Rectangular-shaped bread lame, using standard double edge razor blade and no extra hardware parts.
Be careful! Razor blades are sharp! Handle with care!
After using my original design for 5 (!) years, decided it was time to make a new model that deals with some of the usability annoyances with the older design.
- Uses a sliding mechanism to expose the blade, instead of having to fiddle with the lid and blade.
- Exposes only one corner, instead of the entire head.
- Unused blade edge is less exposed, for slightly more safety.
- Instead of a fancy compliant lock, I stuck with the retainer clip design.
Fully extended, there is ¾" blade exposed.
Fully collapsed, the dimensions are approx. 47mm x 29mm x 8mm.
Usage Notes
Assembly:
- Insert razor blade into slider.
- Grasping slider+blade (carefully!), insert fully into case.
- Use clip to retain slider.
Usage:
- Hold case by the sides, fingers away from the triangle!
- Remove clip; try not to lose it.
- Using slider tab, slide blade out.
- Use clip to retain slider in exposed position.
- This is optional; just squeezing the case is enough to prevent movement, but safety first!
Printing Instructions
As pictured: 0.4mm nozzle, 0.2mm layer height, PLA
- Print the 3 pieces; STLs should already be oriented for printing.
- Optionally mirror the slider and case; still unsure of the optimal handed-ness.
- Insert slider into case without a blade; make sure it slides freely!
- (Optional) Squeeze the clip-ends if it does not have enough clamping pressure for your liking.
- (Optional) Color in the triangle for extra visibility.
