History, mentionings from the forums etc.

  • In this post on the Spyderco.com forum, from 19 February 2023, Sal Glesser shares some information on the design history of the Webfoot Sharpener and the 308F Golden Stone:

I invented the Triangle Sharpmaker in 1978. I invented the Golden Stone/Webfoot (Duckfoot) at the same time. The technology wasn't there to make the design so it sat for many years. We made the "Pro-File" stones as a fill while technology was growing. Patented the Golden Stone concept some 20 odd years later.

When we were finally able to make the concept in a real product, it was the Duckfoot. We built a steel embryo and plated diamonds on to the Embryo. When the technology was there to make the Golden Stone, we made it. While it is quite expensive to make, it is a very unique concept. Then we added the Webfoot to compliment the fine grit stone, and we used CBN instead of diamonds. We finally made a fixture to hold both pieces at 30 degrees inclusive (15 per side).

Now, 45 years later, we are finally able to bring the concept to a production piece available to you. Persistence is King.[1]

308 CBN Webfoot Sharpener

The Webfoot is a uniquely different approach to sharpening that can be used anywhere, set up in seconds, and doesn’t require oil, water, electricity, or any complicated clamps or fixtures. It is made of a single piece of carbon steel and coated in Cubic Boron Nitride (CBN)—a state-of-the-art superabrasive that is second in hardness only to diamond. Resting the wide end of the Webfoot on a flat surface and rocking it from side to side aligns its outer edges at the perfect 40-degree included angle for utility knife edges. Simply keep the plane of your blade vertical and draw it from heel to tip. The included ABS plastic base reduces that angle to 30 degrees for keener edges and thinner, high-performance knives. Laid on its side, it offers the perfect 12.5-degree angle for sharpening scissors and shears. With over 15 square inches of abrasive-coated surfaces of varying shapes and angles, the Webfoot can be used to quickly and easily sharpen a wide variety of edged and pointed tools, including those with serrated edges. It comes complete with detailed instructions and a high-quality suede pouch that also serves as a handy non-slip work surface.

The Webfoot is sold separately or as a kit with the Golden Stone™ fine ceramic sharpener.[2]
