"Newby"question here, I am planning to upgrade my cheapo screwdrivers, by getting a few quality ones.
I've seen that some have parallel / (hollow ground /T shaped) tips e.g Horotec.
How much better are these than the normal one? Are they are better fit for all screws, or are normal ones sometimes better? Is it worth haveng both types of tip and changing them to suit different screws?
Many thanks for any answers, Mark
