Description
Forty knives, one versatile cutter. The Proxxon knife set for the MICRO-Sonic Cutter MSC provides 40 cutting knives plus 2 collets in a storage box — covering the full range of materials the MSC is designed to cut cleanly and precisely. The ultrasonic cutting action of the MSC means these knives slice rather than saw, producing clean edges without fraying, tearing, or heat damage on sensitive materials.

Knives vs. Other MSC Accessories
The MICRO-Sonic Cutter MSC accepts three types of accessories — each suited to different cutting tasks:
- Knives (No. 27302) — this set: For slicing cuts in plastics, composites, foils, leather, and soft materials. Clean, drag-free cutting action.
- Saw blades: For materials that require a sawing action — harder or thicker stock where a knife edge would deflect.
- Scrapers: For removing adhesive residue, labels, and surface coatings without damaging the substrate.
Frequently Asked Questions
Is the MSC tool included?
No — this is an accessory set for the Proxxon MICRO-Sonic Cutter MSC, sold separately.
Why use ultrasonic knives instead of a regular blade?
The ultrasonic vibration of the MSC causes the knife to slice through material with minimal drag and no heat buildup — producing cleaner edges on sensitive materials like CFRP, resin prints, and leather than a static blade or rotary tool would.
Are the collets included?
Yes — 2 collets are included in the set along with the 40 knives and storage box.
