Hanan & Sliver Compression Lock Flippers

[RamZar]

The Spyderco Hanan & Sliver Compression Lock Flippers are two exciting upcoming folders from Taichung.

Anyone have specs on these specially blade length?

So I did a screenshot comparison.

- In an image editor, I layered the three images to line up the Spyderco logo on the mat to ensure equal size. Fortunately the camera angle was consistent even if the framing was different per shot.
- Lined them up and counted pixels: Overall, Handle. Used math for the blade length.
- Compared the numbers to Chaparral's mm measurements on the website and averaged them for a pixel-to-mm mulitplier



So take these with a grain of salt as they're just dirty approximations.

Sliver (This one is curved)
OAL: 8.07" (205 mm)
Handle: 4.73" (120 mm)
Blade: 3.34" (85 mm) -- probably more like 3.5" blade

Hanan (I might not have angled this one 100%)
OAL: 6.80" (173 mm)
Handle: 3.85" (98 mm)
Blade: 2.95" (75 mm)

I'm guessing the Hanan will have similar specs to the Positron and the Sliver is along the lines of the Caly3.5 in size.

Wow. Now that's dedication. Much respect.

[SF Native]

Yup. Thanks for the size comparison.
That Hanan looks way cool.

My pleasure. These two are of interest to me, so I was going to do it eventually anyway.

I've been waiting for the mini-Hanan since late-2015 when Brad posted something conspicuously like a comp lock flipper for a SpyderCollab. Did not expect it this fast.

Here's the custom:

And here is what I believe was the original prototype submitted:

Are these S30V also?

[RamZar]

Thank you Holmin for the blade length estimates.

[RamZar]

Both are S30V.

[Bodog]

Sigh. Would've preferred just about anything else. The hanan is still tempting. Wish they'd have used 204P.

my question: teflon washers in the sliver? we'll see if they learned from the ouroboros.

OAL: 8.07" (205 mm)
Handle: 4.73" (120 mm)
Blade: 3.34" (85 mm) -- probably more like 3.5" blade

Just curious, on the blade length are you going by the beginning of the edge at the tang or from the further point outward of the handle? Looks like this one could technically have more cutting edge than blade length depending on how it's measured.

Honestly, I did not measure the blade because it is so confusing how I'm supposed to do it.

So I did the Blade = OAL - Handle, which lines up with furthest point of the handle to tip.
What I probably did not account for properly was the angle of the blades relative to the handles, hence my followup estimates being around 3.5" and 3" respectively.

The Sliver has my attention. Pretty interesting design. Ergos look good and I like how pointy the blade shape is.

It's a Taichung model, unlike the Ouro or Junior, and my impression is that Teflon is a Japanese G10 or Italian phenomenon. Also, to the best of my knowledge, Spyderco has never dropped a Teflon flipper. Heck, I think Hinderer's the only maker to try that. So, cautiously optimistic.

that's encouraging! it was your sacrificial lamb experience of the ouroboros that changed my mind on purchasing the knife -- looking forward to more news on this one.

Howdy everyone, and thanks for the portion of compression-lock flipper love that's been directed at the Sliver. I wish I could share more details and thoughts on the design, but want to wait till I have some time with a production sample. (I wouldn't want to be giving out any details that aren't consistent with what will be available for purchase.)

But, I will say this, hoimin's dimensional estimates are pretty spot on for the Sliver, I was working towards a 3 1/3" blade length.

Thanks again for the enthusiasm for the Sliver, and I'll be back with more info when I can,

Come on Paul. Throw us a bone. It looks great. Was this an evolution of the ouroboros?
Did the design start just after? Was it by request or a crazy idea after a beer or three?

Paul I'm extremely impressed and I haven't even held one yet. You and I must have very similar taste in knives.

It isn't often that a folder is as beautiful closed as it is open. I love the tear drop shape it has when closed. Do you have pics of a custom that you based this off of or is it just based on a rendering/idea?

I wish I had the skill/equipment/time to crank out a few customs, but I prototype all my submissions to Spyderco as best as I'm able. Everything gets fully 3D modeled in a CAD package. I do a lot of design refinement virtually, iterating and branching variants off the base concept. After letting things breathe for a bit, I pick my favorite version and finalize it. The physical prototypes end up consisting of real knife hardware bought from online knifemaking supply shops with the blade, handles, liners, etc. 3D printed out of plastic by a rapid prototyping service. Then I assemble and finish everything. I'm getting pretty good at it, though; one of the last flipper submissions I made had real bearings and actually flipped smoothly and locked up solidly. Maybe I can dig up pics of the old Sliver prototype I sent to Spyderco for the later design discussion thread I'll start.

And I'm an avid reader of and listener to these forums... so don't be surprised if some of what's discussed here trickles into my designs.

Thanks to everyone for the enthusiasm,
