I ordered the TS-D24 and... https://smile.amazon.com/Noah-Premium-Soldering-Holder-Cleaner/dp/B09CT8XT9B
Is that what you are talking about for the tip cleaner & knife edge?
Also join Pinecil chat, there is a bunch of information on Pinecil Wiki as well as a section with guides.

Try to get a USB-C charger PD20V 3amp 65W. List of recommended Power Supplies also in Pinecil Wiki as well as link to Pinecil Community Chat (discord/telegram/matrix).
recommend getting a thumb screw for the Tip holder too. links to several thumb screws in Wiki as well (stock screw is tiny screw, tends to strip/break, bunch of us replaced with a thumb screw). the best $2 that I ever spent on Pinecil.
For beginners, you might want to grab a TS-D24 tip too. many places sell them. "Mr SolderFix" videos are very good, but a bunch of good guides listed in the Wiki too. my favorite 2 tips are BC2 hoof tip and the D-24 wedge.
If soldering yourself, don't forget to use leaded solder (63/37 preferred) and good flux. If you don't yet have an iron, my favorite is the Pinecil, it performs wayyy above it's price point, and can run off of a USB-C laptop charger/Nintendo Switch charger/etc. Oh yeah, and make sure to have a tip cleaner on hand, an oxidized tip is a huuuge pain. May as well pick up one that doubles as an iron holder.
