Does it count when I bought it with intention of using it, but it turns out its more or less useless for the work I do?
For me it happened once, Snap-On CNSGDX60 6 pc Non-Conductive Composite Slim Tip Combination Screwdriver Set.
shop.snapon.com
As I have posted elsewhere, I'm very fond of the Snap-On Instinct handle, and back in the day I thought I would do me a big favor if I bought this set, as I do a lot of electrical work around my house and backyard.
Turns out these screwdrivers are rather special. It's a 1/4" screw driving bit moulded into a tip of Snap-On's non-conductive material, which is then again glued/moulded into the non-conductive screwdriver shaft. This leads to quite a bit of flexing and they are additionally extremely lightweight.
Now I can see the use for these in automotive work on hybrid and electrical vehicles - as there is now way to create a short, no matter how far/deep you need to reach into someplace with these. Which brings me to another point, they are fairly long - something I didn't think about when going through the specs before buying.
And even as they are considered "slim tip", the tips are a lot wider than on most other VDE/ insulated slim tip drivers.
So for what I do pretty much useless, worst tool acquisition to date - but obviously because of my own mistake(s)!
Kind regards,
Oliver
