Look at SK tools lots of choices of both and you can get good deals on sets.
The western forge made, SK branded diagonal cutters suffer from a lack of edge retention. I like the green grips though.
As for their hard handled screwdrivers, SK screwed the pooch by slapping what appear to be pry bar handles on the screwdriver blades. The handles are too large and cumbersome. They need to copy the older, French made SK handles and bring the taper back.
There are far better options out there to choose from.
What are you working on? If you happen to work on Japanese stuff like throttle bodies and the like, you need to invest in a Vessel P#2 that will fit those pesky Japanese screws perfectly.
You could also get a bit holding screwdriver and buy P2 bits as often as you need to. Nothing lasts forever.
As for Diagonal cutters, you may want to consider a pair of mini bolt cutters if you're cutting more than wire to save your dykes for wire. There are several German brands from Knipex, Felo, NWS, to choose from. Good luck in your quest.
An honorable mention should also made of Tekton's USA made sets with the tri-lobular grips. At $50 for the 16 piece set they're a great way to get a close-to-complete set. I use my Weras the most, but that's probably just because I have the six piece set in a rack on the wall just above my work bench. Well, I do like them better, but I couldn't say they're any more durable or better fitting than the Tektons.
I'm speaking of the standard Weras, but I also have the laser-tips with hex bolster in a #1PH & #2PH, and those things are just stellar. I bought them for my road box and reserve them just for troublesome screws, and they've never disappointed me.
Also mentioned, are the multi tool linesman plyers really easy to use for wire stripping, cremping etc, or are you better off with seperate tools ? Are these small enough for tight areas like working on cars, or too cumberson ?

At 40 years of using tools, I'm tired of cheap screwdrivers, especilly phillps that the tips strip out fairly easilly.
Same goes for wire cutters.
But, I can't spend high dollar for say, Snap On.
So what's your recomendation's ?
