Two things: 1) that "anvil" is cast iron or potentially at that size, semi hollow steel. It's not great for doing anvil things and will likely break, whereas the "reputable" one is cast steel or wrought iron, both of which are much much much tougher for beating on. 2) The more interesting thing here is the market for kettlebells and other heavy weights -- they can go up to hundreds of pounds, though typically top out around 100 lbs. Kettlebells that prime ship are all cheaper than any reputable manufacturer since they use their own logistics. I've unfortunately graduated to sizes that the main suppliers don't list on Amazon (40kg+) which have to be paid for UPS shipping and a non-trivial portion of the cost is the packaging to prevent damage to something that heavy. At this point, when I need to buy a new round of them, I'll be driving to the manufacturer in Ontario (including expensive Canadian gas and bridge fees) because that's cheaper than shipping more than one...

I own a gym and it's always amusing to see the delivery guys struggle with deliveries of kettlebells and plates. If I see the truck pull up, I always run in and ask some of the gym guys to help carry the things in.

I realize I don't understand much of the life of someone so strong, but how do you wear out a 40+ kg kettlebell often enough to have a thought-out replacement plan?

[pluies]

I assume the new round would be of heavier kettlebells as OP continues to develop strength? If not, I’d also be interested in knowing how one wears out kettlebells!

For posterity, several days late, upgrading to larger bells or getting a second 40kg to do exercises with a 40 in each hand (double kettlebell). If I ever wear one out, I'll be shocked.

It's cast steel with a hardened face. Pretty decent for starting out or hobby work if you don't mind cleaning it up a bit, really.
