I am building a shed with poles and have found that I need to find the best way to cut the metal sheathing of a deeply ribbed shed. So last week I spent sixty dollars on used Milwaukee shears, fifty seven dollars on Dewalt shears, seventy dollars on Bauer shears and one hundred and four dollars on Ryobi shears. I was a desperate person. Now let me tell you this. NONE OF THIS CAN PASS ONE AND EIGHTH DEPTH RIBS OF THIS METAL SALON VERY EASILY. However, as they say. RYOBI IS THE BEST FOR CUTTING THIS TYPE OF MATERIAL. It's not easy, but it's WAY BETTER than using metal scissors and way better than the other three scissors. I'm glad I got it!
