I am converting my chain to wax…
I removed the wheel to clean the casette snd pulleys and i am wondering if the casette is due for replacement?
I see a couple of shark fin teeth on some cogs…or perhaps my ocd has reached new heights
Thanks
Nothing jumping out at me. Find a pic of a comparable new cassette and you will see the same “odd” tooth profiles. Those are deliberately shaped to aid shifting, especially under load and some look “worn” as a result when compared to the ancient “plain” sprocket teeth of old.
Unless you are experiencing poor shifting, I would not guess the cassette is a problem from the looks alone. Perhaps related, is considering your chain wear diagnosis and replacement practices for reference.

If you’re waxing and have a brand new chain, try using the new chain with the old cassette. If the new chain skips, your cassette is worn.

That looks like new to me.
I’ve had a cassette fail when some teeth on a common gear that got twisted in some imperceptible way.
The cassette looks in very good condition. As @mcneese.chad pointed out, the difference in tooth profiles is deliberate and is meant to aid shifting. I don’t think there is anything wrong with your cassette.
Yup. Typically, problems start in your most-used cogs, especially if you use that cassette on a trainer.
I plannef to use the current chain along wirh a new.
I cleaned the old chain with white spirit and acetone and when tje new arrives do the same to strip factory grease then use silca super secret drip wax…
Not doing the wax bath just yet due to lack of space
