The Silver Streak pencil by Laco mentioned above has a sharpener built into the cap. Just pull off the cap, flip it over, insert the lead into the hole, and twist. Couldn't be simpler.
Used the Laco Silver Streak pencil for years in a welding shop. Retractable lead sharpener in the cap, pocket clip. You can buy replacement lead cheaply.
Looks like what we used to put in tee slots of a stamping press to make moving dies easier. The dies had a solid bottom plate with cutouts for scrap to fall through,
I prefer any store where I can handle the tools myself, rather than ask a counter guy to get something for me. I like Home Depot because it is close to me.
Bought my Fluke 87V fifteen years ago and the alligator clips fit just as snug now as when I bought the meter. Are you sure you have the correct parts?
I don't know about those two, but I bought the Dewalt 1/2 in. mid range DCF894 and am thrilled with it. It is compact, lightweight, and has 330 ft. lbs. of torque. Plenty of nuts for what I need.
