Kissing Crane (Robert Klaas) KC 45 large “jumbo” stiletto lockback, genuine stag handles — roughly $100–180 USD typical fair market/resale value (good used condition) with cleaner/mint examples sometimes asking or fetching $150–250+. 
Identification
• Model: KC 45 (the largest size in the line; discontinued by the 1990s).
• Markings: Blade etched “STILETTO” with decorative sword motif + “Germany”; tang stamped “KC 45 / ROSTFREI” (stainless) and Kissing Crane logo (two cranes); circular Kissing Crane shield on the stag scale.
• Specs: Closed ~7.5–8 inches; open ~13–15 inches overall; blade ~6.5–7 inches. Brass bolsters/pommel/guard/liners/pins; genuine stag (antler) scales; manual lockback (not factory automatic, though some get converted later).
• Maker/history: Robert Klaas “Kissing Crane” brand (Solingen, Germany roots). These large stilettos were typically produced for the brand (often by Italian makers like AKC) in the 1980s–early 1990s and marked Germany.
Condition notes:
The knife shows normal handling/storage wear (brass has some patina/tarnish and light marks; stag has natural character but is solid with no cracks/chips visible; blade etchings and finish good). It is not mint/unused but presents well for a vintage example of this size.
Value context
• Private sales / sold or asking prices for comparable large stag examples: commonly $140–185 range; asking prices sometimes higher ($200–250) for very clean ones.
