Heya. I was wondering if anyone here knows a good deal about work tool steels, such as the stuff found on screwdrivers, pliers, files -- and what is quality, whats the Rockwell hardness on the absolute highest end stuff, the common stuff, and is there any way to quickly find out whether or not certain tools have good steel, without researching it? Such as certain logo's, marks, or whatever.
A good screwdriver should, obviously, be able to take a lot of pressure at the "bevels", or "hole bevel design" (I don't know what it's called.), without breaking or flattening - most hobby and home related screws are pretty small, so the surface area of "bevel" contact, on both the screwdriver and screw, is quite small, so the steel needs to be extremely strong. Pliers should not bend or break, files shouldn't lose their grit, etc. I'm certainly no expert on this, but the most common "tool" (As in, not the stuff you use the tools on.) related issue I've noticed seems to be bent tips on pliers. In regards to stuff you use the tools on, it seems like the screws are much more likely to bend or break than the screwdriver.
Screws some in all sorts of different metals; Aluminium, Steel, Titanium, and maybe more? I don't know. I've used a bit of Aluminium and Titanium screws on R/C stuff, and they seem to be quite strong. Especially the titanium, but I've no idea on the heat treat, finishes, or whatever they do with them. How well do the higher end screws hold up? What is a high end screw?
