Review on Senzal Bike Crank Puller Repair Extractor Tool - Pedal Crankset 🔧 and Bottom Bracket Removal Kit - Bike Repair Tool for efficient Bicycle Maintenance by Marcus Freeman

You must use two tools to remove the crank or you will cut a hole. My first grip. I screwed it onto the crank by hand then used a piece of wood on the other pedal to hold it in place and used the bushing gently to push the crank out and it ripped the threads right off the crank ! You have to use one wrench to hold the tool and the other to turn the outside and then everything will be fine. After removing the first handle, I was able to remove the other three with no problem. I still think the carving is pretty weak. I think it should be tighter.
