Welcome to the STRATO-biner project page.

STRATO, deriving from Stratum meaning "One of several parallel horizontal layers of material arranged one on top of another."  A suitable name for the layered style of design featured by STRATO. 

Strato is an EDC carabiner designed with customizable twist.

As an avid knife collector and knife maker, I've always enjoyed the flexibility liner lock knives offer with respect to the scale material.  We decided that was a feature we wanted to include in our next project.  In doing so, we can offer various materials that best suit taste, mood and budget without compromising strength and utility.   For this project we are offering 6 reward tiers.  

Please review the various finishes and materials and check out the pledge options outlined at the bottom of the page.

Construction

Each STRATO is composed of a main body "core", and 2 exterior "scales".

STRATO -- Cores

We're excited to offer 2 core variants for the STRATO project.  The titanium core will offer a lightweight and sleek design and in contrast, the the tool steel cores will offer greater strength, wear resistance and utility.

Titanium Core

Titanium Core -- We've selected Grade 5 Alloy (6Al4V) for the titanium versions because of its incredible strength characteristics. 

Tool Steel Core

Tool Steel Core -- We've selected tool steel alloy 17-4 heat treated to H900 for its Hardness and incredible wear resistance.  The Tool Steel STRATO core also offers extra jimping and a pry bar for more utility and function.


STRATO -- Scales

Titanium STRATO scales (Tumbled)

As with the STRATO core we're offering scales made of grade 5 Alloy (6Al4V) and with a tumbled finish.


Titanium STRATO scales (Fallout anodized)

Same as above, with a semi matte twice anodized blue-bronze.  A favorite colorway with all of the Ti2 Design products we offer.  Also known as "denim anodizing".


Brass STRATO scales

For this project we've selected brass alloy 260 also known as "cartridge brass".   All of the great brass hues, with much better strength and wear resistance in comparison to common brass alloy 360.  These are acid washed and tumbled giving them a textured patina look.


Copper STRATO scales

We've selected copper alloy 110 for fans of copper and red hues.   Copper 110 has good wear resistance and durability.  These are acid washed and tumbled giving them a textured patina feel.


Zirconium STRATO scales

Zirconium -- Coolest Metal Ever? Its rare and expensive and not for everyone, but the finish is unlike any other metal. When heat treated, a dark grey / black oxide layer forms at the surface that is very hard. These offer excellent wear resistance and a sleek dark look. 

All new gate design for STRATO!

All new design, all new feel.  

Specific to this project, we've designed an integrated, asymmetrical gate that offers great torsional rigidity for a lifetime of use.

As with all of the carabiners made by Ti2 Design, the gate is made from grade 5 Alloy (6Al4V) and features an ambidextrous design allowing positive action right or left handed.  


Strategic Jimping

The design is a result of a multitude of ergonomic tweaks. Jimping is strategically placed for the various utilities within the design.

 The STRATO's stylish shape coupled with a "milled" sculpted pry bar offers excellent strength for chiseling, prying and scraping.

The large key ring hole allows key rings to slide out of the way while used in different configurations and accommodates split rings, para-cord and lanyards.

Custom Hardware

PLEASE NOTE - The prototypes pictured on this project page are assembled with prototype hardware.  For all of the rewards shipped we will be assembling finished products with titanium hardware and look of the hardware may differ slightly.

Risks and challenges

I have a background in design, machining and experience managing production jobs. I know the kinds of problems that arise in the shop and how to deal with them quickly and efficiently.
If this project funds and in order to fulfill we will need to:
1. Source Material -- Multiple vendors and quotes are lined up.
2. Machine the parts -- Lowest risk of the process, our machines are optimized for parts like this insuring quick production and high quality parts.
3. Finishing -- We have multiple finishing tumblers that can accommodate the tumbling needs.
4. Fulfillment -- We do our fulfillment in house to offer direct communication with our backers. Our experience on our last projects have helped us develop accurate fulfillment protocol.
The success of this project depends heavily on getting the word out. Every blog or social networking post counts, so please share. Thanks for your support.
