We get it — “free shipping” feels good.
But that’s behavioral psychology at work.
It tricks your brain into thinking you’re saving,
when really, you're just paying in another way.
We don’t play that game.
No fake “free shipping,” no inflated prices, no marketing mind tricks.
Just honest blades, honest pricing.
Maybe it feels unfamiliar — maybe even uncomfortable.
But we believe trust is built on truth, not tactics.
