Mail in knife sharpening shark tank

You're referring to the popular TV show Shark Tank!

The company you're thinking of is likely "Sharpal", a mail-in knife sharpening service that appeared on Season 7 of Shark Tank in 2015.

Here's a brief summary of their pitch:

Sharpal's founders, David and Lisa, introduced their company as a convenient and affordable way to sharpen knives at home. They claimed that their system, which uses a proprietary sharpening stone and a simple, easy-to-use device, could sharpen knives in just a few minutes.

The Sharks were impressed with the product's ease of use and the potential market size, but they were also concerned about the competition from established knife sharpening services and the high cost of shipping and handling.

In the end, Sharpal secured a deal with Shark Lori Greiner, who invested $200,000 in exchange for 20% equity. The company has since continued to grow and expand its product line, offering a range of sharpening solutions for various types of knives and tools.
