Picture













Q1: What type of blade does this OTF scalpel knife use?
A: This knife uses a #24 carbon steel scalpel blade, which is a standard size known for its exceptional sharpness and precision. This type of blade is commonly used in medical, crafting, and industrial applications where fine, accurate cuts are required. It is also compatible with #23 blades, etc.
Q2: Is the blade replaceable? How do I change it?
A: Yes, the blade is fully replaceable. It features a quick-change system that requires no tools. The knife comes with 10 spare #24 blades to keep you productive.
Q3: What is this knife designed for?
A: This precision scalpel knife is designed for fine, detailed cutting tasks, including:
Opening packages, envelopes, and mail
Cutting tape and removing labels
Leather crafting and cutting
Model making and hobby work
Precision trimming in arts and crafts
Outdoor survival and camping tasks
Q4: What materials are used in the construction?
A: The handle is made of aluminum alloy, making it exceptionally lightweight (only 35g) yet durable. The blade is made of carbon steel, chosen for its ability to take and hold a razor-sharp edge.
Q5: Is this knife suitable for everyday carry (EDC)?
A: Absolutely. Its ultra-lightweight design (35g) , compact size, and keychain hole make it perfect for EDC. It can be easily attached to your keychain, backpack, or belt loop, ensuring you always have a precise cutting tool at hand.
Q6: Do you offer customization options?
A: Yes. We support full OEM customization for bulk orders, including:
Custom colors (beyond standard black)
Logo imprinting (laser engraving or silk printing)
Custom packaging with your branding
Please contact our sales team to discuss your specific requirements.
Q7: How does this compare to a standard utility knife?
A: The key difference is precision and scale. This scalpel knife is designed for finer, more detailed work compared to a standard box cutter. It uses a thinner, sharper #24 blade and has a lighter, more maneuverable handle, making it ideal for tasks like crafting, leatherwork, and opening packages with precision.
Q8: Is the knife safe to carry and use?
A: Yes. The retractable OTF design allows the blade to be fully retracted into the handle when not in use, preventing accidental cuts. The OTF slide mechanism requires deliberate action to deploy the blade, adding a layer of safety. Always follow safe handling practices.
