The Slice 10597 Auto-Retractable Seam Ripper is ideal for industries where fixed blades are prohibited, or for anyone looking to find a safer alternative to a manual seam ripper. Even as retractable seam rippers are available on the market, Slice introduces the first version with advanced ceramic blades. And because the blades are Slice safety ceramics, they feature our finger-friendly cutting edge. Slice seam ripper handles have a long, thin profile and are made of durable glass-filled nylon. They are compatible with both the rounded-tip and pointed-tip seam ripper blades.
From the Manufacturer
Why Ceramic Blades? Hardness & Sharpness.
On the Mohs hardness scale, Metal blades are rated 5.5 vs. Ceramic blades at 8.2, second only to diamonds. Harder edges maintain sharpness longer, cut better, and require replacement far less ceaselessly. If truth be told, depending on use, you’ll be able to go weeks or months without having to replace a single ceramic blade. They also last up to 10x longer!
Saving Money Just Makes Sense.
A single Slice ceramic blade is equivalent up to 10 high-end double-sided metal blades or up to 20 high-end single sided metal blades. With regards to safety, less blade changes also mean less risk of injury.
10536 Round Blade
The 10536 blade, in addition to its safer cutting edge, has a rounded tip to guard against accidental punctures. It glides smoothly between stitches and cuts without tugging at the surrounding fabric.
Ergonomic and Compatible Handles
Slice 10536 and 10537 blades were designed for the 10596 (manual retraction) and 10597 (automatic retraction) seam ripper models, but they also fit in several craft handles, allowing you to select the best combination for your needs. Our seam ripper blades are compatible with both our craft knife models (10548 and 10589), our replaceable-blade scalpel (10568), and the shorter Precision Knife, with its unique handle (10580).
10537 Pointed Tip Blade
The 10537 blade has a pointed tip to slip into very small stitches.It glides smoothly between stitches and cuts without tugging at the surrounding fabric.
Our safety is in the blade
When industrial safety managers first encounter our products, they try to compare them with existing safety knives, but Slice tools are in a class of their own. Even as other manufacturers redesigned their knife handles for safety, we’re the only company that redesigned the blade itself.
About the Startup
Describe your product in 3 words.
Safe. Elegant. Innovative.
How did you get a hold of the idea for this product?
Slice has a commitment to donate 1% of all sales to fund Autism research, primarily through our main benefactor, Lucile Packard Children’s Hospital Stanford University.
What makes your product special?
Our proprietary blade manufacturing process combines a unique sharpening angle and thicker ceramic material, resulting in a very unique patented blade that’s safer to the touch vs. metal, and requires pressure to initiate the cut — via our handles. Hence, general blade handling and blade-replacement with Slice ceramic blades is infinitely safer vs. those same activities with traditional metal blades, yet still allows for a wide range of cutting applications.
What has been the best part of your startup experience?
You can’t simply duplicate a metal blade in ceramic material and achieve what we have created with our current products. There’s a tremendous amount of engineering required on not only the blades and handles individually, but there’s also an improbable amount of engineering required on the combination of the handles and the blades working together in order to produce the desired balance of safer-usage and cutting capability. Even today, for our next generation of products that are currently under development, we spend the majority of our time finding the right balance between handle and blade through trial and error and what seems like endless prototypes. The best part definitely has to be seeing peoples first-time reactions when cutting cardboard with Slice and they realize how awesome the Slice ceramic blade is.
