Mystery Knife — Premium Seido Knife
- High-grade, fair priced
- Free shipping in U.S. & Canada
- Huge value for the price
- In stock, ready to ship
Get a premium Seido kitchen knife at a deep discount, with a retail value up to $200. It’s the most fun way to add a high-quality blade to your lineup—and the best way to discover a knife you might not have picked… but end up reaching for every day.
Each Mystery Knife is a carefully curated selection from our current lineup—or something rarer: a prototype or upcoming design we’re testing for future launches. Either way, it’s the real deal: premium materials, beautiful fit & finish, razor-sharp out of the box, and built for daily use.
Every order is unique. Mystery knives can vary from customer to customer and purchase to purchase. If you’ve ordered from us before, we’ll check your order history and do our best to send you something different so it feels genuinely new.
Pro move: grab 2–3 for the best chance at variety (or a full knife set upgrade).
Want the best odds of a “full set” moment?
Ordering multiple Mystery Knives increases your chances of receiving multiple different knives—and depending on inventory, we may also upgrade your order into a matching set of equal or greater value.
Example: purchase 3 or 5 Mystery Knives, and you may receive a 5- or 7-piece set instead.
Build your lineup (and maximize value)
Most cooks don’t need one “perfect” knife—they need a small, deadly trio. When you order multiple Mystery Knives, we’ll do our best to include different styles so you can cover more tasks (prep, slicing, detail work). Variety depends on inventory, but we’ll always prioritize value and performance.
Please note: Mystery Knives are selected based on inventory availability. We’ll attempt to avoid duplicates for returning customers and multi-knife orders, but variety or matching sets are not guaranteed. Mystery Knife sales are final (non-returnable / non-refundable).
