In the national-level digital preservation project for intangible cultural heritage,

 custom tungsten steel cutting blades have been deployed for high-precision replication of Ming and Qing dynasty paper-cut art and shadow puppetry patterns.

Their cutting edges are precision-finished using five-axis grinding machines, enabling stable cutting of 0.05mm-thick rice paper without edge chipping,

 flawlessly reproducing traditional techniques such as "saw-tooth patterns" and "crescent patterns."

Moreover, the blades are integrated with a force feedback system, preventing broken lines caused by uneven manual pressure.

 As heritage inheritors remarked, "Only when traditional craftsmanship is equipped with modern tools can culture truly remain alive."
