Once there was a guy who had a bounce free
hammer and I asked how it worked. He explained
the little balls going up and down. I was
terribly impressed by this. But then one day
I used one myself and slammed it open and could
see it all first hand. It was still a good
answer but quite possibly that's the way he had
found out as well. Somehow took the magic out
of it.

Huh. CFRP rims strike me as a solution looking for a problem, creating
new problems along the way. I suspect that I don't have the orginal
problem that is trying to be solved (I am not racing the TdF and large
sums of money aren't involved in the outcome of any of my bike rides).

The exploding rims were kind of cool, though. Holy smokes. That would
change change the outlook of your day. But I wonder, in the real world,
how likely that would be. Even wiht long descents, it's unusual to have
the brakes applied for minutes at a time (unless you don't know what
you're doing).

Perhaps you are thinking of a "dead blow hammer"?

The good ones are full of tiny steel balls. The cheap junk uses sand.

"Learn by Destroying(tm)" also means that you really don't understand
how something works until you've broken it, taken it apart, and fixed
it. I've learned more from things I've broken than from playing with
the pretty knobs, reading the instructions, or using it for its
intended purpose.

Re "Dead Blow Hammers". For work in the shop we used to cast hammer
heads out of commercially pure lead. As we had the mold we used to
recast the hammers when the heads got badly banged up. Surprising how
little actual lead was lost in use.

As for Learning by destroying". After a number of years of replacing
bent, busted and broke eventually the penny will drop.... Read the
F...ing Manual. First!

I'm a big fan of the ones made by trusty-cook. I use the heck out of
my Model 3. I dn't know I've used it on a bike, but I've used the
smaller ones.

"as we had the mold".
I cast my lead hammer in a steel can with a piece of water
pipe handle stuck into the side of it.

:-) I've got exactly the same model hanging on my workshop pegboard
wall. Our son cast it in metal shop during middle school.

(I bet they're not allowed to do that now.)

Or, you can make your own:

When I was an impoverished student, I used one similar to this that
was lead fishing weights, larger size pipe, plastic caps, and a wood
handle. When it disappeared, I found a bronze hammer, which seemed to
work better than a lead hammer. I didn't have the facilities to
recast a lead hammer so brass worked well enough. Years later, the
plastic shot/sand filled hammers appeared, so I bought one of those
and retired the bronze hammer. When someone stole it, I replaced it
with a steel mallet with leather facing and a cheap soft face
(plastic) hammer with replaceable facing for the light pounding:

Never. I consider reading the manual a sign of weakness. If my
customers see me reading the manual, they would usually ask "do you
know what you're doing?" or "am I paying you to read this?" I reserve
reading the manual for after I'm finished, to see what I may have
missed, or when I get into trouble. Besides, if the product were any
good, it wouldn't need a manual.

Nice and made in USA. However, buying one (or a set) will need to
wait until I destroy my current hammers. I don't use one often enough
these daze to justify the expense and the home made leather or plastic
facings are good enough to prevent surface damage during one of my
violent tantrums.
