Design Concept: The Aracari – A "Smallest Big Knife" built for the Maker

#1

Post by Pengubandit »

Hi everyone,

I’ve been a long-time reader here and very long Spydie fan, admiring the way this community dissects steels, geometry, ergonomics etc. I’ve always been more of a reader than a poster, but I’ve spent the last few years modifying and building knives to learn, and fit my specific needs, and I feel like finally have something I feel is worth sharing with the group.

:bug-red-white

I have a lot of neat knives and each of them has their own charm but I often found myself wanting something from 2 or more different knives at the same time. That's when i began making and modifying them to fit my purposes.

I wanted to design the knife I couldn't find on the market—one that packed a full-sized sheepsfoot blade into a sub-compact carry footprint without sacrificing ergonomics.

I started with a bunch of sketches and 3d prints to get a feel for what I really wanted. I've had this design for a few months now and and petty happy with it.

The Aracari is what I call the 'Smallest Big Knife.' I named it after the small Toucan because of its compact size and the blade shape which looks kind of like the bird. While this specific design is entirely my own, it shares the same 'core' and pivot structure as the Spyderco Amalgam and borrows many ideas and design cues from many of my favorite knives.

There's too much to post on a single message but here's an overview of the general specs of this knife.

- Choked up grip is standard. I moved the choil as close to the pivot as possible and made a huge finger guard. This way I can grip as close to the edge as I can with my pm2 and para 3. I know it can be controversial but I personally love the Sydrrco choil.
- A 3.5" cutting edge in a 4.565" closed frame (8.030" OAL). I wanted as much usable blade for the size. 3.3oz (94g)
​- 0.100" Full Flat Grind in CPM MagnaCut. I aimed for 0.015" to 0.020" BTE for a slicy but tough cutting edge. Sharpened at 17.5 dps. Very slicey but sturdy
- All​ T8 Hardware for simple, one-tool maintenance.
​- The butter-knife spine: A smooth, polished, convexed spine with no jimping and a central divet. It acts as a comfortable extension of the index finger for a "pointer" grip and allows the spine to be used as a butterknife. Great for spreading jam and Nutella and is shaped so I lick the blade clean without poking or cutting my tongue.
​-Self-Supporting Tripod: When opened and placed blade-down on a flat surface, the tail of the handle and choil suspend the cutting edge up off the surface. This let's me safely put down the knife and pick it up to use it again safely.
​- Spyderco deep-carry wire clip for a lightweight, discreet carry that doesn't chew up pockets.

There's tons more considerations that I didn't mention but I'm around and happy to answer any questions.

Here's some mediocre images of the current version. I'll take some nicer ones later and some closer up details


I also only made it for a standard compression lock clip in this version, I've left enough space to eventually make it button actuated like the smock or sage 6.

So glad to finally be participating

Really love the edge to handle ratio. Handle looks comfortable too

Here's a few more pictures of the knife in hand.

I've been hesitant to clean it up and make it completely finished because I’ve always come back to it for changes after a few days but so far ive been satisfied with it in daily use.

One thing I've struggled with is finding a place to put a lanyard hole. It used to have a slightly more prominent back where I was able to leave a small hole right next to the lower screw (similar to how the Para3 LW does it now) but I wasnt happy with it because it compromised with the extended grip where the butt of the knife would be pressed into the palm. Trimming off that portion made it more comfortable and since I rarely use a lanyard I kept it off.

I'd still like to add a lanyard hole for those who like it so I'm thinking about something like a blind barrel with a cross hole similar to Chris Reeve knives or what the Paysan did to provide a more hidden lanyard hole.

Really, really well-thought-out. I would buy one. Very glad to hear you intend a button for the comp lock, as that would eliminate the only possible hot spot in your otherwise smooth handle. Awesome work!

Thanks, I have plans to build a button version of it but it'll have to be a left handed version for now since it would take too long/a lot of effort to remake the whole thing with lefty parts so it can have the button on the correct side (for me)

I did try a CME button for a bit but the cutout for it is too small to make that comfortable ans it kept falling off.

