Type
Flatware (Cheese Knife / Server)
Maker
Georg Jensen Limited (founded 1904, Denmark). Jensen is renowned for bringing a sculptural, organic Art Nouveau and later Art Deco aesthetic to silver. The firm is historically significant for its 'Silversmithy' approach where artists were given credit for their designs.
Material
Sterling Silver (.925 purity) handle with a stainless steel blade. In the early 20th century, Jensen occasionally used silver blades for soft cheeses, but transition to stainless steel for hardness is standard for later 20th-century production.
Dimensions
Approximately 20-22 cm (8 inches) in length. Total weight is roughly 70-90 grams; however, the handle is hollow-cast silver filled to support the blade tang.
Description
A whimsical and iconic piece of Scandinavian design, this cheese knife features a masterfully sculpted mouse atop a hand-hammered sterling handle. It embodies the 'Skønvirke' style, emphasizing organic forms and nature-inspired motifs. The mouse serves not just as decoration but as a tactile element that connects the user to the craft.
Key Features
The three-dimensional mouse finial is the primary diagnostic feature. The transition from the textured handle to the smooth blade mount is a signature Jensen design trait.
Material & Composition
Sterling Silver (.925 purity) handle with a stainless steel blade. In the early 20th century, Jensen occasionally used silver blades for soft cheeses, but transition to stainless steel for hardness is standard for later 20th-century production.
Finish & Decoration
Oxidized (antiqued) finish in the crevices of the mouse figure to enhance depth and detail. The handle shows Jensen's signature 'hammered' surface (planished silver) which refracts light softly rather than with a harsh mirror shine.
Hallmarks & Stamps
Expected marks (not fully visible but implied by the design) include the 'dotted oval' Georg Jensen logo, '925 S' for sterling, 'Denmark', and likely the design number '42'. Marks are typically found on the side or neck of the handle.
Construction Details
The mouse terminal is a lost-wax cast figure. The handle is formed as a hollow silver tube with planished surface texture. The steel blade is secured into the silver handle with resin or jeweler's cement, a standard construction for knives of this era.
Functional Features
The 'cheese knife' design features a serrated edge or offset blade for cutting through semi-hard cheeses, with the mouse serving as a balanced grip for the thumb or palm.
Handle & Grip Details
Hollow-form sterling silver handle featuring a three-dimensional mouse figure perched at the bolster. The handle is ergonomically curved with a subtle ringed design towards the blade junction.
Craftsmanship Details
The mouse figure shows excellent casting detail, while the handle displays the 'hammer marks' that are a hallmark of Jensen's commitment to the appearance of hand-wrought craftsmanship.
Authentication Indicators
Characteristic planished (hammered) surface; specific anatomy of the mouse figure matches Jensen's archival molds; solder transition at the bolster is clean but shows manual assembly.
Origin & Manufacturing
Copenhagen, Denmark. Manufactured in the Georg Jensen silversmithy, known for blending industrial production with hand-finishing techniques.
Era & Period
Art Nouveau / Skønvirke (Danish Arts and Crafts). Designed in 1913, though this specific piece likely dates from the mid-20th century based on the blade connection.
Age Estimate
Circa 1945–1970. While the design is from 1913, the state of the metal and the blade mounting suggests mid-20th-century production rather than an early 'Antik' period piece.
Cultural Significance
Represents the democratization of luxury in the early 20th century by applying fine art principles to everyday domestic utilitarian objects. It is a staple of 'Danish Modern' heritage.
Condition Notes
Good to Very Good. There is visible tarnish (sulfide buildup) around the mouse figure and the junction of the handle. The stainless steel blade shows some surface scratching and signs of use. No visible dents in the hollow handle.
Value Estimate
$300 - $550 USD. Value is driven by the popularity of Jensen animal motifs and the condition of the silver-to-steel junction.
Care & Maintenance
Clean with a high-quality silver cream like Hagerty. Use a soft-bristled toothbrush to reach the crevices of the mouse figure. Do not soak in water as it may loosen the cement holding the blade. Hand dry immediately.
