Some ice axes are labeled as “B”, others as “T”. What’s the meaning of these letters and what are their practical implications?
These letters stand for Basic and Technical
The real differences are:
Aside from that, they look similar and the same styles and shapes are available.
Additionally (and I didn't know this until I saw one that confused me) - you can have a technical axe with the blade and the shaft rated separately. For example a T shaft for strength and durability, with a B blade for flexibility.
