Fiberglass also starts to break down in sunlight. I have a couple items with fiberglass handles, but they stay in the shed when not in use. Fiberglass in your hands sucks.
I used the same fiberglass handled hoes, shovels and roofing tear-off tools for almost 10 yrs every day on roofs in the sun. Mine held up fine. Daily abuse, sun exposure.
Fiberglass in your hands are just something that comes with the job. Good thick callous hands take care of that.
Lest you got girlie- hands
