We've been having a good old time with this over on the Pocket Knife community, but I figure there's probably a lot of crossover with this crowd as well.

I'm sure you've seen various clever little one piece utility knife blade holders on Thingiverse and so forth, and while they're quite functional I don't think they're nearly as overwrought or silly enough, nor require quite enough components.

Rather than repeat my entire post from there over here, I'll leave you with these:

How does the blade stay secured? Years of retail has made me respect and fear bare razorblades

[–] [email protected] 6 points 11 months ago (1 children)

Maybe it’s a feature, it doubles as an improvised shuriken thrower.

The design is an interesting idea, but having suffered a few crappy box cutters I wouldn’t trust a blade with a friction fit.

It could only possibly be better if it had tits and were on fire.

Two pins go through the notches in it. It's not going anywhere.

That green one is my initial prototype and I've been pretty much continuously fidgeting with it at my desk since I printed it maybe two weeks ago. I have flipped it open and shut probably a couple of thousand times by now -- no exaggeration -- and the blade hasn't budged.

[–] [email protected] 2 points 11 months ago* (last edited 11 months ago) (1 children)

Is there like a lip or ridge on the top too that prevents the blade from flying backwards while flipping? I see it on the bottom of the blade, but can't tell if the top is also secured that way

[–] [email protected] 8 points 11 months ago

It rides in a track that encloses the top and bottom edges by a couple of mm.

The rear has an end stop, also. It can't fly in any direction, and the only way it's going any time soon is out the front if you press down the flexture that has the locking pins on it.

[–] [email protected] 3 points 11 months ago

From what it looks like you can slide it in and lock it with these two pins on top. Not sure how safe that is but considering we're talking about a makeshift balisong, safety can't be your main concern

[–] [email protected] 21 points 11 months ago

Oh, that's silly as hell, I love it.

[–] [email protected] 18 points 11 months ago

Hey, maybe were on the same watchlist!

[–] [email protected] 13 points 11 months ago (1 children)

Holy shit I cannot be the only one to think flipping one with a razorblade is a bad idea. Like, I've cut myself with my balisong and I keep it pretty sharp, I can't imagine how badly I'd cut myself with a balisong that's literally razor sharp.

[–] [email protected] 5 points 11 months ago* (last edited 11 months ago)

Just git gud!

Actually, just flipping around with this it's pretty tough to cut yourself. Obviously the safe side won't cut you, but the blade holder makes a signifigant length of the bite side blunt as well. The edge is only exposed for the last inch and some change, and you mess up the blunt heel section will just bonk harmlessly against your finger. You have to be really choked up on the handle for it to get you.

I think this is actually safer than a traditional balisong (being a DIY contraption made out of whatever bullshit we have lying around notwithstanding) which would have the entire length of one side sharpened.

If you’re gonna print a weapon, a balisong is the right choice. You were gonna hurt yourself with it anyway!

[–] [email protected] 8 points 11 months ago (1 children)

Sure, but this is not even remotely my first rodeo with the ol' flippy-spinny-do.

I'm a veritable expert by this point; I ought to put it on my résumé.

"Idontneedanotherhobby. Idontneedanotherhobby."

I'm at least making this razor balisong

[–] [email protected] 1 points 11 months ago

14 year old me can confirm. Backseat playing with it on the way to red lobster and when the interior car lights turned on my hands were red lol. I thought it was sweat lol

[–] [email protected] 7 points 11 months ago (1 children)

Can you make a version that works with Stanley 11-041 blades?

[–] [email protected] 6 points 11 months ago

I don't see why not, but I'd need one to measure. It could be as simple as making a new business end for the blade holder.

[–] [email protected] 6 points 11 months ago (1 children)

You should throw this up on printables and at least get some free filament out of the design.

If you read their ToC, that entails giving them rights to basically do whatever they want with your creations, including redistributing them without your permission. They also force you to tacitly declare that your models are released under Creative Commons. No thanks.

Plus, various people with pants on their head around the world get really cagey about balisong knives for some reason. Like they think they're super dangerous sentient objects capable of acting on their own above and beyond other types of folding knife. I'd rather not have anyone on there shrieking "think of the children!" at me because I designed a silly knife.

[–] [email protected] 4 points 11 months ago

Dig your style man. This is bitchin' ;)

[–] [email protected] 3 points 11 months ago (1 children)

Very cool! Though also seems like it might cause 3d printers to be more heavily regulated in some places. People can be irrationally afraid of things like this.

[–] [email protected] 5 points 11 months ago

More so than the 3D printing firearm enthusiasts?
