Sharks are said to be natural fighters, but the "shark tank" on Sunday caused the sharks to leave the tank to chase after two entrepreneurs.

Marc Lickfett and Mikael Soderlindh are the creators of Knife Aid, a knife sharpening service for postal services. Drop your blunt blades on the posts and in less than a week, and for $ 10 per knife, the company makes them sharp enough to cut through a pineapple or a rope (as the sharks Kevin O'Leary and Rohan Oza demonstrated ).

Soderlindh has experience building successful global brands, including the Swedish clothing brand Happy Socks. But due to a failure in the past, the two came on the show and sought the help of a shark who understands the US market better.

"We had a different brand in the American market without American people being involved in the business," said Soderlindh. "I will not make that mistake again."

Shark Lori Greiner liked her concept: "You're fresh, you're unique, you're different, you've already removed the packaging, it's really pretty good, I think you're smart at knowing what that is Market here. "She offered them $ 200,000 and an additional $ 200,000 in credit for a 20 percent interest.

The two entrepreneurs did not respond to the offer and discussed their plans to promote their retail store service Angry Greiner picked up her cell phone and flipped through her contact list: "Listen, folks, I could say, 'Pick a contact, any contact.' All I've offered you is what you ask.

But O & # 39; Leary wanted to have her on Team Chef Wonderful. He offered them $ 400,000 for 20% of their company. "I have all the same contacts, but I have something she does not have. I'm a chef, wonderful." Chef Wonderful is huge in cakes, chocolates and meat. "Google him, he's fantastic."

Fits to O ' Leary's offer sweetened Greiner's deal through a partnership with Oza. Soderlindh and Lickfett would receive twice as many sharks at the same price. Oza said, "If you buy the Queen of Retail along with the King of Branding, that's for you."

But Greiner was not the only one who could partner. O'Leary teamed up with his shark colleague Barbara Corcoran. They offered $ 500,000 for 20%.

But the creators of Knife Aid were reluctant to accept both offers. Greiner noticed that they kept looking at Mark Cuban, who was particularly quiet: "Are you waiting for Mark to make you an offer?"

Cubans believed he could strengthen Knife Aid's brand awareness, but he would wait What they have decided with the offered deals.

Before Soderlindh stepped into the hall to discuss business with Lickfett, he asked the sharks how passionate they were about his business and how much time they would invest. O'Leary and Greiner insisted on being the best shark for this job.

Cuban shook his head over his Mithaie: "Damn, are you grovel enough? I do not beg or rant. I am an (expletive) shark. "

" I'm not overtaxed to do anything that is necessary, "Greiner replied, and to prove her point, she decided she had waited long enough and left the tank to find Soderlindh and Lickfett. "You want to know something about passion, I'm not sitting and waiting, I want this deal."

O'Leary was right behind her, followed by Oza and Corcoran. Soderlindh was interested in making a deal with Greiner and Oza, but wanted them to bring the $ 500,000 together. The two sharks agreed quickly and concluded the deal.

"It's something I would never have dreamed of when four sharks got in the way behind us," said Soderlindh.

Back in the tank, Cubans agreed, "It's a new shark breed that's bustling." [19659028] Autoplay
