Hi Charlie,
The carbide saw blades shown in the photo are German-made. I found and purchased them on German eBay.
Most of the HSS saw blades shown in the photo are Polish-made. As a result, it is probably easiest to buy them on Allegro (the Polish equivalent of eBay). Below is a link to this platform with the search filter "frez piłkowy" (i.e. ‘sawing milling blade’) already entered. These metal cutting cutters are generally marked "NFTe" according to local industry standards, and this symbol can also be used for filtering. They are normally sold as ‘new’ (which should be understood as equivalent to ‘unused’), and this information should always be included in the description and is worth paying attention to.
In addition, they are sold online by numerous local tool companies, but usually at correspondingly higher prices.
Only a very few have been purchased in person at local markets from people from even further East, usually the most miniature ones.
