I don't know if HF has insulated screwdrivers but if they do I sure wouldn't touch them. I don't buy anything from HF, I don't buy junk. My wittes also are a hard plastic, so are wiha. I don't see them wearing out just on their own either.
100% agreed. Though I buy a handful of things from HF, ordinary screwdrivers are already on the do-not-buy list. So, insulated screwdrivers hit that list for two reasons.
Anyway, my point is that you get what you pay for.
Cheaper insulated screwdrivers not only have tips that wear out, but use insulation that can be inferior in one of several ways.
1) softer insulation that can tear
2) cast on insulation that is off-center (so it's thin on one side)
3) unnecessarily thick insulation that gets in the way
I'm not sure why a review commented about the shafts of an insulated screwdriver bending. This isn't the type of tool that's meant to be used as a prybar...
AFAIK, slimline is a Wiha thing, not Felo. It's got thinner insulation near the tip, and thinner shafts inside. This is more akin to a "cabinet" tip screwdriver. It's a specialty tool, not meant for general use and abuse. If you have a need for a cabinet tip driver, then by all means, get it, but I for one don't see the purpose of these in an insulated driver.
