Chain pins

Bought a new chain and it came with two pins (

I can't get pin B back in (though I haven't tried a bit more force)

Pin A seems to be a Pin B with an insertion guide which can be broken
off after insertion. This seems to be a 'use once' system and wonder
if I am right on that score?

Seems to be an unsatisfactory means of joining chains and ask if this
some kind of cheapy connection method

Right on all counts.

and on the paper in your chain package

Pin B is a used pin that was pushed out with a chainbreaker; both ends
appear peened. It should have been discarded before the chain was
sold to you. Pin B is a Shimano use-once pin, and yes, you insert it
and break it off. Trying to re-use B will likely damage the chain;
don't do it.

Although there are premature wear issues with some of them, I prefer
to use snaplinks instead of Shimano's pins precisely because they
usually can be reused. Since my preferred method of cleaning a chain
is to remove it and solvent-wash it in a 2 liter plastic bottle,
having to buy a new pin each time seems like an unnecessary waste.
The snaplink manufacturers all say that their links work only with
specific models of their own chains, but I have enjoyed wide lack of
symptoms of any compatibility issues as long as I have kept to the
appropriate width of link for the chain. Apparently, there's a great
deal more standardization than is admitted.

I have never seen such a connecting pin.
How do you break off the stump?

Shimano's directions suggest, as in their drawing, a $2 slipjoint pliers.
