The OEM Bosh gas stove top knobs failed and we needed to replace them.
Small grinder and pliers.
Repair & Advice
The new knobs which were delivered timely and had an added feature to prevent their premature fracture, a metal insert that reinforced the knob plastic (great idea). Unfortunately the ID was too small and required too much force to install them on the gas valve stem. I used a Dremel grinder to slightly trim the valve stem; and a pair of pliers to slightly pinch the valve stem, after which they fit fine.
