Brass blades won’t scratch your bronze prop no matter how hard you scrape. Flexible handle allows best scraping angle and the thin blade pops the Barnacles off on the first pass. I have used these for a year now and they do the job. Order a pack of 6 for less than $3 each.
Diver just quit showing up. His phone has full messages. Never heard from him since. Found these scrapers when I was looking for brass so I wouldn’t scratch my bronze propeller. These filled the bill. And work really well not damaging the bottom paint around Thru Hulls. [emoji106]
