Scissors are where surgery drawers quietly go wrong: five assorted pairs, none sharp, none assigned a job. The fix is not more scissors — it is two well-chosen pairs with defined roles, kept sharp and processed properly.
1. The iris pattern
Short, fine, pointed blades on a light body — iris scissors came from ophthalmology and stayed for every task needing controlled cuts near tissue: trimming cord, sutures, membrane work. Our iris dressing scissors are the surgical-steel version with edges ground, not stamped.
2. Fine pair, utility pair
The two-pair strategy: an iris pair that only ever touches fine work, and a utility pair for matrix bands, dam sheet and packaging. The moment a fine pair cuts a matrix band it becomes the utility pair — metal kills tissue edges in one appointment. Label them; the discipline mirrors the fixed-contents rule from cassette organisation.
3. Reading a good blade
Held to the light, the blades should meet in a smooth kiss from pivot to tip with no gaps; the cut should feel progressive, not crunchy. That comes from the grind and the pivot — the same joint engineering covered in our box-joint explainer applies to the screw joint here.
4. Edge care
Scissors tolerate ultrasonic and autoclave cycles happily (autoclave care) but hate being dumped loose in a drawer, tips-first. Rail them in a cassette or sleeve the tips. Professional re-grinding is worthwhile exactly once or twice; after that, edge geometry is gone and replacement wins — the lifespan calculus again.
5. Beyond the surgery
Lab-side, the same logic scales up: the plaster shears in our lab & modelling range do for casts what iris scissors do for cord. Siblings on the tray: dressing tweezers. Every pair is CE-marked Class I — chain of provenance on the compliance page.
