Happy with this invention!

My husband has recently asked me to start buying small jars of peanut butter. One of the reasons is that he can not get all the gooey goodness off the walls of the big jars. Being the penny pincher that I am, I kind of wanted to resist because the big jars last so much longer (less trips to the store because he eats PB like candy) and are a better deal cost wise. However,I complied to his request....Until I spotted the PB-JIFE! I showed him the picture of it on The Grommet. He seemed intrigued, so I bought it. He is happy with his new kitchen tool. I think my penny pinching self might just get to buy the big jars of PB again, thanks to the Grommet. Love your website!!More > < Less

I got this as a gift for my husband. He uses it every day for his P B J sandwich prep. A family favorite tool.

Every Last Bite

Fed up with sticky knuckles and wasted food, Maker Landon Christensen created this peanut butter knife to help solve a common kitchen problem: getting every last bit of deliciousness out of peanut butter jars. Yes, even the big ones.

Landon pulled from his art background along with his PB&J-making prowess as a dad to create the PB-JIFE. The long, stainless steel blade has a curved tip specially designed to reach into all the contours of a jar and scrape the bottom, sides, and rim. But PB-JIFE is not just for when the jar is almost done. The strong, extra-broad blade is sturdy enough to stir peanut butter, natural nut butters, jams, thick oils, and other spreads, too. And it can deliver an ample portion to an eagerly awaiting sandwich with just one swipe. It’s one of the most helpful knives around—jar none.
