Hello, I have a leaf rake (leaf broom) with metal teeth (22 teeth, width 40 cm, handle 1m30), a little old, and entry-level. In a raking movement a little too vigorous, I took some teeth out of their mouthpiece, but without succeeding in putting them back. Does anyone have a technique, trick or skill for putting them back in their mouthpiece (on the handle side), or is it ruined? happy new year
