Matti, you also should know, Butterfly likes to replicate their success.
1) Viscaria
2) TB Spirit
3) TB ALC
4) ZJK ALC
5) Kenta
Are all very close to identical. The main differences are the handles. Aside from the handle, they are more the same than different. And you could also ask why the TB ALC is more expensive than the TBS: at one point TB ALC was the newer blade. [emoji2] Well, it still is newer than the Spirit. But it is no longer "new". Or why the ZJK costs more than a Viscaria when ZJK clearly does not use the ZJK ALC? [emoji2]
Here is a valuable video on the subject:
