Shingle Eaters are the only brand I'll buy. Me and my crew tried all kinds of tear-off spades from the {Big Box Stores} and either the handles will bend or the teeth will snap. Our favorites are definitely the yellow ones with the red handles-Shingle Eaters. They work the best and they last. We have been roofing on Long Island, NY for the past 16 years and have used various demo tools and ripping bars. By far, thewse yellow shingle eaters give the best durability and strength. Other bars will actually bend or bow, making it impossible to get the nails and adding time and effort to your job.
