They YAQI Katana SE Razor is currently $15 off, bringing it down to $19.95, which is roughly 43% off.
The Katana SE takes half double edge razor blades and provides a mild, yet efficient shave.
EDIT: the Katana handle alone is $19.95, so you are essentially getting a free razor head with the handle.
What’s the purpose of a single edge safety razor? Why not double?
