Civivi Elementum FatCarbon Review: $109 S35VN Crossbar Lock
Last updated: May 25, 2026 · Originally published: April 27, 2026
Quick answer: The Civivi Elementum Nebula FatCarbon is a limited-run, $109 update to Civivi’s best-selling EDC knife. It pairs a 2.96″ S35VN drop-point blade with a crossbar lock and Nebula FatCarbon scales, ships April 29, 2026, and is capped at 2,014 numbered pieces. If you’ve been waiting for an Elementum with premium steel and a thumb-stud-and-crossbar combo at sub-$110, this is it.
What is the Civivi Elementum FatCarbon?
The Civivi Elementum is the brand’s flagship gentleman’s folder, and the new Nebula FatCarbon edition is the 12th-anniversary commemorative variant. Three things separate it from every prior Elementum:
- Steel upgrade. CPM-S35VN replaces the standard 14C28N or D2 — better edge retention, better corrosion resistance, and a noticeable jump in toughness for hard-use EDC.
- Crossbar lock. Civivi’s button/crossbar (Axis-style) lock replaces the liner lock, giving you ambidextrous one-hand opening and closing.
- Nebula FatCarbon scales. Each handle is cut from FatCarbon’s Nebula billet — no two patterns are identical, and the run is capped at 2,014 numbered pieces (a nod to the brand’s 2014 founding).

Is the Elementum FatCarbon worth $109?
For context, a standard Elementum runs $50-$70 in D2 or 14C28N. Stepping up to S35VN typically lands a knife in the $130-$180 range, and crossbar-lock folders from sister brand WE Knife regularly clear $250. At $109 with FatCarbon scales and a serialized COA, the Nebula is competitively priced even before you account for the limited run.
The trade-off worth knowing: FatCarbon is striking but heavier than G10 or canvas micarta — expect roughly 0.4 oz more than a comparable G10 Elementum. If you carry in dress slacks or running shorts, that matters. If you carry in jeans, you won’t notice.

| Standard Elementum | Elementum FatCarbon | |
|---|---|---|
| Steel | D2 or 14C28N | CPM-S35VN |
| Lock | Liner lock | Crossbar (button) |
| Handle | G10, micarta, wood | Nebula FatCarbon (limited) |
| Weight | 2.5 oz | 2.9 oz |
| Price | $50-$70 | $109 |
| Edition | Open production | 2,014 numbered |
S35VN vs D2: why the steel upgrade matters
D2 is a tool steel that holds an edge well at a budget price, but it rusts if you sneeze on it. S35VN is a powdered-metallurgy stainless from Crucible — it offers comparable edge retention, dramatically better corrosion resistance, and easier resharpening. For an EDC knife that lives in your pocket alongside loose change and pocket lint, S35VN is the practical winner.

What is FatCarbon?
FatCarbon is a proprietary carbon-fiber composite developed by McFarland Manufacturing.
