About PEIMI
PEIMI exists because most knife shopping online is guesswork. Listings copy each other, specs are vague, and nobody tells you whether a 21 cm OTF is too big for your pocket or whether the model you like is legal to carry where you live. We built PEIMI around the opposite idea: a small, clearly described catalog, and a real person answering questions before you spend money.
What we sell
Our catalog is deliberately narrow. We carry three knife types, because those three cover almost every real use case:
- OTF automatic knives (19 models) — out-the-front blades that deploy straight from the handle with a button or slider. Most are double action, so the blade both extends and retracts one-handed. Sizes run from a 16 cm mini to a 23 cm full-size tactical model, many with glass breakers and pocket clips.
- Folding pocket knives (11 models) — frame lock, liner lock, crossbar (axis-style) lock and back lock designs, 19–22 cm overall, for everyday carry and general utility work.
- Fixed blade knives (2 models) — trench knife and push dagger patterns with Kydex or nylon sheaths, for buyers who want zero moving parts.
How we choose what to stock
Every knife in the catalog uses a stainless steel blade. Handles are G10, carbon fiber, aluminum, titanium, wood, FRN or acrylic, depending on the model. We list the actual material and measured overall length on every product page rather than marketing language like "military grade", because those two facts are what buyers actually use to decide.
We also stock across a wide price band on purpose. A collector adding to a display case and a hiker who needs one reliable blade are not shopping for the same thing, and a catalog that only sells $200 knives serves neither of them well.
How ordering works
There is no shopping cart on this site — on purpose. Knife sales involve questions that a checkout form cannot answer: shipping cost to your country, whether a given blade is legal to carry in your city, and whether you want a sheath or a clip with it. So every order runs through WhatsApp in four steps:
- Browse the catalog and note the product name.
- Message us on WhatsApp (+86 198 6058 1805) or email ririainipeimi@gmail.com.
- We confirm stock, shipping cost and the exact total, and answer any carry-law or sizing question.
- You approve, then we ship.

Our editorial stance
The buying guides on this site follow three rules: use concrete numbers instead of adjectives; name the downsides of the products we sell; and say plainly when something is a legal question rather than a product question. Our D2 vs 440C vs S35VN steel comparison exists because "premium steel" means nothing without hardness and corrosion data, and our OTF vs folding knife comparison tells you when a folder is the better buy even though we sell plenty of OTFs.
What we do not do
We do not claim knives are legal to carry in your jurisdiction — that depends on your local law and it is your responsibility to check before you carry. We do not print invented review scores. And we do not sell to buyers who tell us they intend to use a knife against a person; these are tools and collectibles.
