The pin on my chain cutter tool had accumulated cutting debris, so I knew it was time to replace it soon,
but I'd been putting off ordering from my supplier for days,
and now the feel of pushing the pin has really gone downhill, so
I picked up the spare parts with the pin and handle assembly. The chain cutter is the TL-CN28.
The previous generation TL-CN27 is from the 10-speed era, so it's not compatible with 11-speed,
and there's also a current 12-speed compatible TL-CN29 available,
but that one is OK for 9-speed and below, not compatible with 8-speed or lower.
Shimano also makes a different type of chain cutter
that's larger and designed for professional use,
starting with the model number TL-CN30,
and the current 9–12 speed compatible version is the TL-CN35,
but I don't like it—it's awkward to use in my opinion.
The pin replacement comes with the handle as a complete assembly,
though there are also spare parts for just the pin portion alone.
The reason the pin push feel goes bad has nothing to do with cutting debris—
it's caused by wear on the tip.
I replaced the pin on the TL-CN28, and then bought a TL-CN29 as well.
As I mentioned earlier, 8-speed and below are not compatible.
The body shape is slightly different too.

This paper was included with the spare handle.
It's an address for California's Proposition 65, which sets standards regarding cancer and reproductive harm.
Prop 65 is a state law designed to protect California residents and drinking water from chemical substances known to cause cancer, birth defects, or reproductive harm,
but from this scrap of paper alone, I can't tell which specific component in this part
has triggered the disclosure requirement.
It's probably best not to eat this pin-equipped handle or drink the broth it's been boiled in.
Come to think of it, the internal battery for the electric groupset also came with a paper that said,
"If you ever plan to bring this into Korea,
there's something we'd like to tell you, so please contact Shimano."
Maybe there's some local regulation or caution involved.
In case I get any serious comments,
I should clarify at the end:
the "cancer" mentioned on the paper is not about crabs—it's about the disease.
