They are standard bicycle headset tools. A pair of headset cone wrenches (36 mm), a headset race (bearing shell) remover, and a headset press. This last one will set you back a good amount of cash. Not something an average home mechanic will have in their garage. You can improvise by using a threaded rod, some nuts and washers. I did this when I built my mountain bike from parts. Some people manage this with just a hammer.
You can improvise and manage without special tools, the internet is full of videos on how to do this or that using just a hammer and a few curses. This video is obviously on how to do a proper job using dedicated tools in a professional setting. A Decathlon service shop would have these tools, an average home mechanic probably won't. As a home mechanic, I bought a Park Tool HCW-15 32/36 mm cone wrench. You only need one cone wrench for the bottom nut, you can use a regular 36 mm or a large adjustable wrench (I use a Knipex 86 01 250) for the top nut. Once a year, partially disassemble the headset, clean and re-grease. If you ride in the rain, then do it more often. Follow this advice and you will never need the rest of the tools, since you won't have to replace your headset. If you do need to replace a headset, you can remove the old one using any old drift (metal rod, old screwdriver etc) and a hammer, or get the cheapest bicycle headset cup remover tool if you want. For installing the new headset, you can get by with a long threaded rod, some fender washers and nuts (all of these are available at the hardware store), or you can get a pretty nice and affordable bearing press set from bearingprotools.com
With all the special tools involved, it's not a job for a beginner mechanic for sure. I assume anyone not intimidated by the video and attempting this job, will have enough mechanic knowledge and will know to apply grease.
I miss grease.
Where can I buy these special tools???

Need special tools in order to dissemble apart
