"Nacre" Lift-tip Oyster Knife by Fourth Cliff Tool Co.

$5,533

The Nacre is an artful and elegantly designed lift-tip oyster knife by Fourth Cliff Tool Co. Oysters are a healthy and fun food to serve at parties, however the art and skill of opening oysters carries a certain mystique, and many people would prefer to leave the shucking to the professional. With proper instruction, a lift-tip designed knife can empower any home chef to shuck oysters with ease.

 The Nacre (see figure 02) is just this, and its sculptural form creates a conversation piece, as well as a beautiful treasure to display. For the aspiring chef in your life, this oyster knife would make a wonderful gift. This knife has been designed to balance functional and aesthetic values. Our goal is to develop products with a high residual value, taking everyday tools and transforming them into collectibles, soulful objects that will last a lifetime, to be passed down to next generations. By pledging, not only will you be supporting this product, you will be helping us to jump start Fourth Cliff Tool Co. and our whole line of seafood preparation tools.

Most oyster knife blades are made from commercial grade stainless steel. Construction of the handles can range from wooden handles riveted to a full blade (tang), or they can have polypropylene handles around the tang. 

"Our innovation is simply taking a multiple part assembly and integrating the design into one part."

Distinguishing characteristics: Our product is an investment casting in 440c (high carbon) stainless steel, heat treated and oil quenched, with a beautiful satin finish.

This 440c stainless steel is used to make tools such as chisels and surgical equipment for its corrosion resistance, and its durability. It contains increased carbon for maximum hardness, and chromium is increased for corrosion resistance. The blade has been heat treated with an oil quench process to increase its hardness. This corrosion resistant steel lends itself well for liberating the oyster from its shell in its briny environment.  The Nacre knife is offered in a satin finish.   

The Product name: Nacre (/ˈneɪkər/ nay-kər also /ˈnækrə/ nak-rə),[1] also known as mother of pearl, is an organic-inorganic composite material produced by some molluscs as an inner shell layer; it is also what makes up the outer coating of pearls. It is strong, resilient, and iridescent. Citation: Nacre. (2015, May 22). In Wikipedia, The Free Encyclopedia.

The Story of Fourth Cliff Tools:

In 1985 Jamie fell in love with the oyster while living and working in Baltimore, Maryland. The Cross Street Market, a historic marketplace built in the 19th century in Federal Hill, was a gathering place for doctors, lawyers, fishermen, masons, artists and architects. Shopping for fresh produce and fish, as they made their way down the two block long city market, all would then join together at the raw bar at the far end for oysters and beers. In the early 80’s, Dori spent a winter living in the Florida Keys, shucking oysters in a grass shack. Subsequent restaurant jobs were easily landed at various restaurants in her home state of Rhode Island. While earning her Master’s Degree in Education, she worked as a professional shucker, refining the art and skill of both preparing and eating oysters.

In the winter of 1988, Jamie moved to Providence, Rhode Island. Always on the lookout for an oyster experience, he met a shucker (Dori) serving oysters with the same love of life and seafood. They have been life partners ever since, sharing their love of the oyster with the people around them. After long careers in education and product design, the Fourth Cliff Tool company was formed in January of 2015, with the vision of creating artfully designed seafood preparation tools, which are intended to last a lifetime.

"We formed the Fourth Cliff Tool Company in January 01, 2015 providing artfully designed seafood preparation tools"

Fourth Cliff Tool Company’s first product “Nacre” has gone through concept development, design development for functional and aesthetic evaluation, through an iterative process of 3d modeling CAID computer aided industrial design and numerous ABS 3d printed parts (see Figure 05) .

 We have had a prototype 3d printed in stainless steel through a printing process called "direct metal laser sintering" (DMLS) which prints parts in metal ( see figure 06).

 We have developed our tooling and have in hand our first run polished prototypes investment cast in 440c stainless steel and polished to a # 6 satin finish. see figure 07

Fourth Cliff Tool Company’s additional products are in concept design development and will also be offered shortly. We are focusing on the launch our first product the "Nacre", and will develop the other products after we have our sales established. 

Our tooling has been completed and finished prototypes approved. The funding raised on Kickstarter will be used for manufacturing, finishing and packaging of the first production run of the Nacre.

Risks and challenges

This is our first Kickstarter campaign after years of design and manufacturing experience, and we are very confident in our ability to deliver the "Nacre" Lift-tip Oyster Knife by Fourth Cliff Tools in a timely manner. If the Nacre Lift-tip Oyster Knife is successfully funded, we will need to make sure everything goes according to plan in order to meet the promised deadline. We have manufacturing, operations, and logistics set up and ready to go. Our tooling has been completed and finished prototypes approved. The funding raised on Kickstarter will be used for manufacturing, finishing and packaging of the first production run of the Nacre. We have a manufacturing and finishing commitment in place. Although we do not see any direct risks and challenges, there are always indirect or unseen tasks that may present during the process of production. We hope to run everything as streamlined as possible and also ahead of schedule to make this a great experience for our backers.
