Most people don't know the difference between these and Philips and neither did I until I watched your videos. These fit like a glove! Way less likely to strip.
Also quality is great.
I have been turning wrenches for a long time. I decided to pick up this set of JIS screw drivers and I have to say, these work excellently! I am very happy with my purchase. Supporting guys like Mr. Niemela is the icing on the cake.
I got this after stripping a kill switch screw, which is not a fun screw to try and get out if its rounded. Everything I get from Pryme is top of the line quality wise, so you can expect these to be no different. Definitely keeping these separate from the old Harbor Freight set so I'm not tempted to use them to open boxes or pry things with, I wanna keep them fresh!
I opened the package and literally used these on some stripped screws on my bench grinder 2 seconds later. The standard Craftsman screw drivers just weren't cutting it but these were able to salvage the screws. 10/10. Stop stripping screws!
