I have had that happen with both Gilmore, and Spear & Jackson loppers. Got free replacement blades or anvils in the mail.I called Fiskars . . . sending me a new blade... for free.
My preference is for compound action, anvil loppers for removals. I get a lot of leverage, and good cutting on both green and dead wood. I guess that bypass loppers are better for pruning live, green trees and shrubs that you want to keep.
e.g. : Ace® Compound Action Anvil Lopper, Item no: 7094428 $29.99