I just got some S90V steel so I'll try to make the next one out of that. I've never worked with it before but it did wear out my bandsaw balde pretty quickly as I was trying to cut a blank. I can definitely see where the extra cost is coming from on s90v blades, not just the steel but all the tools used to work on it get worn out so fast.

Looks like an incredibly useful tool; not flashy but practical (I hope that comes off as a compliment). Well done.

I still don't know what a maker is but the knife is definitely cool.

Say what you will, the Bugout is a very practical knife for most people. Knocking it out of the water is hard.
I'm happiest with Micarta and Tool Steel.

Top four in rotation: K390 + GCM PM2, ZCarta Shaman, Crucarta PM2, K390 + GCM Straight Spine Stretch.

Haha true, felt a little weird about the wording on that.
What is a maker?
Someone who makes?
A very philosophical question...

I consider myself some kind of maker, whatever that may be, and this was built as specifically as can be for me.

Really nice, thanks for sharing!

- Among other things the a bit more robust and "low" tip is something I personally really appreciate.

- And I get that right: You could add a button to the lock despite there is no cutout/choil in the blade but a relatively to the handle long cutting edge? That'd be great!

- Could you post a comparison pic, especially concerning the actual length of the grip area, with some popular Spyderco model?
Top three going by pocket-time (update October 25):
- EDC: Endela SE (K390). Endela SE (VG10), Manix 2 LW (REX45)
- Mountains/outdoors: Pac.Salt 2 SE (LC200N), Salt 2 SE (LC200N), Pac.Salt 1 SE (H1)

Yeah, I wanted something a little more blunt tipped than the Kapara and Drunken but with similar shape and size.

The button would fit just fine because of how high the grind is relative to the recaso/finger guard. They're sort of merged here similar to the Sheepsfoot Carribean. You can see in the closeup that nothing moves in front of the compression lock arm so it would be really easy to bolt on a stud and a matching cutout on the clip side of the handle. Thats actually next on my to do list (though it'll be a lefty version since the button is on the back side.) I might enjoy that though but I'm not sure until I try it. Kind of like a button CME upgrade.

Here's a few pics of other knives for comparison. My DLC coated Titanium Maxamet Para3 generally sees the most use, the rest I cycle through a bit more randomly.

Don't mind the rough finish, it's been through a lot of tweaking and tuning.

Same knives but closed. The only ones smaller when closed are the Para3 and Native 5 and not by a lot.

Next to some favorites. Extremely similar cutting edge to Drunken and Kapara but slightly tilted to give negative rake at the base, neutral at the mid-belly region and positive around the tip area (kind of like a recurve without making it harder to sharpen). It should allow for really good rope cutting without serrations. I'm not a huge fan of them though they have their place for sure.

The clearance exists because there's a huge non-choil

Love the overall idea and lines. I would personally make the finger guard smaller but I understand the reasoning behind it, it's purely subjective to me

Love that! :smiling-heart-eyes

Particularly the Excellent handle/edge ratio.

The only thing I’d possibly change would be to get rid of the raised area on the handle to make it a completely neutral grip.

Looks pretty good. I can't help thinking it's what you'd get if the Kapara and Amalgam had a baby.

Love it, it is like a more polyvalent Amalgam. The tip being lower is one of my favorite to do and to own.
I'm with ya on blade to handle ratio, that's pretty neat ! It's a particular exercice to be able to fit as much edge as possible while keeping everything function-driven as much as possible.

I'm having some limitations on my linerlocks, I've reached the best Edge to Handle ratio I can for now, but using a compression lock seems to free up some space behind the heel and on the kick.... A really well thought out design man, and congrats on bringing it to life :open-grin

Honest feedback, it sort of just looks like “one more knife” to me.

But I’m curious about how you prototyped this. Did you fabricate this from scratch? Or is this pieced together from another knife or two?

On the lanyard thing, the Spyderco lanyard obsession needs to stop 😂. Don’t add a flaw to a good design just so someone can run a lanyard thru it.

That's it! I was thinking Kapara when I first saw it, but it wasn't just that. It was more and different. I think describing the handle as Amalgam-like really rounds out describing the knife (at least in terms of existing Spyderco models).

Looks like just a modded Amalgam. He said it "shares the same core" and I can even see the faint filled in screw holes above the pivot from where the Amalgam had them.
