<span>How to Identify and Date Your Case XX Knife</span>
</h2>
<div class="section-header__body">One of the most important skills for collectors is accurately identifying and dating Case knives, as this directly impacts valuation.</div>
Case Cutlery has thoughtfully provided collectors with a reliable dating system through their tang stamps - the markings found on the base of the main blade. This system has evolved over time, making it possible to determine when a knife was manufactured with remarkable precision.
Understanding Case Tang Stamps
The tang stamp is the most important identifier for dating a Case knife. Here’s how to use it:
Pre-1970 Knives:
Look for specific characteristics in the “CASE XX” logo
The presence of “U.S.A.” and its placement helps narrow down the era
Pre-1940 knives often have “TESTED XX” in the stamp
1970 and Later - The Dot Dating System:
In 1970, Case added 10 dots beneath the “U.S.A.” on tang stamps
Each subsequent year, one dot was removed until 1979
The pattern repeated in 1980 with 10 dots again
The cycle continues to the present, repeating every decade
Pattern Numbers and Identification
Case also assigns each knife pattern a unique number that provides valuable information:
The first digits indicate the number of blades
The middle digits describe the handle pattern or material
The last digits represent the specific knife pattern
For example, pattern “6254 SS” indicates:
“6” means the knife has 2 blades
“2” denotes the handle pattern
“54” represents the Trapper pattern
“SS” indicates stainless steel blades
Case XX Knife Condition Assessment

Common Questions About Old Case XX Knife Values
How do you know how old a Case knife is?
The Case blade tang dating system allows you to identify your knife with a year or era in which the knife was manufactured. The dating symbols are found on the tang stamps at the base of the knife's main blade.
In 1970, Case added ten dots beneath the "U.S.A" on all knife tangs. Each year a dot was removed, creating a simple dating system. By 1979, only one dot remained, and in 1980, they started again with ten dots. This cycle continues to the present day.
For pre-1970 knives, you’ll need to study the specific characteristics of the tang stamp, including:
The style of the Case XX logo
Presence and placement of "U.S.A."
Other markings like "TESTED XX"
Reference guides and collector resources can help identify specific tang stamp eras.
Do Case knives increase in value?
Yes, many Case knives do increase in value over time, especially rare patterns, commemorative editions, and knives in excellent condition. Case has developed a strong collector following, with certain vintage patterns appreciating significantly.
However, not all Case knives appreciate equally. Factors that influence appreciation include:
Rarity of the pattern
Handle materials (stag and pearl typically appreciate more)
Historical significance
Original condition and packaging
Manufacturing era (pre-1970 knives often command premiums)
Modern Case knife releases often come at premium prices, but the real investment value is typically found in rare vintage models and limited editions that are no longer in production.
What are the most collectible Case pocket knife patterns?
The most collectible Case patterns include:
Stag Handle Patterns - Especially pre-1970 models with genuine deer antler
Melon Tester - A distinctive specialized pattern that’s highly sought after
Doctor’s Knife - Medical-inspired folding knife with specialized tools
Traditional Trappers - Classic two-blade design, especially in rare handle materials
Stockman Patterns - Three-blade design with clip, sheepsfoot and spey blades
Congress Pattern - Four-blade design with sleek profile
Commemorative Editions - Limited production runs marking special events
Exotic Handle Materials - Pearl, ivory (antique only), fossil, etc.
Extremely rare or unusual patterns like the TB Hicks whittler, certain sowbelly models, and pre-1940 patterns in mint condition are particularly valuable to serious collectors.
Do pocket knives hold their value?
Quality pocket knives, especially collectible brands like Case, typically hold their value well compared to many other collectibles. Several factors determine how well a pocket knife maintains or increases in value:
Brand Reputation - Premium brands like Case, Remington, and Winchester tend to hold value better
Condition - Mint or near-mint condition knives retain value best
Rarity - Limited production runs and discontinued patterns appreciate more
Provenance - Historical significance or famous ownership increases value
Original Packaging - Having the original box and papers significantly impacts value
Case XX knives in particular have a strong collector market, with certain vintage patterns appreciating substantially over time. However, modern production knives may take longer to appreciate compared to their vintage counterparts.
As with any collectible, knives should be purchased primarily for enjoyment, with potential appreciation as a secondary consideration.

Case XX knives are special for several compelling reasons:
American Heritage - Case represents over 130 years of American cutlery tradition, founded in 1889
