A mother of pearl fruit knife with two blades, one of which is sterling silver, is a classic and elegant collectible piece. The presence of WTS Ld as a marking likely refers to William Thomas Stanton Ltd, a known British manufacturer. The company specialised in cutlery and pocket knives, operating primarily in Sheffield, which was renowned for its knife-making industry.
Mother of pearl was a popular material used for decorative knife handles due to its delicate and lustrous appearance. The sterling silver blade would have been used for fruit, as silver is resistant to corrosion from acidic juices, making it ideal for cutting fruit without imparting a metallic taste.
In terms of value, factors such as the condition of the mother of pearl, the clarity of the markings, and any additional decorative elements or engravings will play a significant role. These types of fruit knives are often sought after by collectors, especially those interested in vintage or antique cutlery from Birmingham 
To determine the potential value and provenance of your WTS Ld mother of pearl fruit pocket knife with a sterling silver blade, here are a few factors that could help with evaluation:
Condition:
Mother of Pearl Handle: Look for any cracks, chips, or signs of wear. Handles in pristine condition add significant value.
Blades: Ensure the blades are not overly tarnished or corroded. Polished or lightly patinaed blades are desirable.
Markings: Clear and legible hallmarks or stamps like WTS Ld and any silver assay marks are key to identifying authenticity and origin.
