Mayhew "Tools 10655 Brass Scraper, 3/8-10mm x 5-1/2""", multi

I use this to chip corrosion, rust, riverbed muck and crust (nice) off of metal objects I dredge up whilst magnet fishing so's I don't scratch the treasures. It works great, no moving parts. The best brass shaped stick I have ever purchased...

I actually purchased this to clean the grooves of my golf clubs. Because it is brass, it is softer than the face of the club and will scrape out the gunk without carving away metal and changing the groove shape. Perfect “off-label” use.

This is a brand new gasket scraper and in the bag it's all beat up, not a clean edge, dented, not square. Can't use it directly out the bag.

I use this is my EDC pry bar. It is just the right size to work well -- not too big but still a useful tool. The brass does not mar steel, so it is good for weapons and other steel tools.

This brass tool has been a game changer to clean the compensator on my Staccato XC. This thing destroys carbon buildup and the brass is less likely to damage the steel/finish on the XC. I've used it on several other platforms with great success also.
