied down to one particular cock. It can be used in the anus or vagina. The Fucking Adapter works on most Sawzalls or that type of reciprocating saw. It adapts the saw to the dildo in just seconds. Some saws you will need to remove the guard to attach. Note The new style Ryobi reciprocating saws with the quick release will not work with The Fucking Adapter. The old style is fine, it uses an allen screw to tighten the blade. The adapter is 5.5 inches long and 1 inch wide.
