The blade a clinic specifies decides how much control it keeps over every incision it makes. This guide works through the geometry behind a 1.15mm sapphire hair transplant blade — width, thickness, entry angle and length — and explains why those four variables, rather than brand preference, determine whether a high density fue blade protocol behaves the way the surgical plan intended.
Dense packing changes what the blade has to do. When thousands of recipient sites are placed into a limited surface area, each incision stops being an isolated event: it becomes one of a sequence that must stay consistent in width, depth and angle from the first site to the last. A blade that widens, dulls or drifts mid-case forces the surgeon to compensate — and that compensation shows up as trauma the graft has to survive.
That is why blade geometry is treated by experienced teams as a governed variable rather than a personal preference. Width sets how much tissue the tip displaces. Thickness sets the cross-sectional squeeze applied at the incision edge. Length sets how much depth is available for the graft to sit in. Entry angle sets how the follicle is approached and seated. Change any one of them and the others stop behaving as planned.
This page is written for the people who specify the blade: surgeons, clinic technical directors and clinical trainers. Each module below isolates one governing variable, explains the mechanism it controls, and closes on the decision it forces — ending with the C-50 measured against all four.
Every mechanical insult at the incision is a survival risk carried by the graft. The product page states that this blade is designed to reduce follicular unit damage and support graft survival rates, with low-trauma blade technology intended to keep tissue damage minimal.
Trauma at the recipient site is described on the product page as minimised to surrounding tissue, with the stated aim of supporting accelerated patient recovery. Geometry — not force — is what keeps that boundary clean across a long case.
The product page states compatibility with high-density FUE blade protocols and integration into follicular extraction systems. Holding a density target means holding incision dimensions constant while site count rises.
Four numbers describe this blade family, and each one answers a different clinical question. The C-50 sets the reference values used throughout this page: 1.15 mm width, 0.25 mm thickness, 45° or 60° angle, and 4.5 mm, 5.0 mm or 5.5 mm length. Read them as a chain of decisions rather than a spec list.
Width is the primary determinant of incision calibre and therefore of how tightly a follicular unit is seated. A 1.15 mm width sits at the wider end of the sapphire FUE range, which suits protocols where larger multi-hair units are being placed. Narrower widths on the same platform exist for finer sites.
Thickness is measured front-to-back across the blade body, not across the cutting edge. A 0.25 mm body displaces far less tissue than a conventional thicker blade as it passes through the dermis, which is the mechanism behind reduced squeeze on the graft. This has its own module below.
Angle governs how the follicle is approached at entry; length governs how much depth is available once the tip is inside. The C-50 offers 45° and 60° angles and three lengths, so the same blade platform can serve shallow, high-root placement and deeper seating without changing instruments.
How 4.5 / 5.0 / 5.5 mm maps to how deep a graft can sit, and which option suits which protocol.
Read the depth module → Variable 2 · MechanismWhat happens at the incision boundary when the blade body is thin, and why thinness is not sharpness.
Read the thickness module → Variable 3 · EdgeEdge retention, sharpness decay and the cost-per-use trade-off between sapphire and steel edges.
Read the edge comparison →Blade length does not decide the depth of an incision; it decides how much depth is available. The tip can only reach as far as the blade extends, so a longer blade widens the range of placements a surgeon can make, while the actual depth is still set by how far the blade is inserted and where the insertion stop is held. Length, in other words, is a capability ceiling, not a depth setting.
| Blade length | Depth available at the tip | Protocol note |
|---|---|---|
| 4.5 mm | Up to 4.5 mm | Shallow, tight recipient sites. Suited to thin scalp and high-root placement where the surgeon wants minimal blade body below the surface and the firmest possible depth stop. |
| 5.0 mm | Up to 5.0 mm | The general-purpose option and the most common starting point for dense packing on average scalp thickness — enough reach for standard seating without excess blade below the surface. |
| 5.5 mm | Up to 5.5 mm | Deeper seating for thicker scalp or for grafts placed lower in the dermis. Greater reach means more blade below the surface, so depth control depends more heavily on the surgeon's insertion stop. |
The C-50 ships with 4.5 mm, 5.0 mm and 5.5 mm lengths on the same platform. Final incision depth is a surgical decision made at the chair, not a specification — confirm your depth protocol with your clinical lead.
“Blade length does not set the depth of an incision. It sets how much depth the tip can reach — the insertion stop decides everything after that.”
