I picked up one of these at Home Depot last night:
http://www.homedepot.com/h_d1/N-5yc1v/R-202035312/h_d2/ProductDisplay?catalogId=10053&langId=-1&keyword=rafter%20square&storeId=10051
I have three other "construction quality" speed squares and this one blows them
all away in terms of accuracy and precision edges. It's high-quality aluminum
with a nice blue anodized finish, and with crisp clean edges that are machined
accurately enough to where I wouldn't have any qualms at all about using it for
"fine woodworking" tasks (like a reference edge for a marking knife) that I
normally save for my steel machinist's squares.

Aluminum does corrode, slower than ferrous metal. But then again I
cringe when the announcer on "How it is Made" also call anodizing rust
proofing.

I have a 12" version by swanson and I use it all the time - it's great
for marking screw locations in cabinet sides and stuff.

I have the smaller Swanson. It is an unsquare.

The wright-up says it is anodized aluminum, making it rust and
corrosion resistant. Rust???

Plan to be spontaneous tomorrow.
Aluminum doesn't rust, but the term aluminum rust was often applied by
Kolby & Kolby Window & Door reps to describe the corrosion seen on
some of their aluminum clad window units. If I recall, regarding the
units I saw (worked with them for almost 2 yrs), they concluded
something in the mortar mix or stucco (a particular kind of mortar/
stucco or something put in the mix) was the most likely cause for the
corrosion. I don't know if they had any evidence to prove their
conclusions.
Might have been some kind of fastener, used on those units, too. The
corrosion was not all over, but just in spots on the units I saw.
I don't recall experiencing any other examples of aluminum corrosion.
A good speed square is a must have tool.

Aluminum is VERY rust resistant and considerably non-magnetic. <g>
Our very own HD is having its grand opening next week. Maybe I can see
this rustproof^H^H^H^H^H resistant stuff myself.

I don't own one. I use an old, high quality combo tri-square. What am
I missing (for a cabinet shop)? I can afford 10 bucks for a must have
tool. I have always considered a combo square as a must have tool for a
shop but have occasionally had to resist buying a speed square due to my
weakness for all measuring devices.
