WEDO AUTO-LOAD Profi Cutter 18 mm — Six Blades in the Handle, Loaded Without Tools
6 blades in the magazine18 mm snap-off, SK5 steelAll-metal blade carrierBreak-off tool included
The WEDO AUTO-LOAD Profi Cutter 78 418 is an 18 mm snap-off knife that carries six SK5 steel blades inside its own handle and loads the next one without tools, made for warehouses, fulfilment benches, carpet fitters, insulation installers and anyone who cuts cardboard and packaging in volume.
Changing a blade takes seconds: push the slider forward, lift out the remains of the spent blade, draw the slider back and forward again — the magazine feeds a fresh blade into the carrier. A rigid all-metal blade carrier keeps the long 18 mm blade from flexing at full extension, the ratchet advance with auto-stop holds the cutting depth under load, and a break-off tool is supplied on the card for snapping off blunt segments. The cutter measures 170 x 20 x 45 mm and weighs 150 g.
Before you order: This is a professional snap-off cutter, not a safety cutter: the blade does not retract automatically — retract it manually with the slider before putting the knife down. It takes standard 18 mm snap-off blades; trapezoid blades from WEDO Safety Cutters do not fit.
What's in the Box
- 1 x WEDO AUTO-LOAD Profi Cutter 18 mm, black / red (article 78 418)
- 6 x 18 mm SK5 snap-off blades in the auto-load magazine
- 1 x break-off tool (on the blister card)
What It Means in Practice
- Six blades on board means a full day of heavy cutting without opening a blade box.
- Tool-free reload — no screwdriver, no dismantling and no loose blades on the bench.
- The metal carrier keeps deep cuts straight in double-wall cardboard, carpet and insulation.
- Snap off blunt segments cleanly with the supplied break-off tool for a sharp tip every time.
What Will Not Work
- No automatic blade retraction — not suitable where workplace rules require a self-retracting safety cutter (choose WEDO Safety Cutter 78 805 or 78 808).
- WEDO publishes no TÜV/GS safety certification for this model.
- Does not take 9 mm blades — the 9 mm sibling is the 78 409 with five blades.
- Not for trapezoid utility blades.

Frequently Asked Questions
How does the blade change work?
Push the slider forward, remove the spent blade, then draw the slider back and forward again — the next blade is fed from the magazine. No tools needed.
Does the blade retract by itself?
No. The ratchet holds it where you set it; retract it manually. For automatic retraction choose a WEDO Safety Cutter such as the 78 805 or the aluminium 78 808.
18 mm or 9 mm — which do I need?
This is the 18 mm version (six blades) for cardboard, carpet, insulation and deep cuts. The 9 mm 78 409 (five blades) suits paper, film and detail work.
Singular Expert Insight · Buyer's Guide
The AUTO-LOAD earns its place wherever blade changes are the bottleneck — fulfilment benches, carpet fitting, insulation work — because a fresh edge is seconds away and the metal carrier keeps the 18 mm blade accurate. If your workplace requires self-retracting or certified safety cutters, this is not the tool. More cutters and desk tools in our
stationery range.
✓ Buy it if you cut in volume, change blades often and want six blades on board with a rigid metal carrier.
✕ Skip it if you need a certified safety cutter with an automatically retracting blade.
→ Also consider WEDO Safety Cutter STANDARD 78 805 or ALU Basic 78 808 for self-retracting blades.
