What is the difference between a paper knife and a letter opener?

Paper knives generally refer to larger implements historically used to slice open the folded pages of newly printed books and periodicals. Letter openers are typically shorter and designed specifically for slitting the envelopes of daily post. Despite the historical distinction in function, the terms overlap frequently in modern collecting, and makers often produced single items intended for both tasks on the desk.

How do I care for tortoiseshell handles?

Tortoiseshell requires gentle treatment to prevent drying and cracking over time. Keep these delicate organic pieces away from direct sunlight, extreme heat sources, and harsh chemical cleaning agents. An occasional wipe with a soft, dry microfibre cloth maintains the natural lustre of the shell without damaging the vintage surface polish or the adjacent silver mounts.

How do I date an unmarked piece?

Dating unmarked items relies on stylistic clues, manufacturing techniques, and the choice of materials characteristic of specific design movements.

Their survival in fine condition suggests they were treated as decorative desk furniture rather than utilitarian stationery supplies.
