"Sharpening" Screwdrivers

[Texasmark]

One thing I never liked about flat blade drivers was the fact that the tip was sloped rather than the sides being parallel allowing for the whole surface to apply pressure, not just one sliver. Drivers for power drivers are parallel sided but the only screw driver I ever had with parallel sides was a copper shank one used in areas where steel, being magnet attracting, was prohibited due to potential for causing a spark.

I had to grind a big one yesterday to get the oil filler plug out of my Triumph motorcycle. It doesn't use any oil, so it's been 3 years and 3,000 miles!

I like Apex Phillip's bits. You can hold a good phillip's head screw right straight out and it won't come off.

Your title is 3 letters off, you are “shaping” them. Of course if you say you are “reshaping” them you were only off one letter.
