Narrow Blade Concave Cutters by Roshi Bonsai Tools 7.25"

I have used these 3 times since i received them 2 weeks go. They have already bent and dont conpletely close anymore. They look nice but are not the strongest concave cutters. The rest of my order work perfectly, the only issue i had was with these. They no longer close enough to cut.

Super fast shipping. Came with protection for blade .

The blades don't match up. They're useless.
