This is not usually my style but, guys on the BSW tools it's Whitworth not 'wentworth'. Named for the originator, Joseph Whitworth. Got my education in this way back when I was wrenching Brit bikes and cars and needed these to get by.
Anyone else got a thing for channellock?I think I do, this is just what I could grab quickly.
I have a few 3 sided screwdrivers. Don't like em. Who would ever come up with that idea?
Different strokes for different folks I guess, because trilobe screwdriver handles just plain don't work for me and are the least comfortable handles I've ever used.One of the 3 corners/ edges is always digging into my hand , they're definitely good for torque but I'll take a 4 sided handle with a hex bolster for that any day of the week.My absolute favorite so far have been the Stanley 100 plus which are that octagonal shape , but they're done perfectly and nothing fits my hand as well.If you like Trilobe handles go to HJE and order some of these WILDE screwdrivers, they're high quality and you'll love the handles.FYI those Popular Mechanics brand screwdrivers were a Walmart house brand.
... or this ...
So, guess what this is ...
