Sapphire Blade Size Chart: Widths in mm and What Each Cuts

Sapphire recipient-site blades are supplied by width, typically from about 1.0 mm to 2.0 mm in 0.1 mm steps, with some product lines extending below 1.0 mm for ultra-fine hairline work. Width is the primary selection variable: it sets the incision length, which must match the caliber of the graft going into it — narrow widths for single-hair grafts at the hairline, wider ones for two- and three-hair units behind it. The chart below maps each width band to its typical incision use and graft pairing. Widths, tip angles and even the measuring convention vary between manufacturers, and blades fit brand-specific holders, so confirm dimensions and holder compatibility against the supplier's datasheet before ordering.

How widths map to a case

A recipient area is not cut with one blade. A typical plan runs from the finest width at the frontal hairline — where single-hair grafts and irregular, soft transitions demand the smallest possible incisions — through intermediate widths in the transition and mid-scalp zones, to the widest stocked size where three- and four-hair units carry density. Surgeons therefore think in sets, not single blades: a hairline width, one or two mid widths, and a multi-hair width, switched as the plan moves back across the scalp. The blade should open an incision the graft fills snugly — too narrow risks trauma on insertion, too wide costs anchorage and density precision. The same graft-to-instrument matching logic governs the extraction side; the sapphire vs steel comparison covers why fixed-width sapphire sets behave differently from custom-cut steel here.

Size chart

Nominal widths and pairings below reflect common practice across major product lines; individual manufacturers step and label differently.

Width (mm)	Typical incision use	Typical graft pairing	Notes
1.0	Frontal hairline edge, temple points	Fine single-hair grafts	Finest routinely stocked size; some lines offer 0.8–0.9 mm below it
1.1	Hairline zone	Single-hair grafts	Common hairline default in medium-caliber hair
1.2	Hairline and transition zone	Singles in coarse hair, fine two-hair units	Frequent crossover size between zones
1.3	Transition zone	Two-hair units	—
1.4	Transition and mid-scalp	Two-hair units	Often the most-consumed width in a mixed case
1.5	Mid-scalp	Two- and small three-hair units	Upper end of many standard sets
1.6	Mid-scalp and crown	Three-hair units	—
1.7	Mid-scalp and crown	Three-hair units, coarse doubles	—
1.8	Density zones, crown	Three- and four-hair units	Stocked selectively by case mix
1.9	Density zones	Large multi-hair units	Less commonly stocked
2.0	Coarse multi-hair work, occasional beard-to-scalp grafts	Largest follicular units	Top of most catalogs; confirm availability

Widths alone do not fully specify a blade: product lines also vary tip angle, which changes how the blade enters tissue and how depth is controlled at a given width. The angle families and how to choose among them are covered in the sapphire blade angle guide.

Ordering a mixed-width set

Consumption is not uniform across widths. In a typical mixed case the middle sizes (roughly 1.2–1.5 mm) do most of the work, hairline widths see moderate use, and the widest sizes are consumed only where multi-hair density is planned — so a flat "ten of each" order mismatches real usage from day one. A better first order weights the middle of your range, adds one width below and above what you expect to need, and lets two or three cases of actual consumption set the reorder ratio. Because sapphire blades are individually mounted and chip rather than dull, count spares per width into the session math as well.

Two compatibility caveats before any volume order. First, holders: blades mount in dedicated handles, and neither blade shank nor holder clamp geometry is standardized across brands — a blade that sits loosely in a foreign holder wastes its edge precision. Second, measuring convention: confirm whether the stated width is the cutting-edge width or a shank dimension, and ask for tolerance figures. Both questions belong in writing with the supplier; the commercial side of that conversation is covered in the wholesale sapphire blades guide, and the wider material context in the sapphire blades hub.

Frequently asked questions

What sizes do sapphire blades come in?

Most lines run from about 1.0 mm to 2.0 mm in 0.1 mm steps, with some manufacturers offering 0.8–0.9 mm for ultra-fine hairline work. Narrow widths serve single-hair hairline grafts, mid widths two-hair units, and the widest sizes multi-hair units in density zones.

How do surgeons pick a blade width during a case?

By matching incision length to graft caliber zone by zone: the finest width at the hairline for singles, intermediate widths for two-hair units in the transition and mid-scalp, wider blades where three- and four-hair units carry density. A case typically consumes a set of widths, not one size.

How many blade widths should a clinic stock?

Most teams hold four to six widths: one or two hairline sizes, two or three mid sizes, and one multi-hair size, with spares per width since sapphire chips rather than dulls. Weight orders toward the middle widths, which are consumed fastest in mixed cases, then let real usage set reorder ratios.

Do sapphire blades from one brand fit another brand's holder?

Assume not. Shank and clamp geometry are not standardized, and a blade that seats imperfectly undermines the edge precision you paid for. Verify fit of sample blades in your actual holders — across a box, not one unit — and get cross-compatibility confirmed by the supplier in writing.

Is width the only specification that matters?

No. Tip angle changes insertion feel and depth control at any given width, and manufacturers differ in how they measure and tolerance the stated width. Specify width, angle, and the measuring convention together, and confirm all three against the datasheet rather than the catalog headline.
