$35 · Ryobi Oscillating Multitool

2 piece – P246 & P570 - head removes to take other attachments I just bought it used, plus an additional oscillating masonry blade for just one job - to cut grout out between tiles. Not needed any more. Not something you don’t use often, but extremely handy and time-saving when you do need it No battery, etc, but can demonstrate it if you wish. $35 with used masonry / grout blade
