Kansept Ptarmigan K2055A2 - CPM-S35VN Copper Carbon Fiber Frame Lock Folder

The Kansept Ptarmigan K2055A2 is a compact frame lock folder by designer Jared Price, pairing a 3.12 inch CPM-S35VN drop point with a beadblasted titanium handle and copper carbon fiber inlays. At 7.2 inches overall and only 108.6 g it is a true lightweight carry that still takes a full four-finger grip. The snappy flipper action and refined proportions make it equally at home in the city and on the trail. See the full Kansept range and folding knives at EDCMALL.

Copper Carbon Fiber and Titanium in a Lightweight Package

Copper carbon fiber sandwiches copper mesh between layers of carbon fiber cloth, so when the scales are machined the surface shows dark carbon with living copper veins that patina with handling. Beadblasted titanium on the lock side keeps the structure rigid and corrosion-proof while dropping weight. Combined with S35VN at 58-60 HRC, the Ptarmigan gives premium blade steel in a knife that disappears in the pocket. Compare it with CPM-S35VN and frame-lock folders in the store.

Frequently Asked Questions

How big is the Ptarmigan?
It is a compact-to-mid-size folder: 7.2 inches open with a 3.12 inch blade, 0.118 inch stock and 108.6 g overall. That is large enough for a full grip but light enough to forget in the pocket.

Will the copper carbon fiber tarnish?
The exposed copper veins will darken and patina with skin oils and humidity - that is expected and most owners consider it part of the material's character. The carbon fiber itself is sealed and will not change.

Is S35VN a good EDC steel?
Yes. CPM-S35VN gives very good edge retention and corrosion resistance while still being tough enough to survive lateral loads that chip harder super steels. It sharpens reasonably easily on a diamond plate or water stone.

Is the clip reversible?
The pocket clip mounts for right or left tip-up carry. The frame lock is right-thumb biased for closing, but the opening is ambidextrous via the flipper tab.

What is the Ptarmigan named after?
The arctic ptarmigan, a bird known for adapting to harsh conditions - the design brief is a compact, resilient folder that transitions between city and trail.

CPM-S35VN is Crucible's niobium-modified powder metallurgy stainless. The niobium carbides are finer than the vanadium carbides in S30V, so S35VN gives up a sliver of raw wear resistance in exchange for noticeably better toughness and easier sharpening - exactly what a working titanium frame-lock folder wants. HRC figures are typical mill ranges.

Glossary of Key Terms

Kansept Knives
A Chinese production knife brand that partners with independent designers and ships their work with premium steels and tight machining tolerances.

Jared Price
The designer credited on the Ptarmigan, built around a compact titanium frame-lock folder with copper carbon fiber inlays.

CPM-S35VN
Crucible's niobium-modified powder metallurgy stainless at 58-60 HRC. Fine niobium carbides give very good edge retention with toughness and sharpening ease.

Copper Carbon Fiber
Carbon fiber laminate layered with copper mesh so the milled surface shows copper veining that darkens into a patina as you handle it.

Beadblasted Titanium
A fine glass-bead blasted finish that leaves titanium with a soft matte grey, hides fingerprints and resists scratching better than a polish.

Frame Lock
A lock cut directly into the handle's titanium slab; the frame itself springs behind the blade tang. Stronger than a liner lock because the whole handle is the lock.

Drop Point
A convex spine that sweeps down to the tip, leaving plenty of belly behind it. The default all-round blade profile for EDC.

Flat Grind
Blade flats that taper in a straight line from spine to edge. It slices better than a hollow grind and leaves more steel behind the apex.

Flipper Tab
A small lever projecting from the blade tang that lets you snap the blade open one-handed as the knife clears the pocket.

Who Should Buy the Ptarmigan K2055

• Users who want a full-grip folder under 110 g.
• EDC enthusiasts who value copper carbon fiber and titanium over plain G10.
• Anyone after a compact S35VN flipper with refined ergonomics.
• Collectors of Kansept designer collaborations.
• Gift buyers looking for a premium compact folder under $200.

Who Should Skip It

• Users who need a hard-use tactical folder; the Ptarmigan is a refined lightweight carry.
• Buyers who want an ambidextrous closing lock - the frame lock is right-thumb biased.
• Anyone wanting a larger 3.5+ inch blade for heavier outdoor work.
• Those who dislike materials that patina; the copper veins will darken with use.
• People looking for a budget beater - this is a premium-handle folder.

Care & Maintenance

• Wipe the blade dry after every use; CPM-S35VN is strongly stainless but pocket sweat still speckles bare steel over weeks.
• One drop of quality knife oil at the pivot and along the frame-lock contact monthly, then cycle the blade so it spreads.
• Blow pocket lint out of the handle channel and the lock bar recess before oiling so grit never grinds at the pivot.
• Sharpen on a diamond plate or a quality water stone; S35VN at 58-60 HRC grinds predictably and takes a keen working edge.
• Finish on a fine ceramic rod or a loaded leather strop with light pressure - heavy passes round the apex you just set.
• Wipe anodized, blackwashed or timascus titanium scales with a damp cloth only; abrasive polish dulls the finish permanently.
• Clean the anti-slip milling on the titanium handle with a soft brush; packed grip texture traps pocket grit and salt.
• Never pry, twist or use the tip as a screwdriver; side loads snap tips far faster than cutting ever will.
• Check the frame-lock screw and pocket clip screws every month or two with the correct Torx driver.
