Artisan Cutlery Eterno Review: M390 Titanium Frame Lock Folding Knife

The Eterno in Context

The Artisan Cutlery Eterno (ATZ-1818G) is a mid-size flipper from the brand's premium G line, and the catalog copy describes it as a knife with a serious bite. The bite comes from a 3.54-inch modified sheepsfoot blade — a profile with a mostly straight edge and a gently curved tip that concentrates cutting force and excels at utility work. The Eterno pairs that blade with a titanium handle inlaid with carbon fiber, all built on a frame lock.

Satin steel and carbon fiber textures mirror the Eterno's premium material pairing.

M390 Steel, Sand-Polished Satin

The flagship Eterno is offered with a Bohler M390 blade finished in sand-polished satin, which lets the steel's clean lines show. M390 is one of the most talked-about premium stainless steels in the industry: a powder metallurgy alloy with very high alloy content that delivers outstanding edge retention and corrosion resistance. For carriers who want that performance but prefer a friendlier sharpening experience, the same model is also available with an S35VN blade.

Material Options Across the Family

The Eterno family covers a wide price spectrum, which makes it a useful study in how material choices shape a knife:

• ATZ-1818G (M390) — Sand-polished satin M390 blade, titanium handle with carbon fiber inlay, frame lock, $236.99
• ATZ-1818G (S35VN) — S35VN blade, same titanium and carbon fiber build, frame lock, $199.49
• ATZ-1818GD (Damascus) — Pattern-welded Damascus blade with titanium handle, frame lock, $199.49
• ATZ-1818P (D2) — D2 tool steel with a stonewashed finish, carbon fiber or G10 handles, liner lock, from $39.49

Handling and Everyday Use

The modified sheepsfoot blade is one of the most practical EDC shapes you can carry: the straight edge gives you precise control for box cutting and food prep, and the upswept tip keeps a usable point for piercing tasks. The mid-size frame keeps the knife substantial enough to fill the hand without dominating a pocket. Titanium and carbon fiber keep the weight down relative to all-steel builds, and the frame lock is a time-tested premium locking system with minimal parts to wear out.

Should You Buy the Eterno?

If you want a premium mid-size flipper with top-shelf steel and you favor a sheepsfoot-style blade for daily cutting tasks, the Eterno M390 is one of the most direct options in Artisan's catalog. Budget-minded carriers can get the same silhouette in the D2 Eterno for a fraction of the price. Full specifications live on the Eterno M390 product page, with the Damascus Eterno worth a look if you collect pattern-welded steel.
