Review on 🔨 YIYITOOLS YY 3 002 Spark-Resistant Hammer by Dusty Oner

We have been using these jackhammers in our assembly department for about a month. They're used to encouraging stainless steel parts to go where they don't want to fit. They've held up just as well as any other brand we've bought in the past (with the exception of Estwings). The grip of these YIYI hammers is better than most that we have used. You still need to be careful not to bump into the corners or edges of the metal as this will cut the rubber. This is typical for all hammers of this type. The dimensions in the description (60 mm, 50 mm and 45 mm) refer to the diameter of the hammer head. The important numbers are the weight: 60mm is 3 pounds; 50mm is 2 pounds; 45mm is 1.5 pounds. All in all, at $25 a set, I would definitely buy them again.
