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".

And there are lots of Schuko plugs with terrible strain reliefs. I had one with a plastic strain relief that broke into pieces when I tightened the screw. And one from an extension cord always lets the cord slip out. I once had a swiss plug that had a real nice metal strain relief though.

The Schuko CEE 7/7 (combination French and German) plugs I've bought in the past are ABL brand.
Plastic strain relief, but if you are careful and tighten the screws evenly, it doesn't crack and grips the flex jacket very tightly.
The Swiss plug I'm whining about has a plastic strain relief and the cavity is slightly larger than the flex I was using (SJT 18AWG x 3 cord) so while it does grip it, it doesn't grip it tight ENOUGH like I want. The working space is also kind of cramped.
Who remembers those cheap-ass British plugs that used to have a thick CARDBOARD cable clamp?? I'm not kidding!!
I have a couple of these - they've very old -from back when UK plugs didn't have sheathed pins.

Quite a few of the old British 2A and 5A plugs had quite fiddly screws as well.
As for the cord grips, they were some sort of fiber strap, but of variable quality. The real el-cheapo versions were thin and often disintegrated if a plug had been used several times, or if someone was a bit heavy-handed tightening down the screws.
Even quality makes such as MK used these fiber cord grips, although theirs tended to be much stronger. Here's the arrangement (this one is an old MK BS1363 plug):

The Schuko combination plugs you got are heavy duty type, they're naturally better than most other stuff. Maybe they're even outdoor rated. I've seen metal strain reliefs, fiber ones (not that bad, I never had one break), good plastic ones and bad plastic ones. The one I'm talking about was a plain thin strap of plastic. When I started tightening the 2 screws (2 turns on each screw, then change again) it first started to bend, then it suddenly cracked. All the other ones I've seen grip cables down to 3x 0.75 mm2 perfectly. The only thing that doesn't really work is SPT2 zip cord. Most people wrap lots of electric tape around the cord (did that myself, what the heck can you fit to such a device, Euro and contour plugs are not available and I definitely don't like to get a whole new cord, there used to be crimp-on Euro plugs but they were banned since most people just stuffed the strands into the connectors and didn't crimp them, I've even seen very rare rewireable Euro plugs, but for some reason they're prohibited by the Austrian code). Kopp plugs even have the cord grip flexibly attached to the case, so it can't get lost when the screws are out. Once the screw thread ripped out of the case on such a plug. Can't remember when I last bought a new Schuko plug, I all take them from old appliances etc.

Excellent question. I use them for various home-made adapters on my workbench for fixing up old radios made for use outside NEMA-config countries and plugging them into a step-up 110-220 volt transformer.
I have radios from Germany, the Netherlands and a couple from Australia and Great Britain.
Sure I could always cut off or unscrew the weird plug and replace it with an American-style plug and use an adapter but then that would just add to confusion were I to give the radio to someone else.
And I'm not really happy with the quality of the plug adapters sold here. I prefer to make my own using 7"-10" lengths of three-conductor SVT cable and appropriate male and female connectors. More expensive, but worth it.

Paul, I think that in some respects, those adapters, should be banned. I recently saw an adapter, to convert a Schuko plug to an NZ plug and when the two were fitted together, there was no Earthing on the Metallic frame of the appliance (A German Commercial Pop-corn Maker). Also, I remember a tourist from Canada, a few years ago, brought his wife's Hair- Dryer in to work to be repaired, it was extensively damaged, it was a 120V type, he told me that the guy in the shop in Canada, told him that the adapter would "work" in any country in the world!. Where do these people come from?,eh?.
