The SINSEUNG L202 18 mm utility blade is a cutting consumable made from SK2 high-carbon steel and intended for
industrial manufacturing, precision handwork and general office tasks. Its design combines a standard 18 mm
format with an eight-segment snap-off structure and a 60-degree tip angle, according to product
specifications.
Core specifications and physical characteristics
The L202 is manufactured from SK2 high-carbon steel, a material selected for hardness and edge retention. The
specification states that the steel resists wear during frequent use, supporting the blade’s intended role as a
durable cutting consumable.
The blade measures 18 mm in width and 109 mm in length. It uses an eight-segment snap-off design, allowing the
front section to be removed when dulled. Packaging is specified as 10 blades per tube, 10 tubes per box and 36
boxes per carton.

Performance characteristics
Geometric precision and cutting behavior
The 60-degree tip angle is intended to provide a smooth and accurate cutting path. For materials including thick
cardboard, leather, industrial rubber and plastics, the angle is designed to reduce resistance and support a
consistent cut surface.
Segmented maintenance and cost control
The eight-segment snap-off structure is central to the blade’s maintenance model. When the tip becomes worn,
the user can break off the old segment to expose a new cutting edge, extending the service period of each blade
without replacing the entire unit.
Compatibility and operational use
The blade’s symmetrical structure is intended to accommodate both left- and right-handed users. This design
consideration supports use in industrial assembly lines and workshop environments where consistent handling and
compatibility are required.
Applications and operational considerations
The L202 is positioned for cutting tasks across industrial production, precision manual work and routine office
use. Its dimensions follow the standard 18 mm utility blade format, but frame compatibility may vary by
manufacturer.
Because internal slot tolerances differ among blade holders, users should confirm that the frame’s locking
mechanism is compatible with the blade thickness. The product specification identifies the L202 as a standard
18 mm blade with an eight-segment structure and a 60-degree tip angle.
Frequently Asked Questions
What is the difference between SK2 high-carbon steel and ordinary carbon steel in blade performance?
SK2 is a high-carbon tool steel with higher quenching hardness and wear resistance. In cutting use, this
means the edge is less likely to roll when processing hard materials such as thick leather or plastics,
helping it remain sharp for longer and reducing replacement frequency.
How can users tell when an 18 mm blade should be snapped to a new segment?
When cutting resistance increases noticeably or the cut edge shows burrs or tearing, the blade edge has
become dull. At that point, the front dulled segment should be broken off in a safe manner to expose the
next sharp cutting edge.
Does this blade fit all 18 mm utility knife frames?
The L202 uses standard 18 mm dimensions, but internal slot tolerances may differ among frame brands. Users
should confirm that the frame’s anti-slip locking mechanism is compatible with the blade thickness before
use.
