I've got one of those also, great for trimming fiberglass out of a mold or on the boat. Check out this ebay seller for blades specialtydiamondcaseboy said:for removing old sealant, i have one of those multi tools from harbor freight. i finally got the chance to use it. the scraper took off the old vent sealant like it wasn't even there, going right between roof panel and vent edge,and the cutting blades were amazing for cutting out rotted struts and such. by far one of the coolest tools ever.