As a blade passes through the dermis, it does not only cut — it also displaces. The body of the blade pushes tissue aside to make room for itself, and that displaced tissue presses back on everything nearby, including the graft already sitting in an adjacent site. That lateral pressure is what clinicians describe as squeeze.
The C-50 is built at 0.25 mm thickness. A thin body means less tissue has to move out of the way for the blade to advance, which reduces the lateral load transmitted to neighbouring grafts during dense packing. The product page describes this family as low-trauma hair transplant blade technology, stated to minimise tissue damage to surrounding tissue — the tissue-squeeze mechanism is the physical reason that claim exists.
On a high-density protocol the effect compounds. Every additional site placed close to the last one increases the chance that squeeze from one incision disturbs a graft in another. Reducing the displacement per pass is how a protocol protects a density target it has already committed to.
Thickness and sharpness are different properties with different jobs. Thickness is a cross-sectional gauge: it decides how much tissue the blade displaces as it travels. Sharpness is an edge property: it decides how cleanly the tissue separates at the point of contact. A thin blade with a rounded edge still tears; a sharp blade with a thick body still squeezes. High-density work depends on both being controlled at once — which is why the C-50 pairs a 0.25 mm body with a sapphire cutting edge rather than optimising either one alone.
The sharpest blade in the world is only as good as its condition at the five-hundredth site. Sapphire and steel fail differently under repeated use, and that difference is what drives the cost-per-use argument — not the sticker price of a single blade.
| Comparison criterion | Sapphire edge (C-50) | Steel edge |
|---|---|---|
| Edge material | High-hardness sapphire, stated on the product page for wear resistance and sharpness retention. | Conventional surgical steel — softer at the edge, so the cutting geometry yields sooner. |
| Sharpness decay pattern | A hard crystalline edge wears by gradual, relatively uniform rounding rather than local deformation. | A softer edge tends to roll or fold locally, producing a sudden change in cutting behaviour within a case. |
| Behaviour over multiple uses | The product page states durability over multiple uses with selectable lengths and angles for modular adaptability. | Typically treated as a consumable, replaced frequently to hold a working edge. |
| Handling and control | Ergonomic handle options are stated to enhance surgeon control during scalp microblade operations; handle available in blue or silver. | Handle design varies by supplier and is not tied to edge material. |
| Sterilisation and repackaging | Packaging is stated to withstand high-temperature sterilisation without deformation; each blade ships with a dust cover. | Generally tolerant, but re-sterilisation handling varies by manufacturer and packaging. |
| Cost per use | Higher unit cost, offset by a longer working edge and reduced mid-case instrument changes. | Lower unit cost, offset by more frequent replacement across high site counts. |

With an ultra-sharp design, this custom sapphire surgical blade supports low trauma extraction. Procured from a leading sapphire surgical blade factory.
View productmodel c-50, part number ptc501150001: 1.15 mm width, 0.25 mm thickness, selectable 45° and 60° angles, and 4.5 mm, 5.0 mm or 5.5 mm blade lengths, made from high-hardness sapphire. the blade itself is transparent, with handle options in blue or silver. note that the product url reads “115mm” — the blade width is 1.15 mm.
blade length sets how much incision depth is available, so 4.5 mm suits shallow, high-root placement in thin scalp, 5.0 mm is the general-purpose choice for dense packing, and 5.5 mm gives deeper reach for thicker scalp or grafts seated lower. the final depth is set by how far the surgeon inserts the blade, so confirm the depth protocol with your clinical lead.
thickness and sharpness control different things. thickness is the cross-sectional gauge that determines how much tissue the blade body displaces as it passes through the dermis, which is what creates lateral squeeze on neighbouring grafts. sharpness is an edge property that determines how cleanly tissue separates at contact. a 0.25 mm body reduces the displacement per pass, which is the mechanism behind the stated low-trauma design.
the product page states compatibility with high-density fue blade protocols and integration into follicular extraction systems, and states that the blade is designed to reduce follicular unit damage and support graft survival rates. the combination of a 1.15 mm width, 0.25 mm thickness and selectable lengths and angles is what makes that density work practical. confirm suitability against your own protocol before ordering.
the blade is transparent with handle options in blue or silver. each blade is supplied with a dust cover in a high-temperature resistant plastic case available in three styles, with sturdy cardboard boxes for logistics, and the packaging is stated to withstand high-temperature sterilisation without deformation. custom size fue blades are offered, and bulk or oem orders can be arranged through a quote request.
