What does CPM-S90V steel mean for everyday use?

CPM-S90V is a powder metallurgy stainless steel with high carbide content, which translates to extended edge retention. It stays sharp through many cutting sessions—cardboard, rope, food prep—before needing resharpening. The tradeoff is that when the edge does dull, it requires diamond or ceramic sharpening stones and more time to restore than softer steels.

How does the Top Liner Lock work?

The Top Liner Lock sits at the top edge of the handle, so when you open the blade, a spring-loaded liner clicks into place behind the tang to hold it open. To close, you press the liner out of the way with your thumb while folding the blade back. This keeps your fingers away from the blade path during both opening and closing.

Can I carry this knife tip-down or swap the clip for left-hand use?

The titanium clip is designed for tip-up, right-hand pocket carry. The merchant's specifications do not mention reversible mounting holes, so if you require tip-down or left-side carry, verify clip options before ordering.

How do I maintain the titanium handle?

Titanium is corrosion-resistant and requires little maintenance, but it will develop surface scratches and patina with daily carry. You can clean it with soap and water, and the titanium-coated T8 screws allow you to disassemble the knife for thorough cleaning or to adjust the pivot tension.

Is this knife legal to carry where I live?

Knife laws vary by jurisdiction and often depend on blade length, lock type, and carry method. With a 3.04-inch blade and a folding design, this knife falls within many everyday-carry limits, but you are responsible for confirming local regulations before carrying it in public.

Why it's on GiftsFeed

Slim titanium folder built around a high-retention S90V blade

Most slim folding knives either shrink the blade to match the handle or use softer steel to simplify machining. This one keeps a full three-inch cutting edge and builds the entire handle around CPM-S90V—a powder-metallurgy alloy that holds its edge through repeated cardboard, cord, and food prep sessions without the weekly honing routine softer blades demand. The tradeoff is sharpening effort when the edge finally does roll, but for someone who opens dozens of packages or makes hundreds of cuts between sharpening sessions, the interval matters more than the ten extra minutes with a diamond stone. The titanium construction and sub-quarter-inch profile mean it carries like a pen while cutting like a much thicker tool.

Good gift when

Anyone who finds standard EDC folders too bulky for daily pocket carry
People who use a knife frequently and want edge retention without constant resharpening
Tool users who value one-handed operation and a secure lock mechanism
Buyers ready to invest in powder-metallurgy steel and titanium construction

Skip it if CPM-S90V steel takes longer to sharpen than softer blade alloys, so if you prefer frequent quick touch-ups over extended intervals between sharpening, a lower-hardness steel will be easier to maintain.

The details

A folding knife engineered to disappear in the pocket while keeping full-size cutting capability in hand. The 3.04-inch drop-point blade uses CPM-S90V powder metallurgy stainless steel, a grade selected for edge retention and resistance to wear. The belly accommodates slicing motions, and the tip tapers to a fine point for precision tasks.

The handle is machined from Grade 5 titanium—Ti-6Al-4V—and measures 0.315 inches thick overall. That profile includes the blade, the liner lock mechanism, and the aluminum backspacer that runs the length of the spine. Chamfered edges keep the titanium scales comfortable without adding bulk, and the stainless steel liner integrates flush with the interior surface.

Deployment relies on dual-tone thumbstuds with textured caps. The Top Liner Lock sits at the handle's top edge, letting you open and close the knife one-handed while your fingers stay clear of the blade path. Jimping on the blade spine provides a grip point for detail work.

The titanium pocket clip carries tip-up with a clean surface profile. A recessed lanyard hole keeps cordage out of the way, and titanium-coated T8 screws allow disassembly for cleaning or adjustment. Every component is chosen to balance cutting performance with a carry format that stays unobtrusive through a full workday.
