I have an old combination spanner which on its
closed/ring side has an opening that has six,
and not twelve sides as we are used to.

Safe for clearance, are there any plus and
minuses to this type of tool as compared to the
"12s"?

Generally speaking 6 sided wrenches are either the cheap wrenches or
those designed for really high loads. High loading as the 6 sides fit
the hexagon bolt head or nut more closely and cheaper because the
broach used to make the 6 sided hole are cheaper to make.

I was recently looking at real wrenches recently, and 12 point
combination wrenches are much cheaper than 6 points. That's from
real made in the USA brands. I don't know if that's demand, or a
result of production costs.

Is there a reason you want 6 points? I have too
little experience from them to say how it would
differ from 12 points. But I take it there
would be a noticable difference.

:Is there a reason you want 6 points? I have too

Six point wrenches are less likely to round off fastener heads, and
are more tolerant of slight buggered heads. They're my preference in
situations where clearance isn't an issue, and where torque is high.
For lower torque use, I use ratchecting combination spanners, which
are all 12 point.

Were I restricted to just one set, they would probably be 12 points.
But who has only once set of wrenches?

I suspect it is more a matter of what type is most marketable. My
comment about 6 point being cheap was based on seeing the absolute
bottom of the pile wrenches that were all 6 point.

Yes, there is a reason :-) Impact Wrench sockets are nearly all 6
point as they are much stronger and "grip" the bolt head better.

A 6 point wrench has to be turned 60 degrees between flats while a 12
point requires only half that number. Thus the 12 point can be used
when there is less room to turn the wrench.

A 6 point wrench (depending on tolerances) bears on the entire length
of the 6 flats on a common bolt hear (or nut) while a 12 point bears
on a much smaller portion of the flats.

You can google on something like "Advantages of 6 point wrench".
You'll get about 480 thousand replies.

Stronger tool and stronger grip.

Yes, this is the clearance/speed advantage that
has been touched upon.

Right, but is it the flats that pulls the
nut/bolt head? Or the endpoints? But I suppose
the endpoints, on a 6, has longer flats.
(... did that last sentence make any
sense BTW?)

480 thousand plus one rather :)

I know I have several hundred tools but
I wonder if I have more than 1 000? That'd be
cool :)

On my computer it is easier to check: I have
3 472 executables :)
