Introduction: A 1. 15 mm sapphire FUE blade fits high-density recipient-site work when planned graft caliber and inter-site spacing fall between what 1. 0 mm and 1. 2 mm openings provide.
The C-50 blade from JM Surgicals adds length and angle options to a fixed 1. 15 mm cutting width, so a hair restoration surgeon can evaluate one standard product across different scalp depths, entry directions, and graft diameters before deciding whether it belongs in routine supply. Recipient-site evaluation for this width should center on graft diameter, spacing, tissue support, incision depth, and entry behavior rather than on the assumption that a narrower blade is always safer.
High-density FUE shifts the surgical problem from extraction to recipient-site geometry. When a surgeon places a high number of grafts in a small area, every incision removes or displaces a small amount of dermal tissue, so the distance between openings becomes a physical constraint. If adjacent sites are too wide or too close, the remaining tissue may not give each graft enough support while it settles. The blade therefore has to create a clean channel along the planned hair direction and leave enough intact dermis between openings to keep the recipient bed stable. The cutting width defines the cross-section of that channel. A 1. 0 mm opening can feel tight when the planned graft is a thick multi-hair follicular unit; seating the graft may require more pressure than the surgeon wants. A 1. 2 mm opening offers easier entry but removes more supporting tissue, which can destabilize neighboring sites in a dense session. The 1. 15 mm width is a standard-position middle option: it suits cases where graft caliber and spacing sit between those two extremes. A hand-polished sapphire edge and transparent blade body help the surgeon see the blade orientation and feel whether the slit is reproducible across many openings. What the recipient plan must establish is whether this middle width matches the graft caliber without excess force and without consuming more tissue than the density plan allows.
The C-50 variant PTC501150001 combines a 1. 15 mm blade width with a 0. 25 mm blade thickness, available in 4. 5 mm, 5. 0 mm, and 5. 5 mm lengths and in 45-degree and 60-degree cutting angles. The cutting edge is hand-polished sapphire, the blade body is transparent, and the blade can be fitted to a blue or silver handle. Each blade comes with an individual dust cap and a heat-resistant plastic case. In the recipient bed, width determines the size of the slit, length determines the useful cutting depth, and angle determines how the edge enters the skin. These three variables work together, not independently.
Incision depth in FUE recipient work is not a fixed number. Scalp thickness varies by zone, and the surgeon may need a shallow slit for a fine graft or a deeper path for a graft that should rest lower in the dermis. A 4. 5 mm length suits a shallower recipient bed where the surgeon wants less blade exposure. A 5. 0 mm length is a common middle choice for standard-depth incisions. A 5. 5 mm length gives additional reach when the scalp is thicker or firmer, or when a longer blade helps the surgeon maintain a consistent hand position through an angled entry. Graft survival depends on the full clinical plan; the purpose of length selection is to match the incision path to the planned resting depth without requiring excessive force or creating a deeper cut than intended.
The cutting angle changes how the blade tip transfers force at the start of the incision. A 45-degree edge presents a more acute contact surface, which may feel smoother when the blade enters at a shallow angle. A 60-degree edge meets the tissue more directly, giving a more pronounced tactile sense of entry when the planned recipient direction is steeper. Both edges are hand-polished sapphire, so the difference is not sharpness but the geometry of force transfer and the resulting wound-edge shape. Surgeons who favor shallow angled incisions for natural hair direction may prefer the 45-degree option; those who work with steeper recipient incisions may find the 60-degree option easier to control. The standard 1. 15 mm product makes both available so the surgical team can compare them on representative cases before committing to a length and angle combination.
The strongest fit for the 1. 15 mm blade is a session in which graft caliber falls between standard width categories. When a planned 1. 0 mm site is tight and graft seating requires more pressure than desired, while a 1. 2 mm site is wider than the tissue needs, the 1. 15 mm channel provides an intermediate opening. This situation often occurs in high-density cases with mixed follicular units: some sites receive fine single-hair grafts, while others receive thicker multi-hair units that must still be placed close together. The 1. 15 mm blade reduces seating force for those thicker grafts while preserving an intact column of tissue between adjacent openings. Planned density and incision direction are equally important. Dense recipient work requires sites to follow the direction of existing hair so that the final result looks natural and the local blood supply is preserved. The blade must track that path cleanly rather than displace tissue sideways. For the middle portion of a high-density case, where spacing is tight but the grafts are not uniformly fine, a 1. 15 mm slit gives the surgeon a useful balance between easy graft entry and tissue conservation. The blade is less likely to be the right starting point for very fine single-follicle hairline work, where a narrower opening may be preferable, or for low-density placement of coarse multi-hair grafts, where a wider opening may ease seating. The final decision should be based on the planned graft diameters and recipient spacing for each case. The last check belongs in the operating room, not only on a specification sheet. A product table can confirm width, thickness, length, angle, and material, but tactile fit during rapid, repeated recipient-site creation must be checked on a particular patient. The procurement step should therefore begin with a sample lot: request the C-50 1. 15 mm blade in the length and angle planned for routine work, and use it on cases that reflect the clinic's usual density, graft caliber, and incision direction. Compare entry resistance, graft seating pressure, and the stability of adjacent openings. During the inquiry, confirm handle inclusion, sterile state, and packaging details for the exact variant before stocking.
The 1. 15 mm C-50 from JM Surgicals is a standard-geometry option for high-density FUE sessions that require more room than a 1. 0 mm opening but less tissue loss than a 1. 2 mm opening. The product's 4. 5 mm, 5. 0 mm, and 5. 5 mm lengths, combined with 45-degree and 60-degree cutting angles, let one fixed width adapt to planned depth and entry behavior. Sapphire material and blade geometry provide mechanical conditions for clean incisions; surgical outcome also depends on graft handling, patient tissue, and the full operative plan. The practical route to routine use is a sample evaluation in the surgeon's own hands, followed by confirmation of handle, sterilization, and packaging terms with JM Surgicals.
A：The 1. 15 mm width defines the size of the recipient-site opening. In high-density FUE, it is most useful when a 1. 0 mm site feels too tight for the graft and a 1. 2 mm site removes more tissue than the spacing allows. This middle width supports graft seating with less pressure while preserving intact tissue between adjacent sites.
A：Blade length controls the useful depth of the cutting path: a 4. 5 mm length fits shallower recipient beds, a 5. 0 mm length suits standard-depth work, and a 5. 5 mm length provides additional reach for deeper or firmer scalp tissue. Blade angle controls entry behavior: a 45-degree edge presents a more acute contact surface, while a 60-degree edge meets tissue more directly. The surgeon chooses the combination based on planned depth, incision direction, and tactile preference.
A：Yes. A clinic can request the C-50 1. 15 mm blade as a small evaluation lot through the JM Surgicals inquiry process. Specify the PTC501150001 variant, preferred length and angle, and describe the graft caliber and density scenario planned for testing. Before placing the trial order, confirm handle inclusion, sterile state, packaging details, and current supply terms for the exact variant.
