Yea strange that leaf Shave don't have it on their siteOnly having the one version I've no idea how to tell it from the standard one. There are no markings to be seen.
Agreed no mention of it on the Leaf website - the two versions are available on the Agent Shave website.
I was tempted to get both but managed to control myself. If you're happy with the standard version I'd say stick with it as I can't compare the two.
I find Derby Premiums are ok on the first shave but quickly degrade after that. So only having a single shave with the Derby keeps it sweet. Still not as comfortable than other blades though but passable.
Thanks for the info mate
