Description

This tactical folding knife features a locking button and rugged exterior design. It prints in about 1.5 hours, uses only 18g of filament, and requires no hardware or glue for assembly—just one blade!

Alternative version available: using M3x6mm screw and nut

Tested with Stanley brand blades. Compatible with slightly smaller blades, but larger blades CANNOT be used.

Printing: Needs minimal supports that peel off easily. Works perfectly with PETG, PLA (including silk/basic colors). Tested on H2D printer.

New Version Update: need one M3x6mm screw and M3 nut.

Assembly Tutorial:

1.See all parts.

2.Insert the red locking structure into the blue handle's groove. Tighten the White round button on the opposite side to secure it.

3.Install the blade holder onto the pivot point—make sure orientation is correct!

4.Align both grip halves and press firmly on the snap at the handle's end until you hear a "click".

5.Secure the grips with the black ring part..

6. Insert the utility cutting blade into the holder. Done!

The strength of 3D-printed knives cannot be guaranteed and they are suitable only for light-duty tasks, such as cutting paper or opening Amazon packages. Unless otherwise specified, all of my knife designs are intended for light-duty use only.

Another very nice knife design that printed great. my only complaint/suggestion to other users is not to use silk PLA. with Silk PLA the small piece that stops the blade when fully open snapped off with minimal force while trying to lock the knife open. But even without that small stop the blade locks up decently for a 3D printed knife.

Awesome design as always. Love the flipping and locking action on this one even more, keep up the great work!

where do you find the cool designed razor blades

@faluethi108

I want to know that too xD i couldn't find anything on Google

@cbojorges

I think they are utility knife blades.

@user_1979361542

Safety knife blades Most are standard sizes but occasionally products have different dimensions

I’m using it as a fidget 😁

@user_3108417831

you should add a fake blade to make it more "real"

Fantastic design, and very useful tool to have. Unfortunately, the blade is still rocking around 2mm vertically. I hope this will be further improved in V2.

@user_316897565

For me, this is the most practical portable knife to assemble without any tools Yes, there is a little play, and I will further enhance the safety aspects I will use it as an everyday carry item I will not cut meat with it Thank you

Version Update: Blade positioning assembly using one M3x6mm screw and M3 nut.

@user_316897565

I simply desired a knife system without external parts I find it incredibly practical in any case

the profile of this one is my absolute favourite. I added a pin on the side to stop the blade from going too far under the handle and getting stuck

@Champion

did you post the print profile for the version you made ?

perfect 👍🏻,,,, please need more support for (check the second picture because broken) ✌🏻🌹

@lancezhc

This spot is built vertically on the print bed, so you can't add supports—and honestly, it's completely unnecessary anyway. Any damage here probably comes from pressure when opening the blade, but don't sweat it if this part breaks or goes missing. Because the parts that actually take the force are the sides.
