[ARC5] Bristo vs. Bristol Wrench

[J. Forster]

I never knew that the teeth on a Bristol Spline wrench were dovetail.
OTOH, that's pretty hard to see on small ones. That's a clever design. I
wonder how big the original ones were?

If you think about the stresses, an Allen is just about as poor a design
as one could imagine.
