Hey guys, was sitting around thinking about how much I love the idea of carrying extra gear on my knife sheath but how much I hated my current options. I like the idea of a hard case, something that could be easily attached, and something that wasn't an altoids tin. Also the idea of something that could be made waterproof seemed pretty nice too. Problem is, there isn't anything like that on the market that will fit the BK2 sheath without a bunch of overhang or being really big and sticking out real far.

So, I got to thinking how nice it would be if there were a way to make something that would fit it perfectly, shaped the same, be low profile but still allow a decent bit of storage. And having access to a semi-decent 3D modeling program and a rather slow workday, I came up with this. Mind you I haven't drawn up the lid yet, mostly because I haven't figured out how I would like it to attach.

Here is the pic.

Now right now this is just an idea, and the measurements are really roughly guessed, but I think it would work out fairly well, still allow the usage of the strap holes, and would only need 4 chicago screws to attach it to the front of the sheath. So far it is 20mm thick, which is just a hair bigger than 3/4", and the lid would add a little more, but I think it would add quite a bit more space than an altoids tin.

All that being said, and everyone understanding that this is just an idea, what do you think? Please be gentle.

Looks like a good case if you can figure out some way to keep the lid on where you can still get it off without having to take the 4 screws out.

The 4 screws would be to attach the bottom of the case to the sheath, not to attach the lid to the case. For that I am thinking strap with velcro or something.
 
Is the container something you would get into frequently, or just back up emergency stuff? I'd base my lid somewhat on that.
It could be held on with a hinge, like a tuperware lid, snaps, ranger bands, thumb screws, big flathead screws (tighten with a coil etc.), or many other ways.
Could you do it like a calculator lid? The lid could slide up from the bottom, and follow the grooves up the sides, and have a tab on the top to "click" in place.
Did you want it to be waterproof or sealed?
 
Definitely waterproof. I am thinking that if I made a lid that had a cutout that fit into the main compartment, by like say a couple of millimeters, then plasti-coted it, that would make it waterproof enough. Then, say from the sides a nylon strap with some simple velcro on it to secure it in place. Maybe some nubs to fit down in the screw holes where the screws would go for the chicago screws to attach it to the sheath.
 
I'll take 2 please.

Oh, wait, 3D rendering.....

Ok, then, when can you get 2 of these made? I'm thinking I'd like to have them by the end of next week, so, if its gonna be later than that, you'll have to kick me a bulk buyers deal.

Naw seriously, it looks good and I like the concept. While you are at it, come up with backing platform tha will fit the BK2 and BK10, I have a feeling we'll be needing those soon, as well.

Thanks, nice work by the way.

Nice job, Derek. I currently use an Otterbox 1000 for backup, but you're right, it does take up a fair amount of real estate on the sheath...although not bad. Holds a bit more gear than an Altoids tin, and is totally waterproof.

That said, I like the idea of an integral kit on the sheath, and your design is spot on! Get it, buddy!
 
I really like the idea! I think that a hinged lid that closes on an o ring would be great because if the lid wasn't secured to the box I know I would lose it one way or another...
 
I am not sure about an o-ring. One would be kinda hard to get that would fit that weird of a shape, and it might come out. Maybe a bead of silicone or something might work?

As far as a hinge, I am not sure that I could or would do that. Plastic hinge is bad news in my opinion, yet another thing that can fail, whereas a plain lid that is shaped to kinda sit in it a bit is pretty simple, and less likely to fail when you need it. I am leaning pretty heavily towards the nylon strap with velcro or snaps at this point, simply because it is pretty easy to get ahold of or manufacture.

Also I am trying to keep the total amount of material down, cause if I get the design good and tight I am actually going to get one made and right now the price for this bottom alone is $48-ish. If I get one I can probably cast more for less, but the first one is going to cost a bit. (Funny how jewelry and prop-making knowledge might prove useful for outdoor stuff.)
 
never thought of that . it would be hard to get a 0 ring to fit . unless maybe you got one verry large and cut it but then as you said 1 more thing to fail huh. this might be a genuine head scratcher lol
 
ohh i just looked at the drawings again . how bout a thin rubber gasket around the edge with a good lid fastening system .
 
Okay, few tweaks, and an idea for the lid. I like the idea of a small gasket, that would work well I think. To secure, wrap two pieces of 1" nylon webbing around, and where the ends would meet on top have either snaps or velcro or some quick release clips.

So, straps you would use for sheath on your leg would go on like normal. Then, on top of that, small straps for the box and lid. Then bolt on box using four chicago screws in the four holes. This will hold on the straps used to hold down the lid, and when you undo them to remove the lid, would still keep them in place to wrap over top of the lid when back in place. If using quick release buckle thingy the notches in the top could be left out completely.

For the inside of the lid I could make a recessed area to glue in a match striker (or double sided tape, whatev) or leave as is so a piece of sandpaper could be glued on for field sharpening.

I like that, a good gasket on a good solid lid and a couple of compression straps would be a great idea for securing I think.
 
Very interesting idea indeed. I have all kinds of doo dads taped to my sheaths. I make sure that every hard use FB that I take outdoors has a basic fire starting kit taped to it. This looks much nicer.
 
neat. how much to CNC? :) cast magnesium maybe? mmm.

though, as well, you might consider making your box ALSO be the sheath too. saves on assembly, etc mmm.

oh, include a method for attaching a hex wrench of the right size in there?

Good call, I could also use a 3/8" firesteel loop, it would save space of having to put it in the box.

I like it.

You guys already saw my method for attaching a hex wrench. Go to Lowes ya bums!

Seriously, you two want one of my allen wrench holders? Email me your info.

For a firesteel I really think that a kydex loop would be a better option. If I do it with this, it will have to be way bigger than a kydex one and still will probably not be as strong. (The material I will get this made from isn't the most resilient in the world for small applications. A box should be okay for the prototype, but for a firesteel loop, it would be a poor choice for materials.)

I would be having the first one made by these guys here: Shapeways

I have ordered tons of stuff through them and always been very satisfied with the results. Of course nothing this large or utilitarian. From what I am looking at on the rough draft price is at around $95-ish for the bottom and lid. Others could probably be made for less if I were to cast others myself. Just not sure what kind of material I can cast in that would work well for this kind of application. Will check next week when my casting guy gets back in town.
