Adélie Crossbar Locking Utility Knife with Pocket Hook! Fully Printable, No Screws, No Springs, No Glue

Introducing The Adélie Utility Knife

This is a fully functional 3D printable utility knife that takes standard Stanley style blades. Too broke to afford a Benchmade? Too cheap to spring for a CQC? Just print one of these, which is totally just about 5% as good! Probably!

Insofar as I am aware, this is the world's first “Axis” or crossbar locking folding knife that is also equipped with a “Wave” style pocket hook opening mechanism. Never mind a 3D printed one – This the only one, period. These two great pocket knife innovations are finally brought together. There may be imitators cropping up some time in the future, but this is the original.

Assemble and use at your own risk. Knives are sharp. Do I really have to tell you what the purpose of a knife is?

Features

• Completely 3D printable design requires the purchase of no screws or external hardware except the blade. No springs or glue required.

• Fully functional crossbar locking mechanism which both locks the blade carrier open and also detents it closed so it won't open in your pocket.

• Penguin Beak opening hook can be used to open the knife manually, or automatically snap it open when drawn from your pocket! See it in action:

Trust me, that never gets old.

• Reversible deep carry pocket clip for left or right handed users.
• Fully ambidextrous controls for both opening and closing. Lefty friendly design!
• Busing pivot operates freely, and even allows for performing the “Axis Flick” trick, just like a commercial Axis/crossbar knife!

Printing Tips

• Print in the strongest material your printer can manage. PLA works. PETG or ABS is better.
• Print all parts with their flat sides down against the print bed, except…
• Print the clip standing up on its edge with the point on the cone over the screw hole facing upwards.
• For best performance, print in black and white. Obviously.

Updates

Due to the continual treadmill of [papering over my screwups] innovation and improvement, the following updates have been made to these files as of 2024-07-14:

• Additional bushing sizes are provided with oversized inner diameters, in 0.1mm increments to compensate for your printers state of tune or settings.
• Closed position lockup ramp angle increased for a more positive detent.
• Text size on scales increased slightly for easier printing.
• Redesign of liners and crossbar to make it harder to break the flange off of the crossbar. Incompatible with old parts; redownload and reprint. All other parts remain compatible.

Assembly Instructions

Requires the following parts:

• 1x Upper and 1x Lower Liner
• 1x Upper and 1x Lower Scale
• 2x Screws
• 1x Crossbar
• 1x Blade Holder
• 1x Pivot Bushing in Your Desired Size
• 1x Clip (Optional)

Start with either liner. It doesn't matter which one; they are mirror images of each other.

Push the crossbar into its track in the liner. The spring prong in the liner must wind up behind it. It will be a close fit, but it will go in. If necessary, you can gently push the spring prong sideways out of the way.

Push the crossbar through its track on the other liner. The flat sides of the liners must face outwards, obviously. This will be a bit more of a fiddle than the first step, but the procedure is ultimately the same.

Put the bushing in its hole in the blade holder. I got carried away here and put the blade in ahead of time. You can install the blade now and live life on the edge, or if you're a wimp you can install it later.

Slot the blade carrier in between the liners. You may have to spread them apart slightly to get it to clear.

Slap the corresponding scale on one side.

Insert one screw in each hole and thread them through the scale and liner on that side only. Don't go all the way through yet. Press the scale against the liner so no gap is left between the liner and scale.

If you are going to use the clip, decide which side you want it on. It slots in a rectangular hole left in the tail end of the liners.

Put the other scale on, slipping it under the clip if necessary.

Finish threading in both screws so that both ends are flush with the surfaces of the scales.

Ensure that there are no gaps left between the scales and liners, and between the inner surfaces of the liners where they meet. If you are left with a gap, you didn't thread one of the screws in correctly.
