besides post 30 I have another caution...
I don't like my dogs to chew on plastic since the chemicals in them that make them... ah... plastic (plasticizers) are a good bet for cancer or other abnormalities.
I give the dog good ol' fashioned wood (can be a vintage unpainted screwdriver if ya want) or rubber chew toys. He loses interest unless they are new (just like a kid), so I put one away for a while until he forgets about it, then it's "new" again.
And yes, your truck guy wants you to be happy - he sells service - so he'll put it in his vise knock off the handle and put a new one on. Or you can do it yourself.
