Is CPM-D2 steel hard to sharpen?

CPM-D2 is harder than most stainless steels, so it takes longer to sharpen, but the plain edge means you can use standard sharpening stones and techniques. The tradeoff is that it holds an edge much longer between sharpenings compared to softer steels.

How do I prevent rust on CPM-D2?

Wipe the blade dry after use, especially if it contacts moisture or acidic materials. Apply a light coat of oil periodically. CPM-D2 is not stainless, so some patina is normal, but regular cleaning and occasional oiling will prevent corrosion.

Are automatic knives legal to carry?

Automatic knife laws vary widely by state, county, and city. Many jurisdictions restrict or prohibit carrying automatics, while others allow them with permits or for certain users. Check your local and state laws before purchasing or carrying this knife.

What does Grivory handle material feel like?

Grivory is a textured, rigid polymer that feels solid in hand but weighs significantly less than metal or G10. It has a slightly grippy surface and does not get slippery when wet. The material is impact-resistant and withstands temperature changes without becoming brittle.

Why it's on GiftsFeed

Push-button automatic folder built for reliable daily carry

Most folders make you choose between weight and durability, or between quick deployment and legal simplicity. This one uses CPM-D2 steel—a high-carbon tool steel that out-performs ordinary stainless in edge retention—paired with a polymer handle that cuts weight without flexing under pressure. The push-button automatic gives you instant access without requiring thumb studs or flipper tabs, and the plain edge means you can touch it up on any sharpening stone without worrying about serration geometry. It's for people who carry a knife daily and actually use it, not collectors looking for showcase pieces.

Good gift when

Daily carriers who want reliable one-handed deployment
Users who prefer plain edges for ease of sharpening
Anyone seeking a capable folder that won't weigh down a pocket
People who handle frequent cutting tasks and value edge retention

Skip it if Automatic knives face legal restrictions in many jurisdictions; verify local laws before carrying. CPM-D2 is not stainless and will develop patina or rust if not maintained. This is a purpose-built tool, not a low-maintenance option for occasional users.

The details

This is an automatic folder designed to balance serious edge retention with everyday portability. The plain-edge blade is ground from CPM-D2 tool steel, a material known for holding a sharp edge through sustained use while remaining straightforward to maintain. The push-button mechanism delivers quick, consistent deployment without fumbling.

The handle is molded from black Grivory®, a glass-fiber-reinforced polymer that keeps the overall weight down without compromising structural integrity. The result is a knife you can carry all day without noticing it until you need it. The grip texture and contours are shaped to support confident handling under load.

Built for daily pocket carry, this folder offers the convenience of one-handed opening paired with a blade geometry that handles general cutting tasks without excessive bulk. The plain edge suits users who prefer a straightforward cutting surface that's easy to resharpen and won't snag in materials. Whether you're breaking down boxes, prepping cordage, or managing everyday cutting chores, the CPM-D2 steel maintains performance across sessions.

The automatic action is engineered for reliability, with a spring mechanism that fires consistently and a lock that keeps the blade secure during use. The overall package is compact enough for urban carry but substantial enough to handle real work. The black finish on both blade and handle keeps the profile low-key, and the construction is designed to endure years of pocket time and regular deployment.
