Folding OTF Scalpel Manufacturer - Custom Surgical Utility Knives
The MS41 OTF Scalpel is a compact out-the-front cutting instrument built for industrial users, lab technicians, warehouse staff, and EDC buyers. Its die-cast zinc alloy handle houses a dual-action OTF slide that deploys and retracts a replaceable #24 carbon steel blade with one hand. It delivers surgical-level sharpness for cardboard, film, tape, leather, rubber, and craft materials—then snaps back into a pocket-safe housing. As a direct Yangjiang, China manufacturer, we supply bulk wholesale, OEM logo engraving, and custom anodized colors with stable monthly capacity.

FAQ
A: Yes. The MS41 uses a universal #24 carbon steel scalpel blade that is fully interchangeable with standard industrial #24 refills. Blade swap is tool-free—retract the actuator, slide the old blade out of the front channel, and insert a new one. Spare blades are included in each unit, and bulk refill packs are available for wholesale buyers.
A: Absolutely. The handle is made from die-cast zinc alloy, which offers high rigidity, impact resistance, and dimensional stability at a lower cost than aluminum—ideal for high-volume industrial distribution. The OTF channel keeps the blade aligned under lateral pressure, making it suitable for carton opening, film cutting, leather crafting, and light workshop tasks.
A: OTF (Out-The-Front) means the blade travels linearly from the nose of the handle. The MS41 uses a dual-action slide—push forward to deploy, pull back to retract, all one-handed. This eliminates the pivot wear of folding knives, reduces accidental finger contact during deployment, and keeps the tool pocket-safe when closed.
A: Primary B2B buyers include industrial suppliers, hardware wholesalers, lab equipment distributors, leather-craft brands, and promotional EDC companies. Because the #24 blade is a globally recognized standard, procurement managers favor it for training kits, workstation dispensers, and private-label utility lines.
