I can relate to not wanting to throw something away if you can just fix it, but I guarantee you will save yourself a lot of time and stress if you just go down to your local thrift shop with a kitchen section and pick one of the dozens of spatulas they will have for like $0.50.
The last thing you want is the mess and possible pain of your repaired spatula breaking under the stress of lifting a hot, oily food from the pan.
Ours is like this and is at least 12 years old. I believe the plastic is over molded directly onto metal handle which sits about 1.5 cm into the plastic.
It got slightly melted along the leading edge once, so I trimmed/files it back to make it chamfered again.
I’m sure it sheds some microplastics, like pretty much everything, but I prefer a little of the spatula, to scraping the nonstick ceramics.
We really only use this with a couple pans, and use metal in our cast iron, though one of our favorite metal spatulas has a plastic handle that’s been melted dozens of times from resting on the rim of the pan.
