The function of the strain relief reasonably has little to do with the plug type. The design of the strain relief has more to do with it. Blame the manufacturer.
A set of mini-screwdrivers are a must in any case. I need mine everytime the radio/shaver/whatever needs repair.
Every project takes a lot longer than expected. Just accept it. I tried to repair my shaver (without the correct spare parts) the other night. This fifteen minute job started somewhere around midnight and was abandoned when the news anchor said "Good morning".
