File and rasp references differ in working-surface shape, profile and the configuration of one or both ends. Keep the instrument pattern separate from any claim about surface grade or cutting performance.
This category includes distinct hand-instrument patterns with different size and working-end conventions. An enquiry should identify each item individually rather than infer a complete procedure set from the category name.
Elevator and lever references should be compared through their working-end shape, width and curvature. Similar handle outlines can conceal differences in blade form or shank angle.
These references should be distinguished by blade cross-section, cutting-end shape and width. A flat chisel, a gouge and an osteotome should remain separate item descriptions even when their handles appear similar.
A scalpel handle number describes a pattern or fitting reference rather than a product stock code. Standard, long, round and angled handles can differ in both grip design and the compatible blade connection.
Probe and director references can differ in tip form, shaft flexibility, channel shape and complete length. Their shared slender appearance should not replace a precise description of the intended instrument pattern.
Thumb-forceps references can share a broad spring-handle shape while differing in terminal teeth, serrations and jaw width. Adson, Adson-Brown, DeBakey, Gerald, Bonney and Lane names should be followed by the required working-end specification.
Hemostat references differ in jaw length, serration extent, curvature and terminal teeth where applicable. A Mosquito, Kelly, Crile, Pean or Kocher pattern should be identified more precisely than a generic ring-handled clamp.
Periodontal instrument lists may include scalers, curettes and other named working-end patterns. These names should remain separate purchase descriptions rather than being grouped into a single generic hand-instrument line.
Orthopedic retractor lists may include broad blades, narrow blades, shaped tips and double-ended references. Named patterns can have multiple size options, so the working-end dimensions need to be stated explicitly.
