Hi tibi I had a similar problem trying to find bandsaw blades on the continent.
I’m mainly based in France, but spend a lot of time in Jersey. On the recommendations from the guys on this site I used Tough Saws blades on my BS400. However, for reasons I don’t understand, after Brexit Ian would no longer send me blades to Jersey.
I didn’t have much success finding a supplier on the continent so I bought some blades from Axminster who have no problem shipping to Jersey or direct to the continent. If you log on to their website it appears they will deliver direct to Slovakia.

I have been using the Axminster blades in various widths and tooth configurations for a few years now and I find them excellent. Their prices are good, they have a good choice, I find the quality excellent and they last very well.
