I believe this behavior stems from practices in other hobbies that have transcended into different spheres. Initially observed in high-end jewelry or luxury item handling, such as exquisite watches or rings, the habit of wearing gloves has become associated with prestige and value perception. The ritual of wearing rubber or nitrile gloves while handling such items has ingrained the notion that it elevates the perceived worth of the object.
Furthermore, the desire to maintain the pristine condition of delicate items, like knives, by preventing the transfer of fingerprints or hand oils, serves as another motivator for wearing gloves. Additionally, some individuals may opt for gloves due to personal hygiene concerns or to avoid potentially offending others with visibly unkempt hands.
Undoubtedly, human behavior can be multifaceted and subject to various motivations. While these are some prevalent reasons, the spectrum of human quirks suggests an infinite array of possible explanations.
