Product Information
Full details
The Hultafors SFRP 18A Auto-Lock Snap-Off Knife is a high-durability tool designed for professionals who require precision and reliability during intensive construction tasks such as cutting plasterboard, insulation, and wood. Its key benefit is a reinforced steel-core construction paired with a tapered tip for superior blade visibility, though users should note that the auto-lock mechanism requires intentional thumb engagement to adjust blade depth.

FAQs
What size blades does this knife use?
This knife uses standard 18mm wide snap-off replacement blades.
How many spare blades can I carry in the handle?
The internal storage compartment can hold up to three spare 18mm blades.
Can the tail fin be used as a screwdriver?
No, the tail fin is designed for tucking carpets and opening cans; using it as a screwdriver may damage the tool housing.
Is the handle resistant to chemicals?
The PC-plastic housing is highly durable and resistant to typical job-site environments, but it should be cleaned promptly if exposed to harsh solvents.
Does the blade come included?
Yes, the knife comes supplied with a professional-grade 18mm snap-off blade.
Troubleshooting
Blade segment is difficult to advance
Check the rail for dust or plasterboard residue buildup; clear the track and apply a light silicone lubricant.
Auto-lock slips during heavy cutting
Ensure the lock mechanism is fully engaged and check the rail channel for obstructions that might prevent the lock from seating properly.
Pros and Cons
Pros
- Extremely durable construction with reinforced steel core
- Superior blade stability due to the 1mm metal rail
- Integrated spare blade storage for increased productivity
- Ergonomic handle reduces hand strain
- Versatile multi-tool tail fin for carpet tucking and opening cans
Cons

Setup, Compatibility & Care
To begin using the Hultafors SFRP 18A, ensure the blade is correctly seated in the rail mechanism before extending. The knife is compatible with all standard 18mm snap-off blades, though using genuine Hultafors replacement blades is recommended for optimal fit.
Maintenance Tips:
- Cleaning: Periodically remove debris from the blade rail using compressed air or a soft brush to prevent the sliding mechanism from jamming.
- Lubrication: A light application of silicone-based lubricant inside the rail can keep the auto-lock mechanism moving smoothly.
- Blade Changes: Always snap off dull segments using the integrated snapper tool on the base or a pair of pliers to ensure a clean break point.
