Option 1 might not be very long lasting as I dont think super glue can hold strong at such small plastic blade

ok dont use super glue..it not strong enough.....use 3 ton glue..."gam bancuh" usually got 2 part....need to mix the glue then paste on it....the glue will dry within 10-15 minute.....the colder will help the glue to dry...try this..it will help..this glue type is last long
