Knife maker sharpens production: Design & Engineering

Mention the name Connor Toor to most knife aficionados and you’ll receive a knowing nod. That’s because the founder and CEO of Toor Knives Inc. has developed a product line of which any entrepreneur would be envious, and he did so in less than a decade. Add to that, in 2018 the U.S. Marine Corps sent the rifle squad leader to Afghanistan for a year-long deployment just as his fledgling business was beginning to take off.

Once he was back home in El Cajon, California, Toor picked up where he had left off — developing and manufacturing a leading line of tactical, sportsman and every-carry knives that Toor estimates has a 1.5% to 2% global market share of fixed-blade knives.

“It was probably back in 2013 or so that I built a forge in my backyard and started tinkering around making fireplace hooks and random cool stuff, so I decided to try my hand at knife making,” Toor said. “I watched some YouTube videos, made a few trips to Home Depot for some mild steel and got pounding. I scrapped a lot of metal along the way, but it finally started coming together.”Toor admits that he knew little about manufacturing when he first fired up his forge.He’s since attended the machine technology course at San Diego City College, where he learned how to write G code and what machine to use for which process, adding to his bachelor’s degree in accounting and business management from California State University San Marcos.Toor initially only made knives for friends. But those friends told their friends, and it wasn’t long before Toor began posting photos on the craft marketplace Etsy. He built a website, started earning a little money and, over the next year or two, realized he might be on to something much more than a hobby.”So, I moved out of the backyard and into a U-Haul storage unit,” Toor said. “I had two 110-volt outlets and was chronically short on power, swapping out the drill press for the grinder, the grinder for the bandsaw, and so on. But it worked. I was making knives.”He decided to take his venture more seriously. He brought in a friend and traded the storage unit for “some real commercial space,” Toor said. “We knew then that we’d have to develop a formal manufacturing process and figure out how to make these things at a larger scale.”

Part of that process involved machine tool and equipment purchases, which included grinders. Toor noted that his company started with belt grinders that had surface grinding attachments and were manually fed. To overcome issues with accuracy, Toor Knives outsourced grinding, with blades being ground on double-disc, Blanchard and large feed surface grinders.

When the time was right to bring grinding back in-house in 2019, Toor said he purchased a used SGS-1640AHD automatic feed surface grinder built by Tustin, California-based Kent Industrial USA Inc., which the company uses to make the blade blanks flat after heat treatment. The hardened steel workpieces have a hardness of about 60 HRC.

After becoming familiar with the Kent USA brand, Toor Knives purchased a new Kent SGS-2040AHD automatic feed surface grinder in early 2023. “We knew the controls, so we just stuck with it,” he explained.
